The depth at which rocks begin to melt, known as the melting zone, typically occurs around 25 to 30 kilometers (15 to 19 miles) beneath the Earth's surface, depending on factors such as temperature and pressure conditions. This zone varies with geological settings; for example, in regions with high geothermal gradients, melting can occur at shallower depths. Additionally, the presence of water and other volatiles can lower the melting point of rocks, facilitating melting at greater depths.
What else can I help you with?
Rock can melt at a depth of about below Earth's surface.?
Rock can melt from 600- 1200C, depending on the type of rock, but this is assuming 1atm pressure. Under the earth, there are higher pressures, increasing the melting point. So although the rock should have melted by the mantle, which is 500-4000C and at a depth 35-2900km below the surface, it is a silly putty-like plastic solid rather than a liquid. The earth only becomes liquid at a depth of 2900km in the earth's outer core, but that is made of metal, not rock, so essentially, none of it.
What depth do rocks melt?
Rocks typically start to melt at depths of 50-100 kilometers beneath the Earth's surface, where temperatures are high enough to exceed their melting point. This depth can vary depending on factors such as the rock type and the presence of water or other melting point-lowering substances.
Can lava melt rock in the mountain?
Underground molten rock, called magma, does melt some of the surrounding rock.
What rock is formed when sandstone is exposed to heat and pressure?
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
When snow begins to melt what does it turn in to?
water...and then disolves into the ground
What rock can melt at a depth of about below earths surface?
50km
Does magma form when rock begins to melt?
Yes. Magma is underground molten rock.
Once rock reaches a depth of about it may melt?
Once rock reaches a depth of about 100 kilometers, it may start to melt due to the high temperatures found in Earth's mantle. This molten rock, or magma, can then rise to the surface and erupt as lava, creating volcanic activity.
Would new igneous rock be formed if Earths temperature did not increase with depth?
No, new igneous rock forms from the melting of pre-existing rock due to an increase in temperature with depth. If Earth's temperature did not increase with depth, there would not be enough heat to melt rocks and form new igneous rock.
Rock can melt at a depth of about what degree below Earth's surface?
Rock can start to melt at a depth of around 50-100 kilometers below Earth's surface due to high temperatures and pressure. This process can lead to the formation of magma, which can then rise to the surface and result in volcanic activity.
How does the addition to fluid relate to the formation of magma?
When the fluids enter the already hot mantle rock, the melting temperature of the hot rock decreases. As a result, the rock begins to melt.

Above what temperature centigrade does ice melt?
Ice begins to melt at Zero degrees...
Can anything melt a rock?
Substantial heat, whether produced by humans or naturally occurring, can melt rock.
If a rock gets a hot enough it will?
it will melt
