GEOLOGY

Detailed explanation-1: -The broken pieces of rocks are carried away by wind, glaciers and rivers. This process is called as erosion. The eroded material is finally deposited as pebbles, sand or mud. Therefore, the sequence of processes is: weathering, erosion, deposition.

Detailed explanation-2: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away.

Detailed explanation-3: -Expert-Verified Answer. The correct sequence of layers in a soil profile is topsoil, subsoil, and bedrock, respectively. Soil is made of different layers which are collectively known as horizons.

Detailed explanation-4: -Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.

Detailed explanation-5: -The Important processes of chemical weathering are solution, carbonation, hydration, oxidation and reduction. These processes act on the rocks to decompose, dissolve or reduce them to a fine clastic state through chemical reactions by oxygen, surface and/or soil water and other acids.
