Bedrock Definition
Bedrock is a hard rock. It provides support to various materials such as soil and gravel. Sand and other sediments on the ocean floor are also supported by bedrock.
Description
Solid rock that is closely linked together is called bedrock. Frequently, unconsolidated rock made up of loose grains makes up the surface material. Near the Earth’s crustal base, bedrock can be found hundreds of meters below the surface. The term “crag” refers to the top of the bedrock. Saprolite may be present on the bedrock’s uppermost portion.
The bedrock known as saprolite is severely eroded or weathered. Actually, saprolite goes through a process of chemical weathering. Saprolite is therefore not only a hard rock but also has a unique chemical make-up. Rock minerals react with moving water and ice, altering their chemical makeup. Above the saprolite, there can be a layer of soil, sand, or sediment. These are typically the younger, less-consolidated rocks that are more prevalent.

What Is Weathering Of Bedrock?
Bedrock that has been exposed to the elements undergoes weathering, which can be either chemical or physical in nature and modifies the structure of the rock to make it more erosive. At its upper border, bedrock may also undergo subsurface weathering, resulting in saprolite.
