gravity
i font know
Its density.
The scientific term is 'strata'.
soil
original horizontality
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.
The chronological order of rock layers from oldest to youngest
Different densitys
because there are different pressures in the air.
Gravity and Centrifugal force causes the layers to settle, in a similar way to why a centrifuge causes blood in a test tube to split into different groups of material like platelets ect.
The scientific term is 'strata'.
what causes a rock to break into many layers. DOES WATER
Original horizonality
Minerals cause the layers - each mineral has a certain color (and hardness).
Compressive stress causes the "crumpling" and folding of rock layers.
soil
The layers of the earth extend for miles. It would be possible to list those distances in scientific notation.
Younger layers of sedimentary rock are deposited on older layers
Earthquakes
