| How does a sedimentary rocks come from? | form at or near the surface |
| Properties of Rocks | always solid, formed by 1 or more minerals, classified by how they form |
| Define clastic sedimentary rock | made of fragments of rock cemented together |
| Where does the rock cycle begin and end? | it has NO beginning or end |
| What is the process when one rock changes into another type? | the rock cycle |
| Lava | molten rock that has reached the Earth's surface |
| Magma | molten rock beneath the Earth's surface |
| Define extrusive igneous rock | have small or no crystals because lava cools quickly on the Earth's surface |
| Define intrusive igneous rock | have large crystals because magma cools slowly beneath the Earth's surface |
| Define chemical sedimentary rock | minerals in water crystalize to become rock |
| example of clastic sedimentary rock | Breccia |
| example of chemical sedimentary rock | limestone |
| example intrusive igneous rock | granite & gabbro |
| example of extrusive igneous rock | rhyolite and basalt |
| how do intrusive igneous rocks form? | slowly inside or beneath the earth's surface |
| how do metamorphic rocks form? | changes with heat and pressure but remains solid |
| what are the steps in creating a sedimentary rock? | formed by weathering, moved by wind and water, deposited in layer - older on bottom, layers become pressed |
| how are rocks and minerals different | rocks made up of minerals and do not have crystal structures; minerals have definite composition and a crystal structure |
| How do sedimentary rocks form? | near Earth's surface; no heat involved, cementation causes parallel bands form under pressure |
| How do extrusive rocks form? | quickly on the earth's surface |
| How does sedimentary rock form into a metamorphic rock? | rock must undergo changes through increased heat and pressure |
| How does a metamorphic rock form into a igneous rock? | rock must be exposed to heat, change to molten rock, cool and crystalize either inside or outside |
| How do you know if a rock is intrusive igneous rock | small or no crystals |
| How do you know if a rock is extrusive igneous rock? | has large crystals |
