According to the Law of Superposition, in an undisturbed column of rock layers, the oldest layers are at the bottom, the youngest at the top. Logically, there must be a first layer, without which the succeeding layer would not rest. Deposits of sediments that appear in sedimentary rock are laid down over long periods of time and often appear layered, like the pages of a book that starts at a certain time and goes back further in time with each page.

The deeper you go, the more the rocks above press down on them.

Because the weight of the rock above is pressing down towards the Earth's centre. Basically - the closer you are to the centre of the Earth - the more rock is pressing down.

Which characteristic of rocks tends to increase as the rocks are metamorphosed?

Density


Does the soil porosity increase as the depth increases?

Bulk density generally increases with soil depth due to increasing pressure from the soil column above. Porosity is inversely related to bulk density, thus porosity should decrease as soil depth increases.


How would elevation of mountains be different if rocks were denser?

By definition, increasing the density of rocks in the mountains would decrease the elevation of mountains. However one could try to reason that increasing the density would cause more increase in uplift and and increase in elevation.

As the amount of iron in an ignous rock becomes greater its density will?

As the iron content increases, it's density will also increase. Iron and magnesium rich rocks are known as mafic rocks. Please see the related link.


Why is density of water more in deep water?

The density of water increases with depth due to the increase in pressure. As water molecules are packed closer together under high pressure, the density of water increases. Therefore, in deep water where the pressure is higher, the density of water is also higher.


What is the relationship between the density of earth materials and depth below the surface of the earth?

As the depth increases, the density increases also.


What is the relationship between the density of the earths materials and depth below the surface of the earth?

As the depth increases, the density increases also.


It so happens that an actual increase in weight is found in even the deepest mine shafts what does this tell us about how the Earth's density changes with depth?

The Earth's core is about 7 times the density of the surface rock. That means, a person in a deep mineshaft is getting closer to more mass. Therefore, density is relative to the depth of the earth by the correlation this has on a person's weight.


Where does metamorphism take place?

Most metamorphism takes place deep underground, where high heat and pressure change the rocks, since both increase with depth.


What happens to density of rocks as it cools?

the density increases
