OBJECTIVE FORESTRY

Detailed explanation-1: -Bedrock is the hard, solid rock beneath surface materials such as soil and gravel. Bedrock also underlies sand and other sediments on the ocean floor. Bedrock is consolidated rock, meaning it is solid and tightly bound. Overlying material is often unconsolidated rock, which is made up of loose particles.

Detailed explanation-2: -Bedrock is the deepest layer that contains nothing but hard, solid rock in it. The bedrock formed the soil above it. It will wait here until erosion or an earth-quake exposes it to the surface.

Detailed explanation-3: -At the center of the Earth is the molten metal core, surrounded by the rocky mantle and then the outer crust. This outer crust is mostly comprised of rock, with a thin layer of soil, sand and loose material on top of it. The point where the rock is still a solid mass is called the bedrock.

Detailed explanation-4: -Bedrock can be any of the three rock types; Sedimentary, Metamorphic, and Igneous, in origin. Further rock layers below the bedrock are referred to as rockhead. The depth of regolith can range from nonexistent to extremely deep, depending on location.

Detailed explanation-5: -Bedrock, or ledge as it is sometimes called, underlies all parts of the Earth’s surface. It is usually buried by soil and vegetation, but in places such as mountain tops, stream banks, and road cuts it is often visible at the ground surface.
