Weathering Processes - Part 3 - Quiz

Which of the following is NOT an agent of physical weathering?

• Wind

• Water

• Temperature changes

• Rust

What causes chemical weathering?

• Temperature changes

• Pressure changes

• Chemical reactions

• Animal burrowing

What is oxidation?

• The process of rocks being broken by wind

• The reaction of oxygen with minerals in rocks

• The breakdown of rocks due to pressure

• The melting of rocks

What is an example of oxidation?

• Ice wedging

• Formation of rust on iron-rich rocks

• The breaking of rocks by tree roots

• Rocks falling in a landslide

What causes acid precipitation?

• Burning fossil fuels

• Earthquakes

• Melting glaciers

• Plant roots

If a scientist found an iron-rich rock with a reddish-orange coating, what process likely caused this change?

• Ice wedging

• Exfoliation

• Oxidation

• Abrasion

Farmers notice that their limestone fences are wearing away faster than their granite fences. What is the best explanation?

• Limestone undergoes more physical weathering than granite.

• Limestone is more affected by chemical weathering, such as acid rain.

• Granite is exposed to stronger wind and water erosion.

• Granite reacts with oxygen faster than limestone.

A student places two identical rocks outside—one in a dry, shaded area and one in an area exposed to acid rain. What would likely happen?

• The rock in the shaded area will weather faster.

• The rock exposed to acid rain will show more chemical weathering.

• Both rocks will weather at the same rate.

• Neither rock will experience any weathering.

Why do buildings and statues made of marble wear down faster in cities than in rural areas?

• Cities have higher temperatures that cause expansion and contraction.

• Cities have more acid rain from pollution, which reacts with the marble.

• Wind and water erosion are stronger in cities.

• Cities have more burrowing animals that break apart marble.
