* Rock can be formed from mechanical and chemical weathering. * Flash flooding can cause alterations in the layers and unique formations can be created. * The sedimentary rock which makes up 5% of the earths rocky layers, compact under pressure and release connate fluids which eventually form solid rock (Lithification).

The water and other rocks on top put pressure onto the rocks and squeeze them together to form a rock layer. This happens again and again over millions of years until there are lots of layers of rock. The layers get twisted and folded by the movements in the magma in the mantle below.

What kind of scientists studies how layers of rock formed and changed over time?
One scientist who attempted to explain how rock layers form and change over time was James Hutton.
Where are the oldest layers of a sandstone rock located?
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
What is the rock cycle explain in kids' explanation?
Magma from the earth travels to the surface It hardens and makes mountains. Water breaks the mountains down over a long time The small bits of rock travel down rivers and go into the sea Over time, layers of rock form, called sedimentary rocks During this time, at depth, the pressure is high and so rocks get bent and form metamorphic rocks.
Why are earth rock layers different?
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.
Broken pieces of what types of rock are deposited into layers and cemented together to form?
All types of rock can fragment, and with time, the fragments become deposited in layers which can become buried, then through heat and pressure become cemented together to form a material known as Cliche, which in turn can fuse together through heat and pressure to become what is known as Conglomerate.
Can metamorphic rock form from sedimentary rocks?
Yes. A sedimentary rock, over time, can become buried under layers of newer rock. The heat and pressure from being in between layers of old and new rock, will change it from sedimentary to metamorphic.
Why does sedimentary rock from in layers?
due to the compaction over time
Which process changed the shape of the rock layers over time?
an erosion

What can you find within layers of sedimentary rock?
As sedimentary rock is deposited at over time, you can find fossils in it.
Why does sedimentary rock form in horizontal layers?
Sedimentary rocks are types of rock that are formed by the deposit of material at the Earth's surface and within bodies of water. The horizontal layering happens because it has forms with the passing of time over thousands if not millions of years.
Where are the oldest layers of a sandstone rock located?
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
How do rock fossils form?
over time.
How does the deposition of rock materials produce layers of sedimentary rock over time?
Through series of processes combinely known as Diagnesis.
What kinds of rock can form sedimentary rock?
anything can form sedimentary rock; it is caused by the erosion of sediment over time

How are index fossils useful to geologist?
Index fossils provide a reference of time throughout rock layers. In order to be a good index fossil, the life form must have lived for a short and specific amount of time and must have existed over a large area. Index fossils serve as a reference to geologists in correlating rock layers. They can match up (or correlate) the index fossils which helps them match up (or correlate) the rock layers.
