How does the process of weathering and erosion begin?

Answer 1

Processes of erosion and weathering occur as long as the following are secured:

• There is heat from the sun (for the water cycle to take place, as well as for wind to be possible
• There is material above the surface of the oceans (for the processes to take place on, otherwise the processes will either be slow or non-existent, especially if there was no moon)
• There must be life for some types of weathering to happen

I hope this answers your question.

Answer 2

Weathering begins when physical or chemical elements such as wind, water, ice, and chemicals break down rocks into smaller pieces. Erosion then occurs as these smaller pieces are transported and deposited by natural forces like wind, water, or ice. This continuous cycle of weathering and erosion gradually shapes and alters the Earth's surface.
