Quick Answer: What Is Another Name For Physical Weathering?

What is the most powerful agent of weathering?

waterWeathering and erosion, along with the gravity-driven effect called mass wasting, are the fundamental processes by which rock is broken down and removed, collectively called denudation.

The most important agent in both weathering and erosion is water, in both its liquid and solid states..

What are 4 types of physical weathering?

Physical WeatheringFrost wedging. Frost wedging happens when water filling a crack freezes and expands (as it freezes, water expands 8 to 11% in volume over liquid water). … Heat/Cold Cycles. … Unloading.

What are the 6 types of physical weathering?

There are six types of physical weathering:Exfoliation: also called unloading; the outer layers of rock break away from the rest of the rock due to heat expansion.Abrasion: moving material causes rock to break into smaller rock.Thermal expansion: outside layers of rock become hot, expand, and crack.More items…•

What is another name for physical?

Some common synonyms of physical are corporeal, material, objective, phenomenal, and sensible.

What are 5 types of weathering?

These are freeze-thaw, onion skin (exfoliation), chemical and biological weathering. Most rocks are very hard.

What are the main agents of physical weathering?

Wind, Water, Gravity There are three agents of physical weathering that can cause abrasion: moving water. wind. gravity.

Which of the following is the best example of physical weathering?

An example of physical weathering is the process where rocks become cracked as a result of freezing and thawing of water.

What are the 3 agents of weathering?

Agents responsible for weathering include ice, salts, water, wind and plants and animals. Road salt and acids represent a form of chemical weathering, as these substances contribute to the wearing away of rocks and minerals as well.

What are the 5 agents of physical 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 are 3 examples of physical weathering?

These examples illustrate physical weathering:Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. … Ice wedging. Ice wedging causes many rocks to break. … Plant roots. Plant roots can grow in cracks.

What are the two types of physical weathering?

There are two main types of physical weathering:Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.

Which is an example of physical weathering?

Physical Weather Examples Physical weathering occurs when rock is broken down through mechanical processes such as wind, water, gravity, freeze-thaw cycles, or the growth of roots into rock.
