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: -When rocks are exposed to acidic substances the acids react with minerals inside the rocks, weakening the structure of the rock and causing it to break down more quickly. For example, when carbon dioxide and water mix to form carbonic acid, this acid can get inside of rocks and cause chemical weathering.

Detailed explanation-3: -Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

Detailed explanation-4: -The primary agents in chemical weathering are water, oxygen, and acids. These react with surface rocks to form new minerals that are stable in, or in equilibrium with, the physical and chemical conditions present at the earth’s surface.
