Geology Part 2-Rocks and Minerals

Front

What are rocks made of?

Back

Rocks are composed of different kinds of minerals.

Front

What is a sedimentary rock?

Back

Sedimentary rocks form when layers of sand, silt, clay, and mud are compacted and cemented together.

Front

What type of rock forms from extreme heat and pressure?

Back

Metamorphic rock forms from extreme heat and pressure applied to existing rocks.

Front

How can igneous rock be transformed into metamorphic rock?

Back

Igneous rock can be transformed into metamorphic rock if it is heated and put under pressure for long periods of time.

Front

What is the main characteristic of metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that have been changed by heat, pressure, or chemical processes.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks form from cooled magma or lava, while sedimentary rocks form from the accumulation and compaction of sediments.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process of rock formation, breakdown, and reformation through various geological processes.

Front

What are minerals?

Back

Minerals are naturally occurring, inorganic solids with a definite chemical composition and crystalline structure.

Front

What is an example of an igneous rock?

Back

Granite is an example of an igneous rock.

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks into smaller pieces by natural forces such as wind, water, and temperature changes.
