Processes of Weathering and Erosion

Front

What is weathering?

Back

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

Front

What is erosion?

Back

Erosion is the process that moves pieces of rock by wind, water, and ice.

Front

What are the three types of rocks?

Back

The three types of rocks are igneous, metamorphic, and sedimentary.

Front

What is an igneous rock?

Back

Igneous rock is formed from the solidification of molten material.

Front

What is a metamorphic rock?

Back

Metamorphic rock is formed from existing rocks that undergo heat and pressure.

Front

What is a sedimentary rock?

Back

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

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks, while erosion moves the broken pieces.

Front

What is deposition?

Back

Deposition is the process where sediments are laid down in new locations.

Front

How does water contribute to weathering?

Back

Water can cause physical weathering through freeze-thaw cycles and chemical weathering by dissolving minerals.

Front

What role does wind play in erosion?

Back

Wind can carry small particles of sand and dust, eroding surfaces over time.
