Weathering and Erosion

Which of the following is an example of mechanical weathering?

• Acidic groundwater dissolving limestone

• frost wedging

• Paper being burned

The process that breaks down rocks and other materials on Earth's surface is called

• weathering

• erosion

• soil conservation

• decomposition

Which type of climate will have faster chemical weathering?

• Hot and Wet

• Cold and Dry

• Hot and Cold

• Cold and Wet

Carbon dioxide (CO2) combines with water as raindrops fall through the atmosphere. This makes a weak acid, called carbonic acid. Carbonic acid is a very common in nature, where it works to dissolve rock. Pollutants, such as sulfur and nitrogen from fossil fuel burning, create sulfuric and nitric acid. Sulfuric and nitric acids are the two main components of acid rain, which speeds up chemical weathering.
