|
|
The oldest fossils are found closer to the surface of Earth.
|
|
|
The oldest fossils are found deeper in the ground.
|
|
|
Fossil age cannot be determined by examining rock layers because too much of the Earth has been disturbed by catastrophic events (such as earthquakes)
|
|
|
Fossils found in stone are more reliable than those encased in amber

Detailed explanation-1: -law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
Detailed explanation-2: -The Law of Superposition, which states that in an undisturbed horizontal sequence of rocks, the oldest rock layers will be on the bottom, with successively younger rocks on top of these, helps geologists correlate rock layers around the world.
Detailed explanation-3: -The law of superposition is one of the principles of geology scientists use to determine the relative ages of rock strata, or layers. This principle states that layers of rock are superimposed, or laid down one on top of another. The oldest rock strata will be on the bottom and the youngest at the top.
Detailed explanation-4: -Scientists can read layers of rock knowing that each layer of sediment is deposited on top of older layers. The law of superposition states that each rock layer or strata is older than the one above it. So, the relative age of the rock or fossil is older if it is located farther down in the rock layers.
Detailed explanation-5: -RELATIVE AGE OF ROCKS The main law is the law of superposition. This law states that deeper rock layers are older than layers closer to the surface. An unconformity is a gap in rock layers. They occur where older rock layers eroded away completely before new rock layers were deposited.
