Question

Which of the following describes weathering?

• A. The breaking down of rocks, soil and minerals by external agents(wind, rivers etc) is called weathering.
• B. The combination of rocks, soil and minerals is called weathering.
• C. Change in climate is called weathering.
• D. When rocks melt due to intense heat, it is called weathering.

Answer 1

The correct option is A

The breaking down of rocks, soil and minerals by external agents(wind, rivers etc) is called weathering.

Weathering is the breaking down or dissolving of rocks and minerals on Earth's surface. Water, ice, acids, salt, plants, animals, and changes in temperature are all agents of weathering.Once the rock has been broken down, a process called erosion transports the bits of rock and minerals away. No rock on Earth's surface is hard enough to resist weathering. Together, the processes of weathering and erosion lead to the formation of soil and the only thing it requires is time.
