How do layers change into rocks?
Sediment layers are squeezed from above by the weight of overlying sediment, causing compaction. Compaction squeezes out air and water between the sediment particles. Minerals form as the air and water is squeezed out, cementing the particles together, and forming sedimentary rock.

The process in which the weight of sediment above squashes together the sediments below?
?
Does metamorphic rock form when sediment is squeezed by the weight of the rock above it?
medamorphic rock
Which of the following conditions are necessary to cause loose sediment to become sedimentary rock?
There are no following conditions. Pressure will make loose sediment into rock, the pressure may derive from the weight of water or other rocks above the sediment.
Is created when layers of material are hardened by the intense weight of more materials piled above?
sedimentary rock
What is the clear liquid above the sediment called?
The fluid above the sediment after centrifugation is called the supernatant.
Earth's core is under great pressure due to?
The pressure exists from the massive amount of material and weight from the layers above.
How is weathering related to the formation of sedimentary rocks?
Weathering is the breaking down of existing rock into smaller pieces that are transported by erosion to a place of deposition, which can lead to compaction and cementation--two processes necessary in the formation of sedimentary rock.
What is the fluid left above sediment after centrifugation called?
Centrifugation is the process of separating two immiscible liquids. The fluid which is above the sediment after centrifugation, is called the supernatant.
How does density change between the different layers of earth?
The deeper you get into the earth, the more weight you have above you. This results in pressure that increases the density of the material below.
Describe two ways that fossils can form?
By fossilisation and permineralisation. Fossilisation is caused by layers upon layers of sediment burying the bones. As the layers of sediment above the buried bones increases, so does the pressure on the layers of sediment lower down. The pressure becomes so great that the bones and the sedimentary rock fuse. Permineralisation occurs when mineral rich water trickles in through the sedimentary rock reaching the dinosaur bones. The minerals fill in the cracks and spaces within the bone. Sometimes the calcium in the bones may be replaced with these minerals. The new minerals in the bone make them even harder and more likely to be preserved.
