50km
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.
The melting point of rocks and minerals generally increases with depth below the Earth's surface due to the increase in pressure. The average increase is about 25-30°C per kilometer in depth. This means that at greater depths, higher temperatures are needed to melt rocks and minerals.
At depths of about 50 to 200 km below Earth's surface Rocks melt at depths at 50 and 200 km below the Earth's surface.
Melted rock below Earth's surface is known as magma. Magma forms when rocks in the Earth's mantle melt due to high temperatures and pressure. As magma rises towards the surface, it can eventually erupt as lava through a volcano.
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.
At depths of 50 to 200 km below Earth's surface rocks will melt.

extrusive- when melted rock material coools on earths surface instursive-when the melt cools below earths surface
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 and minerals generally increases with depth below the Earth's surface due to the increase in pressure. The average increase is about 25-30°C per kilometer in depth. This means that at greater depths, higher temperatures are needed to melt rocks and minerals.
At depths of about 50 to 200 km below Earth's surface Rocks melt at depths at 50 and 200 km below the 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.

No! First of all, magma is below the surface and it is molten material.
it will over flood the earths surface with melt water of the ice berg and detroy land under sea level
Volcanoes do not cause rocks to melt, they are just the exit where melted rock come to the earths surface.
At convergent boundaries some mantle material can melt and rise through the crust, forming volcanoes.
