They are physical features that allow the geologists to take them apart in order for them to figure out the history of the civilization at hand.
Geologist must use their knowledge of the events that disturb or remove rock-layer sequences to help piece together the history of Earth as told by the rock record.
The bottom layer of a sedimentary rock is called the basal layer. This layer is considered the coarsest in the rock.
Yes
The lithosphere is the physical layer of hard brittle rock. The remainder of the mantle that is not contained in the lithosphere is the layer of ductile rock.
rock layering is where you have one layer of old rock them a newer layer then an other newer layer.

The bottom layer of rock in a geologic sequence is usually called the basement layer.
Unconformity
An upwards arching layer of rock is known as an anticline.
Superposition is the theory that the rock layer that is on top is the youngest and the layer of rock on the bottom is the oldest.
The layer that is partly weathered rock is called the saprolite layer. This layer is between the unaltered rock below and the soil layer above. Through weathering processes, the saprolite becomes broken down and forms the basis for soil formation.
