To what depth below Earth's surface do you have to go before the pressure and temperature cause rocks to melt?

At depths between 50 to 200 km below Earth's surface, temperatures and friction, along with the presence of water, could cause melting of subducting crustal material. Rising currents of mantle rock could melt from decompression at shallower depths.

The melting point of rocks decreases with increasing pressure, so the depth at which rocks melt below the Earth's surface varies depending on factors such as the composition of the rocks and the geothermal gradient of the region. Generally, rocks start to melt at depths of 10-50 kilometers below the surface in the Earth's crust.

How much does gas expand when heated?
gases obey the universal gas law of (gas pressure) * (gas volume) / (gas temperature) being a constant. If the pressure is kept unchanged before and after the heating occurs, doubling the temperature will increase the volume to two times the volume before.
Why pressure drops before storm comes?
Before a storm arrives, the pressure drops because the storm system's low-pressure center causes the air above it to rise, creating an area of lower pressure at the surface. As the storm approaches, the drop in pressure can be felt because our bodies are sensitive to changes in atmospheric pressure. This drop in pressure is often associated with unsettled weather and precipitation that accompany the storm.
When scientists record the volume of a gas why do they also record the temperture and the pressure?
Temperature and pressure can affect the volume of a gas through the ideal gas law, which states that pressure, volume, and temperature are interrelated. By recording all three variables, scientists can accurately calculate the amount of gas present and make comparisons between different conditions or experiments.
What is pressurized water reactor power plant.?
It means that:* There is water, and * It is under higher pressure than normal, i.e., more than 1 atmosphere (or bar) of pressure. At higher pressures, water can achieve a higher temperature (i.e., higher than 100 degrees Celsius) before it boils.
A sample of a gas has a volume of 2.0 liters at a pressure of 1.0 atmosphere When the volume increases to 4.0 liters at constant temperature the pressure will be?
For this you would use Boyle's Law, P1V1 = P2V2. The first pressure and volume variables are before the change, while the second set are after the change. In this case, the volume is being changed and the pressure has to be solved for. P1 = 1.00 ATM V1 = 2.0 L P2 = Unknown V2 = 4.00 L P1V1 = P2V2 1.00(2.0)=4.00P P= .5 ATM
What depth below earths surface do you have to go before the pressure and temperature cause rocks to melt?
At depths of 50 to 200 km below Earth's surface rocks will melt.
What burns up before they hit earths surface?
Meteors!
What is the name for lava before it leaves the volcano?
its magma before it reaches earths surface. lava is when its at earths surface
What burns up before it hit the earths surface meteor or asteroid?
A meteor.
What must occur before precipitation can fall on earths surface.?
Evaporation and condensation
Where does magma form before it moves toward the earths surface?
in the mantle above the slab
What is the temperature of ice water before the ice is completely melted?
It depends slightly on the atmospheric pressure. At standard pressure the answer is 0 C or 32 F
Where does magma form before it moves toward Earth's surface?
from rocks being melted in the earths core, it then gets pushed up and the pressurre builds, the a volcanic erupiton takes place due to the pressure from the outer core/mantle, strange but true

What is the pressure inside of a container when nitrogen gas is added?
The pressure inside of a container when nitrogen gas is added depends on:what the pressure was before the gas was addedhow big the container ishow much nitrogen gas is addedthe temperature of the gas before it is addedthe temperature of the container and its contents
When magma hardens and comes to the earths surface what is it called?
If the magma has hardened before being exposed at the surface it would be considered an intrusive igneous rock. It is hardens at or near the surface, it would be called extrusive igneous rock.
What is the temperature of steam in a closed heat pipe before it condensed and turned back into water?
That would depend on the pressure as there is something called pressure /temperature relationship @ 1 PSI the steam is 212 deg That would depend on the pressure as there is something called pressure /temperature relationship @ 1 PSI the steam is 212 deg
