GENERAL GEOLOGY

Detailed explanation-1: -Common sedimentary rocks include sandstone, limestone, and shale. These rocks often start as sediments carried in rivers and deposited in lakes and oceans.

Detailed explanation-2: -Chemical sedimentary rocks can be found in many places, from the ocean to deserts to caves. For instance, most limestone forms at the bottom of the ocean from the precipitation of calcium carbonate and the remains of marine animals with shells.

Detailed explanation-3: -Graded Bedding At the bottom of the bed are mainly coarse particles which get progressively smaller as you move vertically up the bed. Graded beds generally represent depositional environments in which transport energy decreases over time, like the changing water velocity in a river.

Detailed explanation-4: -Sedimentary rocks are formed by the deposition and subsequent cementation of the material at the Earth’s surface within the bodies of water.

Detailed explanation-5: -Sediments can also form by the accumulation of shells of dead organism and can consist of mineral and/or fossil. Deepest areas of ocean floor which is far from land are dominated by abyssal clay which is called “red clay” and consists of smaller sediments which are carried away by the currents and winds.
