"Rock Cycle"

Sponge:
1) What is the difference between the two types of igneous rocks?
2) What rock is created through heat and pressure?

- Review/complete crystal size investigation (p. 129)
- Complete "Igneous Rock Questions" (p. 131)
- Draw rock type chart on p. 132 with notes about each type of rock
a) Sedimentary rocks
Made from eroded sediments cemented into rock
Made in oceans, swamps, deserts - depends on the kind of sedimentary rock
b) Igneous Rocks
Made from cooled and hardened lava/magma
Intru...

"Rock Cycle: Crystal Size Investigation"

Sponge:
1) How do igneous rocks form?
2) How do metamorphic rocks form?

Review yesterday's observations
- Metamorphic rocks used to be other rocks
- Igneous rocks can be extrusive (form on Earth's surface) or instrusive (form inside the Earth)

Demonstrate how crystals form with salol: melt in hot water, form crystals in cold water
- Record observations in a chart on p. 128

Complete crystal size investigation (p. 129)
- Question: Why do some igneous rocks have la...

2) ______________ fossils help geologists determine how old a rock is.

Rock cycle notes (p. 124): in a t-chart
- Igneous Rocks:
Form when lava/magma cools and hardens
2 types: extrusive, intrusive
- Metamorphic Rocks:
Form from heat and pressure inside the Earth

Igneous Rock Observations (p. 125)
