What makes up organic sedimentary rock? 

Plant and animal remains

100
What is a reason that metamorphic rocks are found on earths surface if they are formed underground?

Erosion and tectonic plates shifting. 

100

What are the two main types of minerals found in igneous rock?

felsic and mafic. 

100

What are rocks made up of?

Minerals

100

If sediment is compacted and cemented, what type of rock will it form?

Sedimentary

200

How are sedimentary rocks formed?

When sediment is compacted and cemented together. 

200

Do metamorphic rocks form on the surface of earth or under the surface? 

Under the surface 

200

What are the two types of igneous rocks?

Intrusive and Extrusive. 

200

Does magma or lava cool faster? 

lava

200

If a rock undergoes high heat and high pressure, what type of rock will it turn into?

Metamorphic

300

What are the two groups that sedimentary rocks fall under?

Foliated and non-foliated. 

300

What are the two types of metamorphic rocks?

Foliated and non-foliated. 

300

Explain the difference between intrusive and extrusive rocks. 

Intrusive rocks are formed when lava cools on the earth surface. Extrusive rocks are form when magma cools under the earths surface. 

300

Explain the reason of why magma or lava cools faster. 

Lava is on the earths surface causing it to cool faster. Magma is underground where temperatures are still high. 

300

If magma cools off, what type of rock will be formed?

Igneous

400

What are the 3 types of sedimentary rocks?

Chemical, organic, clastic

400

How long does it take metamorphic rocks to form? 

Millions of years

400

How are igneous rocks formed?

When magma or lava cools off. 

400

What is sediment made up of?

Pieces of rock

400

What are the two processes in which sediment is formed?

Weathering and Erosion

500

What makes up clastic sedimentary rock?

Sediment. Rock pieces, soil, etc. 

500

How are metamorphic rocks formed? 

By undergoing high heat and pressure

500

What is the difference between magma and lava?

Magma under earths surface, lava is after a volcanic eruption. 

500
If I have four layers of sediment, which layer would be considered the oldest? 

The fourth(bottom layer)

500

If a metamorphic rock melts, what will be formed?

Magma
