What are the 7 elements that cause mechanical weathering?

Mechanical weathering is caused when any of the following factors act physically on a rock to break it down: water, ice, salt/mineral crystals, the release of pressure, extreme temperatures, wind, and even the actions of plants and animals.

What are 4 examples of mechanical weathering?

What are 4 examples of mechanical weathering? Some examples of mechanical weathering are exfoliation, water and salt crystal expansion, thermal expansion, abrasion by wind and water erosion, and even some types of actions by living things (like plant roots or a burrowing mole).

What are 5 mechanical weathering agents?

Agents of mechanical weathering include ice, wind, water, gravity, plants, and even, yes, animals [us]!

Animal Activity.
Thermal Expansion.
Frost action.
Exfoliaton.

What are the 6 types of weathering?

There are 6 common ways in which physical weathering happens.
