Question

Distinguish between the following.
1. physical weathering and chemical weathering
2. weathering and erosion​

Answer 1

Answer:

1. Physical, or mechanical, weathering happens when rock is broken through the force of another substance on the rock such as ice, running water, wind, or plant growth. Chemical weathering occurs when reactions between rock and another substance dissolve the rock, causing parts of it to fall away.

2. While weathering and erosion are similar processes, they are not synonymous. Weathering involves the breakdown of rocks and minerals on Earth, whereas erosion involves the removal of soil and rock materials.
