What is a common agent of weathering?
Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.
What is the main source of weathering?
Weathering causes the disintegration of rock near the surface of the earth. Plant and animal life, atmosphere and water are the major causes of weathering. Weathering breaks down and loosens the surface minerals of rock so they can be transported away by agents of erosion such as water, wind and ice.
Are glaciers an agent of weathering?
Glaciers are extremely effective weathering and erosional agents. A glacier is capable of carving deep valleys into bedrock as well as scraping all loose material (soil and weathered bedrock) off from a landscape.
What are the three types of weathering agents?
There are three types of weathering, physical, chemical and biological.
What are chemical weathering agents?
Chemical weathering changes the composition of a mineral to break it down. The agents of chemical weathering include water, carbon dioxide, and oxygen. Living organisms and humans can contribute to chemical weathering.
What are the four agents of physical weathering?
