Chapter 5/6.9

• As glaciers started to retreat they melted and left behind a sea over Indiana. As that sea evaporated the particles from the living substances settled to the ground and reacted chemically to each other and the water to form chemical sedimentary rocks.

Chapter 7/8.3

• Differential Weathering: Rocks weather at different rates.

• Mass movement: downslope movement of earth materials due to gravity, can occur quickly or slowly.

• Abrasion: Is the grinding and wearing away of rock surfaces through the mechanical action of other rock or sand particles.

Chapter 7/8.3• Erosion: process in which the materials of

Earth’s surface are loosened, dissolved, or worn away and transported from one place to another by a natural agent, such as wind, water, ice, or gravity

• Mechanical weathering: produces smaller pieces

• Chemical Weathering: Chemical alteration of minerals, changes both the composition and physical appearance of the rock.

Chapter 9.1• Evapotranspiration: all water that is lost from

an area• Precipitation: water of any form that falls to

the earth• Evaporation: when liquid water changes to a

water vapor (gas)• Condensation: When water vapor turns to

liquid gas• Transpiration: plants and animals release

water vapor into the atmosphere

Chapter 10.1

• Groundwater: water beneath the ground.• Well: hole that is dug to below the level of the

water table and through which groundwater is brought to Earth’s surface.

• Spring: natural flow of groundwater to Earth’s surface in places where the ground surface dips below the water table.

Chapter 10.2

Chapter 10.4

• Seasons

Chapter 17.1

Chapter 17.2

• Convergent: 2 plates move towards each other

• Divergent: Away from each other• Transform: Slide past each other

Chapter 17.3

• Transform: earthquakes• Convergent: Volcanic island arc, trenches,

volcanoes, and mountains• Divergent: Sea floor spreading, mid ocean

ridges

Chapter 17.4

• Pacific Plate

Chapter 17.5

• Puzzle like fit• Animal fossils• Plant fossils• Climate clues• Rock formations

Chapter 17.6

• Hot material rises• Cool material sinks• This creates a circular motion

Chapter 17.8

• 1. continental crust• 2. lithosphere• 3. asthenosphere• 4. oceanic crust• 5. Mantle

Chapter 17.9

• The Atlantic Ocean is expanding because of the divergent plate boundaries which causes sea-floor spreading. The Pacific ocean is shrinking because it has convergent plate boundaries with subduction.

Chapter 18.1

• Supervolcano• Stratovolcano (composite)• Cinder Cone• Shield

Chapter 18.2

• Caldera: large crater, can form when the summit or side of a volcano collapses into the magma chamber during or after an eruption

• Pyroclastic Flow: swift-moving, potentially deadly clouds of gas, ash, and other volcanic material produced by a violent eruption.

Ch. 21.1

• Widespread• Distinct (recognizable)• Occur over a large area• Exist for a relatively short period of time

Chapter 21.2

• sedimentary

Chapter 21.3

• Law of Superposition says that the older layers of rock are on the bottom while the newer layers are at the top.

• Cross-cutting relationships says that the rock cutting through layers of rock must be younger than the layers it’s cutting across.

groundwater replace the original organic materials that were covered by layers of sediment with new materials.

Chapter 24.2

• Carbon Cycle: Carbon dioxide is absorbed when plants are undergoing photosynthesis, oxygen is released as a by product. Plants also form carbohydrates which is consumed by animals and is the basis for life. Other organisms release carbon dioxide into the atmosphere during respiration. The cycle starts all over again.

Chapter 24.2

• Nitrogen Cycle: Nitrogen is an element used by organisms to produce proteins. Nitrogen fixing bacteria have to convert nitrogen from the atmosphere to be used by organisms to produce proteins. This cycle continues as animals eat one another and as waste is excreted by animals.
