Question

12. Which of the following is an agent of mechanical weathering?

​

Answer 1

Answer:

Agents of mechanical weathering include ice, wind, water, gravity, plants, and  animals that include us!

Explanation:

you didn't give the multiple choice cuz the question says "which of the following" but the following is missing. So here here are some weathering agents. :)

Hope this helps!

Answer 2

Answer:

Mechanical weathering frequently involves the presence of water, whether it is in liquid or solid form.

Explanation:

• Two significant mechanical weathering processes are ice wedging and abrasion. Through the formation of fresh minerals that are stable at the Earth's surface, chemical weathering decomposes rocks. Chemical weathering is largely influenced by oxygen, carbon dioxide, and water.
• Frost and salt wedging, unloading and exfoliation, water and wind abrasion, impacts and collisions, and biological processes are a few examples of mechanical weathering. All of these techniques reduce rocks to smaller pieces without altering their physical makeup.
• Moving water, the wind, and gravity are three physical weathering forces that can result in abrasion. Also Other rocks on the surface of the earth may become scratched by rocks suspended in glacial ice. Furthermore, boulders in flowing water may become rounded and smooth.

Thus, rocks break down into smaller pieces mechanically during physical weathering, sometimes referred to as mechanical weathering.
