Mr. Perez
Chapter 8 Section 3 Metamorphic rocks and rock cycle

2. Section 2 Vocabulary
Lava- molten rock material that exists at or above Earth’s surface
Igneous rock- rock formed when melted rock material from inside Earth cools
Extrusive- melted rock material cools on Earth’s surface
Intrusive- melted rock materials cools below Earth’s surface
Sedimentary rock- sediment collected in layers and compacted together

3. Igneous Rock Details Igneous Rocks Type Form from molten rock called
Have cooling rate that is
Have crystal size that is
Extrusive

5. Organize igneous rocks
Igneous Rocks can be
Light colored
High silica content
Have
Are called Granitic
Dark colored
Low silica content
Basaltic
Are called

7. Classify Sedimentary rocks
Detrital
Chemical
Organic
Form from
Made of grains of minerals or other rocks
Dissolved mineral in seawater, geysers, hot springs, or salty lakes
Living matter that has died
How form
Moved and been deposited in layers by water, ice, gravity or wind
Evaporation or other chemical processes
Piled up and compressed into rock
Where form
Land or water
Water
Land or ocean
Examples
Sandstone, Shale, Conglomerate, Siltstone
Halite
Chalk, coal, limestone

8. Section 3 Vocabulary Pressure- force applied over a given area
Metamorphic rock- new rocks that form when existing rocks are heated or squeezed by not melted
Foliated- rocks that have visible layers or elongated grains of mineral
Nonfoliated- rocks that do not have distinct layers or bands of minerals
Rock cycle- cycle that describes how different kinds of rock are related to one another and how rocks change from one type to another
