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: -Erosion and weathering transform boulders and even mountains into sediments, such as sand or mud. Dissolution is a form of weathering-chemical weathering. With this process, water that is slightly acidic slowly wears away stone. These three processes create the raw materials for new, sedimentary rocks.

Detailed explanation-3: -Horizon C is least affected by the soil formation process. Bedrock lies below the soil layers. Horizon O forms from organic material. Horizon C is least affected by the soil formation process.

Detailed explanation-4: -This is called chemical weathering. The minerals dissolved in the water precipitate and create deposits as the water evaporates, forming sedimentary rocks over the years. So, chemical weathering is an essential part of the formation of sedimentary rocks as it supplies the materials required for the process.
