Rock layers are different and unique to each other due to the fact that each layer represents a time period. They are formed when rock, sediment, and minerals settle into one place for a long time and harden when another layer goes over it. Reading rock layers allow geologists to determine how much time has passed. They even sometimes tell of the history of the earth and all of the disasters that have occurred in each era.

How are earths layers different?
They are different because different minerals can be found at different layers. Also, the layers closer to the core of the earth will become more hot, causing melted rock (magma) to form.
How is folding different from tilting?
Folding happens when rock layers bend and buckle under pressure. Tilting happens when forces from inside Earth cause rock layers to become slanted.
How many layers are there in the earth's crust?
The crust alone contains millions of different layers of sedimentary rock. For the layers of the Earth, some of which are rock and some of which are not, see the related link below.
Why are layers of rocks different thicknesses?
The layers of rock are different thicknesses because of the way the sediments are formed and squashed together
How does earthquake waves determine the different layers of the earth?
how earthquakes helped in determining the different layers of earth
What can biologists learn from the different layers of rock in the Earth?
cool

How can ingneous rock disturb sedimentary rock layers?
Molten Rock from with in earth can force its way up through the layers above it cooling and forming igneous rock.
What kind of rock is made up of layers?
Sedimentary Rock is made up of layers of different rocks.
