Front

What is the process called when water, wind, ice, or gravity loosens and carries away fragments of rock?

Back

Erosion

Front

What is the first process that must happen to any rock during the formation of sedimentary rock?

Back

Existing rock is weathered into sediment and eroded away.

Front

Define the term 'weathering' in the context of rock formation.

Back

Weathering is the process of breaking down rocks into smaller pieces through physical or chemical means.

Front

What are the two main types of weathering?

Back

Physical weathering and chemical weathering.

Front

Explain the difference between erosion and weathering.

Back

Weathering is the breakdown of rocks, while erosion is the movement of those broken pieces away from their original location.

Front

What role does gravity play in the process of erosion?

Back

Gravity helps to pull materials downhill, contributing to the movement of sediments.

Front

What is sedimentary rock primarily composed of?

Back

Sedimentary rock is primarily composed of particles of minerals and organic materials that have been compacted and cemented together.
