the weight of the rocks above you...
Earths crust extend deeper below the continents than below the oceans basins (or at least this is what I think).
temperature gets hotter
Because the density of the force increases.
Because the density of the force increases.
The oceans flow to the places where the crust is the lowest. Gravity causes them to flow downward. The mantle, below the crust, is at the same depth everywhere, so if the crust is lower, it is because it is thinner.
The pressure increases as you go deeper below the Earth's crust due to the weight of the overlying rock and other materials. As you move deeper into the Earth, the layers above exert a greater force, causing the pressure to rise. This phenomenon is known as lithostatic pressure.
Isostasy is the flotational balance achieved between rocks of the crust lithosphere and deeper mantle. This balance is maintained as lighter rocks of the crust "float" on the denser rocks of the mantle below.
As you go deeper below the Earth's crust, pressure increases due to the weight of the overlying rock layers. This is known as lithostatic pressure, which results from the gravitational force acting on the mass of rock above. Additionally, the temperature also rises with depth, contributing to changes in material properties, but the primary cause of increased pressure is the accumulation of rock mass. This pressure can lead to geological phenomena such as the formation of minerals and the behavior of magma.
Erosion and wearing away of a mountain decreases the weight of the crust, causing it to rise higher and extend deeper into the asthenosphere. This process is known as isostatic rebound. As material is removed from the surface through erosion, the crust floats higher on the denser asthenosphere below, causing it to sink deeper.
Nobody has gone deeper than the upper part of the crust.
Isostatic adjustment will cause the crust beneath the volcanic mountain range to gradually sink due to the weight of the mountains. This sinking is a response to the added load of the mountains and helps to maintain equilibrium in the Earth's crust.
It is in a solid state of matter. Unlike the deeper rocks of the mantle, crustal rocks do not readily deform, and heating from below will cause the lowest layers to melt into magma...which being less dense tends to flow upward.
