GENERAL GEOLOGY

Detailed explanation-1: -High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions.

Detailed explanation-2: -A cold, dry climate will produce the lowest rate of weathering. A warm, wet climate will produce the highest rate of weathering.

Detailed explanation-3: -– Weathering depends on water and temperature. – Mechanical weathering occurs fastest in areas that have a lot of temperature changes. – Chemical weathering is fastest where the climate is warm and wet, near the equator.

Detailed explanation-4: -And a warmer Earth increases the rate of chemical weathering both by causing more rainfall and by speeding up the chemical reactions between rainwater and rock.

Detailed explanation-5: -The chief agents of chemical weathering are air and water. By the action of this two agents, the minerals in rock undergo chemical change and form a new chemical substance. Chemical weathering is more dominant in the area of humid climate.
