Do gravity and ice cause mechanical weathering?

Yes, gravity can cause mechanical weathering through processes like mass wasting, where gravity causes rocks and debris to move downhill. Ice can also cause mechanical weathering through frost wedging, where repeated freezing and thawing of water in cracks and crevices causes rocks to break apart.


Which of the following is NOT a cause of mechanical weathering?

Temperature changes, such as freezing and thawing, is NOT a cause of mechanical weathering.


What is an example of mechanical weathering by gravity?

An example of mechanical weathering by gravity is a rock falling down a steep cliff and breaking into smaller pieces as it hits the ground. This process is called rockfall and is a common way in which gravity causes mechanical weathering by physically breaking apart rocks.


Do plant roots cause mechanical weathering?

Yes, plant roots can cause mechanical weathering by exerting pressure on rocks as they grow and expand, leading to the breakdown of the rock material. This process is known as root wedging and can contribute to the disintegration of rocks over time.


What are the forces that cause weathering?

Weathering is primarily caused by three main forces: mechanical weathering, chemical weathering, and biological weathering. Mechanical weathering occurs when rocks are broken down into smaller pieces through physical processes such as freezing and thawing. Chemical weathering involves the breakdown of rocks through chemical reactions, such as oxidation and hydrolysis. Biological weathering is caused by living organisms, which can break down rocks by their growth, burrowing, or through chemical processes.
