EARTH DIMENSIONS The Earth’s Dimension The Shape of the Earth The general shape of the earth is like a sphere. However, that sphere is not perfect. The diameter of the earth at the equator is 12,757 kilometers. The diameter taken at the poles is 12,714 kilometers. The difference indicates that the earth has a bulge of about 43 kilometers at the equator. The Hydrosphere The hydrosphere is the layer of water that covers approximately 70.8% of the surface of the earth. The layer is relatively thin. In scale, it is like the skin on an apple. The hydrosphere includes all the oceans, but technically it encompasses all water surfaces in the world, the inland seas, lakes, rivers, and underground waters. The average depth of the oceans is 4 kilometers (2 miles), more than five times the average height of the continents. The mass of all the world's oceans is approximately 1,350,000,000,000,000,000 (1.35 x 1018) metric tons, or about 1/4400 of the total mass of the earth. The mantle and core are the heavy interior of the earth, making up most of the earth's mass. The Lithosphere The lithosphere comprises two shells, the crust, and ridged mantle and is about 80 kilometers (52 miles) thick. It accounts for the land surface and under ocean features of the earth including mountains, valleys, and the ocean floor. The lithosphere is divided into many rigid tectonic plates. The mantle extends from the base of the crust to a depth of about 2900 km (about 1800 mi). Except for the asthenosphere, the mantle is believed to be solid, and its density increases with depth. Shearing of the plastic, partially molten rocks of the plastic mantle, the asthenosphere, 100 km (60 mi) thick, enables the continents to drift across the Earth's surface and oceans to open and close. The dense interior of the earth below the asthenosphere is divided into the stiffer mantle, surrounding an outer core and inner core. It is believed that the outer core is composed of iron and the inner core of iron and nickel.

The Atmosphere Atmosphere is the thin envelope of solids, liquids and gases surrounding the earth. It is held to the earth by the force of gravity. It consists of four distinct layers, whose boundaries are not precise. They are:

1) The troposphere extending from sea level to about 8-16 kilometers (5-10 miles) above the earth

2) The stratosphere up to about 48 kilometers (30 miles) 3) The mesosphere up to about 96 kilometers (60 miles) 4) The thermosphere up to about 500 kilometers (300 miles) or more

23

Activity Sheet for Learning Experience #10 page 2

NOTE: The upper region of the troposphere is often regarded as a separate region, the exosphere

Water on Earth Just how much water is there on (and in) the Earth? Here are some numbers you can think about: The total volume of the earth is about 1,083,230,000,000 cubic kilometers (a cubic kilometer is a cube measuring one kilometer on each side). The total water supply of the earth is about 1,358,880,000 cubic kilometers. Total freshwater on Earth is about 37,600,000 cubic kilometers or less than 3% of all the Earth’s water. Of the fresh water, less than 1% is available for humans. According to the following charts, only about 8,500,000 cubic kilometers of water is fresh water and available to humans. For comparison, a cubic kilometer of water contains a trillion liters or 1,000,000,000,000 liters. This is enough water for about 140 liters for every person on Earth. Most of the fresh water on Earth is stored in the 29,000,000 cubic kilometers of water found in glaciers and icecaps, mainly in the polar regions and in Greenland. About 12,900 cubic kilometers of water, mostly in the form of water vapor, is in the atmosphere at any one time. If it all fell as precipitation at once, the Earth would be covered with an additional 2.5 cm of water. The United States receives a total volume of about 17 cubic kilometers of precipitation each day. Of the freshwater on Earth, much more is stored in the ground than is available in lakes and rivers. More than 8,200,000 cubic kilometers of fresh water is stored as ground water. Most of that water is less than a kilometer below of the surface. There are about 240,000 cubic kilometers of water stored as fresh water in lakes, inland seas, and rivers. Distribution of Water on the Earth

26

Activity Sheet for Learning Experience #10 page 5 You will be making a model to represent the earth’s volume and the volume of the earth’s water resources. Follow the following directions carefully. Seven cardboard pieces from cereal boxes are required. Each piece should measure about 13 x 13 cm. The finished panel for the model will measure 12 x 12 cm when cut. The folded panel will measure 10 x 10 cm when finished. The one cardboard piece will be used to make a template that will be traced to make the six panels for use in the model. Patterns: Patterns are the full scale drawings provided to make your own templates. Templates: Cardboard templates are made from paper patterns. One effective way to attach the paper pattern to card template is by using rubber cream adhesive or white glue. In general, the dimensions of the pattern and template are the same. Panels: Panels are the result of tracing the templates on another cardboard surface and marking the locations of the connecting/scoring/folding lines and the locations for hole punching. The panels are the cut from the card. Additional cuts are made to enable the rubber band to serve as a connector. These cuts are made perpendicular to the nearest outer edge through the center of the punched hole. The panels are completed by scoring the connecting/folding lines. The scoring may be done with a shape instrument or by marking hard with a pencil or ballpoint pen. Making the Template Paper patterns have been provided to aid in the construction of a template. The template will be traced later on to the panels that will be used to construct model. The template requires that you obtain a paper pattern and apply that pattern to the one surface of a 13 x 13 cm cardboard piece. Glue carefully to provide the smoothest surface possible. Allow the glue to dry completely. After the glue has dried, cut carefully on the line provided that will cause the panel to measure 12 x 12 cm. Each hole should be centered over the circle near each corner. Carefully punch the four holes in the locations shown by the pattern.

27

Activity Sheet for Learning Experience #10 page 6 The corners of the pattern/cardboard piece must be cut to provide the completed template for tracing of the panels for the model. Each cut should be perpendicular to its nearest outside edge. Each cut should follow the line that would intersect with the center of the each punched hole. Making the Panels Place the template from the previous example on the remaining 13 x 13 cm cardboard pieces. Carefully trace the outside of the template on the plane side of the cardboard with a pencil. Remove the template. Punch the corner holes in the panel. Cut the corners in the same manner that the template was cut previously. The panel should be the exact same shape as the template. Place a straight edge or ruler on the plane side of the cardboard panel and draw lines parallel to the outside edge of the panel. The four lines must be drawn 1cm from the edge. Press hard with the pencil or ballpoint pen. You will be folding on these lines later. Pressing hard will indent the surface and make the fold more uniform. Repeat the procedure until six panels have been prepared. Making the Model Fold the panels on the indented lines that are 1 cm from the outside edge. Fold the panels so that the fold forms a 90° degree angle with the plane side of the panel. Each model is constructed by placing rubber bands over the portion of the punched holes that are remaining. Connect two panels together. Connect the third panel to form the corner of the three dimensional box. Continue to add panels until a closed cube is formed. The cube may be permanently connected together with white glue. Ask your teacher if they want the cube glued at this time.

Activity Sheet for Learning Experience #10 page 7 Adding the Grids Each model will require 6 10 x 10 cm grids be added to its surfaces. Sheets of centimeter gird squares are attached to this learning experience. Cut the sheets into individual squares and glue to the outside surfaces of the cardboard panels. The model you have created represents all the total volume of the earth. It is an approximate model. Your model has a total volume of 10 cm x 10 cm x 10cm which equals 1000 cubic centimeters. If we let one cubic centimeter equal 1,000,000,000 cubic kilometers (1 billion cubic kilometers), the total 1000 x 1,000, 000,000 equals 1,000,000,000,000 cubic kilometers (1 trillion cubic kilometers). At the beginning of this learning experience, it was stated that the total volume of the earth is about 1,083,230,000,000 or nearly the same amount. Therefore, your model may be said to be an approximation of the volume of the earth. On your model, what would represent the volume of all the earth’s water?______________. Remember, the total model you have constructed represents 1 trillion cubic kilometers. The volume of water you are trying to represent is 1 billion cubic kilometers. On your model, what would represent the volume of all the earth’s fresh water?____________ Fresh water is only 3% of the total amount of all the earth’s water.

29

Activity Sheet for Learning Experience #10 page 8 Your model has a side that measures 10 centimeters. Each side therefore is 100 millimeters long. If you let the 100 millimeters represent the average diameter of the earth (12,736 kilometers), how many kilometers does one millimeter represent?_____________

The average depth of water in the ocean is about 4 kilometers. Based on the previous example above, what part of a millimeter would represent the average depth of water in the ocean?______________

The troposphere extends to about 16 kilometers above the surface of the earth. What part of a millimeter would represent the troposphere on your model?______________

The stratosphere extends to about 48 kilometers above the surface of the earth. What part of a millimeter would represent the stratosphere on your model?______________

The mesosphere extends to about 96 kilometers above the surface of the earth. What part of a millimeter would represent the mesosphere on your model?______________

The International Space Station (ISS) orbits at about 376 kilometers above the earth. How many millimeters represent the level of the orbit of the ISS?________________

The lithosphere is extends to about 80 kilometers below the surface of the earth. What part of a millimeter would represent the lithosphere on your model?______________

GLOSSARY

Abrasion Resistance: The ability of a material to withstand wear from its surface

Abrasive: Any hard material used in the wearing, grinding or

rubbing away by friction such as sandpaper, emery, garnet or the like.

Atmosphere: The envelope of gases surrounding the earth and held to it

by friction. It has four layers: • troposphere – from sea level to 8-16 kilometers (5- 10 mi) above the earth • stratosphere - up to 48 kilometers (30 miles) • mesosphere – up to 96 kilometers (60 miles) • thermosphere – up to 500 kilometers (300 miles) or more

Calcium Carbonate: One of the most abundant inorganic (nonliving) substances in nature. The white powder or colorless crystals are the major part of sedimentary rock, particularly in marble, limestone and chalk, as well as in animal shell and bones. They are used in antacids, tooth powders, white paints, cement and lime as well as other important chemical uses.

Cementation: The process where sediments are joined together into

hard, compact rock. Common sedimentary cements are iron, silica and lime.

Chalk: A limestone or soft form of calcium carbonate made of

marine shells. It is white or light colored, fine-grained, easily broken up and liquids easily go through it.

Cleavage: The splitting of a rock or mineral. Splitting in one place

is one-way cleavage, two places, two-way cleavage and three places three-way cleavage. Some rocks do not split cleanly but break into pieces with uneven surfaces.

Compaction: The process of pressing sediment together because of

an increase in weight from deposits on top or by pressure from the Earth’s movements.

Compression: The changing of the Earth’s crust through folding and

faulting by pressure from sediments above or by contraction (squeezing) stress.

36

Conglomerate: Sedimentary rock made up of pieces of rock or minerals in sand, silt or cementing material.

Crystallization: A metamorphic process where crystal mineral grains

are made in rocks. Deposition: The process where rock sediments, particles and other

materials are laid down naturally in beds, veins or deposits.

Erosion: The loosening and wearing away of the Earth’s surface. Extrusive: Any igneous material that has been ejected or poured

out onto the Earth’s surface. Glacial Till: Mixed material deposited by glacier ice and made up of

clay, silt, sand, gravel and boulders. Glacier: A large mass of land ice by the compacting (squeezing

together) of snow. It flows slowly down slope under its own weight.

Grain Size: The size or range of sizes of grain particles or mineral

grains in a sediment or rock. Hardness: Minerals are rated 1-10 according to hardness on the

Mohs’ Scale of hardness. 1 is very soft (talc) and 10 is very hard (diamond). Your fingernail is about 2.

Hydrochloric Acid: An acid with a strong odor that is highly corrosive

(wears away), toxic and irritating. Hydrosphere: The part of the Earth that is water, including liquid

water, ice and water vapor on the surface, underground or in the atmosphere.

Igneous Rock: Rocks formed when hot magma in the Earth cools

rapidly and becomes a solid. Magma forced out of the Earth’s surface makes extrusive igneous rocks (obsidian and pumice) while magma that fills in between layers of rocks and cools slowly is called intrusive igneous rocks (granite).

Intrusive: Molten, hot liquid material, forced into older rocks or

between rock layers, which hardens before it reaches Earth’s surface.

37

Lower Mantle: The part of the Earth’s mantle 1,000 kilometers below the surface.

Lithosphere: The solid or land part of the Earth made up of the crust

and upper mantle. Magma: Liquid, hot rock (molten) material made inside the

Earth’s surface which make up igneous rocks. Mantle: The inside part of the Earth below the crust and above

the core. It goes down to a depth of 3480 kilometers below the surface.

Mortar: A strong, bowl like vessel used to crush a substance

into powder using a pestle. Metamorphic Rock: Sedimentary or Igneous rocks that have been changed

by heat, pressure or chemical action. Minerals: Naturally occurring nonliving (inorganic) substances

with a definite chemical makeup, crystal forms, and chemical and physical properties.

Plane: A flat or level surface. Plutonic Rock: Medium to course grained intrusive igneous rock made

by the hardening of magma. Property: A quality that describes something or how something

works. Resistance: This works against (opposes) something like the flow of

current. Rock Cycle: The different stages Earth’s materials may go through

when they go from one kind of a rock to another. Rocks: Hard, solid parts of the Earth’s crust. Most are made

up of a combination of minerals. Sedimentary Rock: Rocks made up of parts of older rocks, which have

been broken up and carried away, then deposited gradually, usually in layers.

38

Sediment: Pieces of rock or mineral that are carried by wind, water or ice, which end up in layers on the surface of the Earth.

Streak: The color of the powder making up rocks that we get by

rubbing the rock or mineral across a piece of unglazed tile.

Texture: The way a rock looks or the way a rock or mineral is

made up, such as the grain size or shape. Tectonic Plate: One of several large, movable blocks of a continent or

ocean crust that move as one piece. Weathering: The natural breakdown of rocks and minerals by the air

and other things like wind, rain and temperature changes.
