Weathering Quiz

What is physical weathering?

• The process of breaking down rocks and minerals into smaller pieces without changing their composition.

• The process of rocks and minerals being formed into larger pieces due to pressure.

• The process of rocks and minerals turning into liquid form due to high temperature.

• The process of rocks and minerals changing their composition without breaking down into smaller pieces.

Give an example of physical weathering.

• Volcanic eruption

• Plant roots breaking rocks

• Freeze-thaw cycles

• Chemical reaction

How does temperature contribute to physical weathering?

• Leads to the formation of new minerals in rocks

• Causes rocks to become more compact

• Causes rocks to expand and contract

• Has no impact on physical weathering

Explain the process of frost wedging also called freeze/ thaw

• Frost wedging or freeze/thaw is the process of water seeping into cracks in rocks, freezing, and expanding, causing the rock to break apart.

• Frost wedging or freeze/ thaw is the process of rocks being eroded by wind and rain.

• Frost wedging or freeze/thaw is the process of rocks being compressed by the weight of snow.

• Frost wedging or freeze/thaw is the process of rocks melting due to high temperatures.

What are the different types of weathering processes?

• Hot and cold weathering

• Sunny and rainy weathering

• Mechanical and chemical weathering

• Day and night weathering

How is chemical weathering different from physical weathering?

• Chemical weathering is caused by extreme heat, while physical weathering is caused by water erosion.

• Chemical weathering only affects soft rocks, while physical weathering affects hard rocks.

• Chemical weathering involves the breaking of rocks due to physical force.

• Chemical weathering breaks down of rocks changing minerals into new minerals

What are the effects of weathering on rocks?

• Rocks can break down into smaller pieces

• Rocks become more colorful and vibrant

• Rocks become softer

• Rocks become stronger

How does weathering contribute to soil formation?

• Weathering creates new rocks from scratch, which then form soil

• Weathering has no impact on soil formation

• Soil is formed by the accumulation of dust and debris, not from weathering

• Weathering breaks down rocks into smaller particles, which then mix with organic matter to form soil.
