Unit 5: The Rock Cycle

Front

What is sediment?

Back

Sediment is small pieces of rock, minerals, or organic material that have been broken down through weathering and erosion.

Front

What process breaks down rocks into smaller pieces?

Back

Weathering is the process that breaks down rocks into smaller pieces.

Front

What is erosion?

Back

Erosion is the process by which sediment and other materials are moved from one location to another, often by wind, water, or ice.

Front

What type of rock is formed from cooled magma or lava?

Back

Igneous rock is formed from cooled magma or lava.

Front

What are the two main types of igneous rock?

Back

The two main types of igneous rock are intrusive (formed inside the Earth) and extrusive (formed on the surface).

Front

What is metamorphic rock?

Back

Metamorphic rock is rock that has been changed from its original form due to heat, pressure, or chemically active fluids.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process by which rocks are formed, broken down, and reformed over time.

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process by which sediments are pressed together under pressure, reducing their volume.

Front

What is cementation?

Back

Cementation is the process by which dissolved minerals crystallize and glue particles of sediment together.

Front

What type of rock is formed from the accumulation of sediment?

Back

Sedimentary rock is formed from the accumulation and compaction of sediment.
