Question

what will happen if weathering and soil erosion will not occur

Answer 1

The most common cause of mechanical weathering is pressure built up by water freezing within the rocks. This type of weathering can also be caused by earthquakes or shifting of the earth's plates. Temperature changes or salt buildup causing pressure within the rocks can also cause particles of the rocks to break off.

Answer 2

Hey there,
Here is your answer ⤵⤵⤵

Weathering is the process of breaking up, weakening and disintegration of the rock which forms the surface of the ground and is exposed to the weather. It is caused due to the forces of weather like changes in temperature, and action of rain and frost.

The significance of weathering is as follows:

1. It helps in the formation of soil. It breaks down the rock into smaller fragments. The depth of the soil depends on the extent to which the rocks have been weathered.

2. It helps to produce other natural resources like clay and bauxite. Clay is used for making bricks and pottery. Aluminium is extracted from bauxite.

3. Weathering weakens the rocks so it becomes easier to carry out mining and quarrying work.

4. It modifies the original landforms. This influences the kind of human activities which can be carried out in the region. So the process of weathering plays an important role in supporting life.

5. Erosion and weathering lead to the formation of fascinating landforms called tors. They act as a tourist attraction.

If there is no weathering all these benefits may not be available and the survival of human beings may become difficult. There may be no change in the Earth's surface.
