Well, with the layers of rock forming over-time thus helping to create structure, to hold the weight of the earth... When the universe was created, the planets were hot massive balls of lava. But, since it is cool in the universe, the planets cooled down on the outside, leaving the lava as the core. Then, as you progress outward from the middle, the layers get cooler. They are different temperatures and the rock is in different conditions.

What thing has layers?
The Earth's crust has layers, the atmosphere has layers, and certain types of cake have layers.
How do scientist learn about changes on earth from rocks?
Scientists study layers of rocks to learn about the earth and how it has changed. They know that if layers are undisturbed, the oldest rocks are on the bottom and the youngest rocks are on top. They know how old each layer is in relation to the other layers.
How were rocks used in the building of some types of castle?
Two layers of rocks (gaps in rocks filled with mortar) and earth in between the two layers of rocks.
Is the rocks layers near the surface of earth younger than rock layers further from the surface?
Yes.
Which two layers of the earth are made up of rocks?
Crust and mantle
Does ganymede have rocks?
Yes, Ganymede does have rocks, but their exact composition is unknown. It also appears to have separate layers, similar to Earth.
What part of the earth is compose of rocks and solids?
The crust and part of the mantle is made of rocks and solids. The other layers under the earth are mostly composed of molten lava or semi-molten rocks.
What is the law of superposition and how does it help scientists learn about earth's past?
The law of superposition states that in a sequence of undisturbed rock layers, the oldest layers are at the bottom and the youngest layers are at the top. By studying the order of rock layers and the fossils within them, scientists can determine the relative ages of the rocks and reconstruct the Earth's past environments and history.
What earth foces cause metamorphic rocks to form?
Pressure through layers of crust
What are horizontal layers of rocks?
Horizontal layers of rocks are rock layers that are parallel to the Earth's surface. These layers are typically formed over time through sedimentary processes, such as deposition of sediment in water or air. The horizontal orientation of these layers indicates the original horizontal position in which they were deposited.
What are the layers found in sedimentary rocks called?
The layers found in sedimentary rocks are called strata. These are horizontal layers of sediment that have been deposited over time and then compacted and cemented together to form rock. Each layer represents a different time period in Earth's history.
What are the 2 characteristics of sedimentary rocks that reveal the past history of the earth?
Presence of fossils and stratification of the rocks structure into different layers.
