Three Types of Rock Processes

How are sedimentary rocks formed?

• Sediments

• When magma or lava cools

• With heat and pressure

• When sediments are pushed together in layers

How are metamorphic rocks formed?

• When a rock changes from heat and pressure

• When a rock becomes magma

• When sediments are pushed together in layers

• By wind

How are igneous rocks formed?

• Lava

• When sediments are pushed together in layers

• When magma and lava cools and hardens

• Through heat and pressure

What is the rock cycle?

• A type of music

• When one type of rock is changed into a different type of rock

• When rocks melt

• A life cycle

What is weathering?

• The breaking down of rocks by water, wind, ice, roots, etc.

• The weather

• Rain, wind, ice

• The temperature outside

What is erosion

• A barrier to prevent a landslide

• The movement of broken rock to a new place

• The breaking down of rock

• The inside of your ear

NGSS.MS-ESS2-4

A rock formed from material that is deposited by water, wind, or glaciers. It is formed from this material when it is squeezed or cemented together when water moves through the rock and soil. It could have fossils.

• igneous

• metamorphic

• sedimentary

• deposition

NGSS.MS-ESS2-4

Rocks that are formed from cooled magma that are often very hard or full of small holes (porous). They have minerals in the form of crystals.

• igneous

• metamorphic

• sedimentary

• deposition

A rock that has gone through a transformation by heat, pressure, or other processes. It is then a new type of rock that usually has bands and swirls in it.

• igneous

• metamorphic

• sedimentary

• deposition

Earth’s recycling process where igneous, sedimentary, and metamorphic rocks change into and form one another.

• weathering

• erosion and transport

• burial and compaction

• the rock cycle
