Rocks, Minerals, Erosion, and Weathering

What is the process by which rocks and soil are moved from one place to another?

• Condensation

• Erosion

• Weathering

• Deposition

What type of weathering occurs when water gets into the cracks of rocks and freezes, causing the rock to break apart?

• Water erosion

• Ice melting

• Rock splitting

• Frost wedging

How does chemical weathering change the composition of rocks?

• Chemical weathering changes the composition of rocks by creating new minerals.

• Chemical weathering changes the composition of rocks by increasing the size of minerals.

• Chemical weathering changes the composition of rocks by reducing the weight of minerals.

• Chemical weathering changes the composition of rocks by dissolving or transforming minerals into new substances.

What effect does weathering have on the shape of mountains over time?

• Weathering has no impact on mountain shape.

• Weathering causes erosion and shapes mountains over time.

• Weathering causes mountains to shrink.

• Weathering causes mountains to grow taller.

Name one example of a mechanical weathering process.

• Volcanic eruption

• Frost wedging

• Wind erosion

• Chemical weathering

How does erosion contribute to the formation of valleys?

• Erosion creates mountains instead of valleys.

• Erosion has no impact on the formation of valleys.

• Erosion wears away the land, creating channels that eventually form valleys.

• Erosion leads to the expansion of valleys.

What role does vegetation play in preventing erosion?

• Vegetation accelerates water runoff

• Vegetation attracts more water and increases erosion

• Vegetation stabilizes the soil with its roots, reduces the impact of rainfall, and slows down water runoff.

• Vegetation has no impact on soil stability

What are the consequences of weathering on man-made structures?

• Weathering can lead to erosion, corrosion, cracking, and weakening of man-made structures.

• Weathering can lead to strengthening of man-made structures.

• Weathering has no impact on man-made structures.

• Weathering can cause man-made structures to become more durable.

How does weathering impact the formation of caves?

• Weathering breaks down rocks, creating cracks that water seeps into, dissolving the rock and forming caves.

• Weathering causes caves to collapse rather than form.

• Weathering creates caves by solidifying rocks instead of dissolving them.

• Weathering has no impact on the formation of caves.

Explain how weathering and erosion are interconnected processes.

• Weathering breaks down rocks into smaller pieces, which are then transported by erosion.

• Weathering creates new rocks, while erosion breaks them down.

• Erosion causes rocks to grow, while weathering transports them.

• Weathering and erosion have no relationship.
