Amazing Fossils
Law of superposition
The law of superposition is a law, saying that in any sequence of rocks deposited in layers, the youngest layer is on top and the oldest is on is in the bottom. Each layer being younger than the one beneath it and older than the one above it.
what can fossils tell us about Earth?
Fossils provide us with information about the history of our world. Also they tell us about how plants and animals lived in the past. Fossils records can provided us information about how life had existed on Earth long ago. Also how diverse plants and animals are linked to each other.
Are all fossils the same?

The rock cycle
The rock cycle is a continuous process by which rocks are created, changed from one form to another, destroyed, and then formed again. The rock cycle goes through many changes like how metamorphic rocks change into sediments by weathering and erosion. Or how Sedimentary rock is changed into Metamorphic rock by heat heat and pressure. All of this in the picture above is what the rocks go through during the rock cycle.
So how are minerals identify? and what are the two ways that minerals form?
The way how you identify minerals is by knowing that each mineral has it`s has characteristic properties that can be used to identify it.
