Rock Cycle Flashcard

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical, chemical, or biological means.

Front

What type of rock is limestone?

Back

Limestone is an example of sedimentary rock.

Front

What is erosion?

Back

Erosion is the process by which rock, sand, and soil are broken down and carried away by natural forces such as water, wind, or ice.

Front

What are sedimentary rocks formed from?

Back

Sedimentary rocks are formed from sediments, which are small particles of rock, minerals, and organic material.

Front

Which process takes the longest time to complete: movement of small pieces of rock by flowing water, rivers rising due to storms and floods, weathering of a rock to form small rocks and sand, or evaporation of water from the leaves of a plant?

Back

Movement of small pieces of rock by flowing water takes the longest time to complete.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various stages: igneous, sedimentary, and metamorphic.

Front

What is compaction in the context of sedimentary rocks?

Back

Compaction is the process where sediments are pressed together under pressure, leading to the formation of sedimentary rocks.

Front

What is cementation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together, forming sedimentary rock.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of magma or lava.

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed from existing rocks that are changed by heat, pressure, or chemically active fluids.
