What forms igneous rocks when it cools?

• sediment

• magma

• lava

• deposited materials

What grain size is created when magma cools slowly?

• large

Rocks can change through many different processes in the rock cycle. Which one below does NOT occur on Earth's surface?

• melting

• deposition

• weathering

• cooling

Why are grain sizes different between intrusive and extrusive rocks?

• rocks cool quickly with extrusive rocks causing large crystals.

• rock cools slowly with intrusive rocks causing large crystals

• rock cools slowly with intrusive rocks causing medium sized crystals

• rock cools quickly with extrusive rocks causing medium sized crystals

How are rocks and minerals different (choose 2)

• rocks are naturally occuring solid mixtures

• They are the same but have different components

• They are the same but different sizes

• Minerals are a naturally occurring inorganic solid with a definite chemical structure

How are sedimentary rocks formed?

• from magma

• formed because of changes in temperature and pressure

• formed when loose materials become pressed or cemented together.

• formed when lava cools on Earth's surface

Deposition, sediment, erosion and weathering all work together to create igneous rocks.

• true

• false

Pressure and heat change igneous and sedimentary rocks into metamorphic rocks.

• true

• false

How does magma deep within Earth become sedimentary rock?

• Magma cools on the surface, is weathered, eroded, and deposited.

• Magma cannot become sedimentary rock.

• The rock has to be weathered first.

• Igneous rock is broken by tectonic plates before being deposited in sediment
