Earth Science Weathering

It is the process of breakdown of rocks at the Earth’s surface, by the action of water, ice, acids, salts, plants, animals, gravity and changing temperatures.

• Erosion

• Weathering

• Mud Flow

• Debris Flow

It occurs when rocks surface is frequently exposed to water, wind and gravity.

• Freeze - thaw

• Exfoliation

• Abrasion

• Dissolution

Polluting gases, like sulfur dioxide and nitrogen oxide dissolve in rainwater to make stronger acids. When this rainwater falls, we get acid rain. This acid attacks many rock types, both by solution and hydrolysis, seriously damaging buildings and monuments. This type of chemical weathering is called ___________

• Hydrolysis

• Acidification

• Carbonation

• Hydration

This is the main and immediate effect of weathering.

• Erosion

• Sedimentation

• Deposition

• Dissolution

Base your answer to the following question on the graph above, which shows the average yearly precipitation and temperature have on the type of weathering that will occur in a particular region. The amount to chemical weathering will increase if

• air temperature decreases and precipitation decreases

• air temperature decreases and precipitation increases

• air temperature increases and precipitation decreases

• air temperature increases and precipitation increases
