Question

Explain the formation of sedimentary rocks on the basis of agents of formation.

Answer 1

There are five main types of rocks on the basis of agents of formation:

1. Riverine Rocks These are formed by the sediments deposited by running water or a river.
2. Lacustrine Rocks These are formed by the deposition of silt, etc., on the bed of lakes.
3. Glacial Rocks These are formed by the debris carried off and deposited by glaciers.
4. Aeolian Rocks These are formed by the deposition of sand accumulation by the wind.
5. Marine Rocks These are formed by the deposition of sediments at the ocean floor. These types are calcareous and carbonaceous sedimentary rocks.
