Directions: Read the passage.
Chemical Weathering is a process that breaks down rock through chemical changes. This type of weathering produces a rock that has a different make up from the original rock. The agents of chemical weathering are water, oxygen, carbon dioxide, living organisms, and acid rain.
Water weathers the rock by dissolving the rock. Oxygen causes red or brown rust to form on some rocks and makes the rock soft and crumbly. Carbon dioxide produces carbonic acids that easily weathers marble and limestone. Living organisms produce weak acids that dissolve rock around roots. Acid rain, formed by burning coal, oil, and gas, causes very rapid chemical weathering.
Mechanical and chemical weathering often work together to break down rock and other substances at Earth’s surface.
