Question

5. What are sedimentary rocks? Explain how they are formed.​

Answer 1

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.

Answer 2

Explanation:

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms.

They form from deposits that accumulate on the Earth's surface.

Sedimentary rocks often have distinctive layering or bedding.

Sedimentary rocks are produced by the weathering of preexisting rocks and the subsequent transportation and deposition of the weathering products.

Weathering refers to the various processes of physical disintegration and chemical decomposition that occur when rocks at the Earth’s surface are exposed to the atmosphere (mainly in the form of rainfall) and the hydrosphere.
