Pressure does not change the temperature of rocks, but it does change the melting point. A rock that is under a lot of pressure, even if it is very hot, will stay solid, even if that same rock at the same temperature under lower pressure would be melted. This happens because intense pressure can hold the structure of the minerals together more easily, in a more solid form.
So, with an increase in pressure, the melting point of a rock also increases.

Does a volcano make magma?
A volcano does not make magma. The magma is created underground by melted rocks due to the earth's core temperature. When na big amount of magma is created, the volcano feels pressure, and then it errupts magma, but it does not make it.
Why does magma sometimes push through earth's surface and make a volcano?
because of pressure
How does a volcanic mountain increase in size?
The size of volcanoes increase as more magma comes up form the mantle. Some magma comes to the surface forming layers of ash and lava, (layers=strata that is why this kind of volcanoes are called Stratovolcanoes). some lava often will not come up to the surface but will still make the volcano larger. Lava that have not reached the surface will cool down slower allowing larger crystals to form.
Where is magma found in a volcano?
A volcano does not make magma, magma is the motlen rock underneath The Earth's crust. A volcano is an opening in the crust that allows the magma to be released to the surface. Magma is made by pressure and heat on rocks deep within The Earth.
How can I increase the water pressure in my shower to make it stronger?
To increase water pressure in your shower, you can try cleaning the showerhead, checking for any clogs in the pipes, adjusting the pressure regulator, or installing a water pressure booster pump.
What 2 things can make the pressure of gas rise?
1) Increase in heat 2)Decrease in volume
How can you make a volcano explode?
A volcano can explode when pressure builds up inside it due to trapped gases and magma. This pressure can be released explosively when the volcano erupts, causing an explosion.
Does vigorous exercise increase blood pressure?
The blood pressure will increase during physical training, but it won't make you a person with high blood pressure permanently.
What are some signs that a volcano is active?
The sighs are like kind of like earthquakes a Little only if you live near the the volcano if you live near and it seems active make sure you get a bag ready in case of the magma goes to your home and my harm your loved ones and anther thing you can go is put cold water on the magma it will cool off so that you can walk safely without hurting your feet
How do you increase pressure and decrease pressure?
Pressure is given by the equation P = F/A, where F is force and A is the area it's applied over. For a solid or liquid, you can increase pressure just by pushing harder on it. For a gas, pressure is approximately given by P = (n*R*T)/V, where n is how much gas you have in moles, T is the temperature in kelvin, V is the volume of the container, and R is a constant. So to increase pressure, either increase the amount of gas, increase the temperature, or decrease the volume of the container.
What conditions make for a violent volcanic eruption?
Magma with high silica content
What size crystal do magma make?
it depends on if it is intrusive or extrusive (intrusive is below the earth and extrusive is at or above the earth) intrusive has a bigger crystal because it takes time to cool down.
