Rocks and the rock cycle

Front

What are the three main types of rocks?

Back

Igneous, Metamorphic, Sedimentary.

Front

How are metamorphic rocks formed?

Back

Metamorphic rocks are formed by heat and pressure.

Front

What process transforms pumice into sandstone?

Back

Weathering and erosion to sediment, then compaction.

Front

What is the process that leads to sedimentary rock formation?

Back

Weathering and erosion.

Front

Which of the following is NOT accurate: Metamorphic --> Heat and Pressure --> Sedimentary?

Back

This statement is NOT accurate.

Front

What is the process of melting and cooling in the rock cycle?

Back

It refers to the formation of igneous rocks.

Front

Define sedimentary rock.

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is the role of compaction in the rock cycle?

Back

Compaction helps to form sedimentary rocks by pressing sediments together.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from cooled magma or lava, while sedimentary rocks form from accumulated sediments.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process of rock formation and transformation.
