Processes and Principles of Erosion and Sedimentation

Types of Erosion Erosion is a natural process by which soil and rock material is loosened and removed. Erosion by the action of water, wind, and ice has produced some of the most spectacular landscapes we know. Natural erosion occurs primarily on a geologic time scale, but when man's activities alter the landscape, the erosion process can be ...

12.3: The Sediment Cycle

In a sense, the sediment cycle is simpler than the water cycle, because after sediment is formed it inevitably moves downhill toward places of rest. From the perspective of the Earth's surface, sedimentary processes are basically a matter of source, transport, and sink. (Scientists like to use the term sink for a kind of place to which matter ...

Frost wedging, oxidation, hydrolysis. River erosion, wind erosion, glacial movement. Both processes are vital in shaping the Earth's topography and play a crucial role in soil formation and the ...

Sedimentation and Erosion

Weathering breaks down earth materials from large sizes to small particles, and happens in place. ... Agents of erosion— wind, water, ice, and waves—move weathered materials from one place to another. When erosion takes place, sedimentation—the deposition of material—also eventually occurs. Through time, sediments are buried by more ...

Weathering

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. 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. No rock on Earth is hard …
