Do Now: Rocks1. List the three main types of rocks AND how they form.

1. Igneous- forms from lava or magma (melted rock above or below surface)

2. Metamorphic- formed from heat and pressure (at times appears squished)

3. Sedimentary- formed from pieces of other rocks or minerals through chemical or physical changes

2. For each type of rock (I, M, S), list and DESCRIBE the subcategories for each AND provide an example from the power point for each.

A. Igneous

a. Intrusive- forms from magma INSIDE the earth

b. Extrusive-forms from lava on the exterior of the earth (volcanoes)

B. Metamorphic

a. Foliated- has crumpled lines or lanes

b. Non-foliated-no crumpled layers

C. Sedimentary

a. Clastic- made of pieces of sand and/or pebbles of pieces of rocks and minerals

b. Chemical – made from evaporation process or chemical changes of a mineral

c. Organic- made of up once living material (fossil fuel or has fossils in it)

Do Now: Types of CleavageDescribe and provide an example1. Cleavage in one direction:

1. Flakes, or thin sheets

2. Micas, Hornblende and Talc (small flakes)

2. Cleavage in two directions

1. At least two flat edges not always 90°

2. Feldspars

3. Cleavage in three directions at 90°

1. Cubic cleavage

2. Halite, Galena, Pyrite

4. Cleavage in three directions NOT 90°

1. Slanted corners

2. Calcite

5. Cleavage in four directions

1. Crystal – four to six sides

2. Quartz

6. Concoidial

1. Rounded sides

2. Sulfur

Do Now:1. What are the TWO types of Igneous Rocks? Describe and Provide

an example of each.

Extrusive- forms on the surface of the earth from lava or a volcano (Examples: Pumice and obsidian)

Intrusive- forms from magma under the earth’s surface (Examples: granite and basalt)

2. What are the TWO types of Metamorphic Rocks? Describe and Provide an example of each.

Foliated- layers (gneiss and schist)

Non-Foliated- no layers (Marble and Quartzite)

3. How do Igneous rocks form?

From the heating and cooling or lava and magma

4. How do Metamorphic rocks form?

From heat and pressure deep within the earth’s crust
