The answer is the asthenosphere, the crust is part of the lithosphere, which is part of the outer portion of the earth (the part we live on), the asthenosphere is just below it and the point where rocks begin to melt.

In which region of the Earth's interior does the heat increase to the point that rocks can begin to melt?
The heat increases to the point that rocks can begin to melt in the region known as the mantle. This layer lies beneath the Earth's crust and is composed of solid rock, but under high temperatures and pressure, some rocks can melt and form magma.
The energy source that drives the formation of igneous and metamorphic rocks is primarily heat generated by Earth's internal processes, such as volcanic activity or tectonic movements. This heat can come from the Earth's mantle or from the radioactive decay of elements within the crust. It causes rocks to melt and recrystallize, forming new rocks through processes like solidification or metamorphism.

The heat increases to the point that rocks can begin to melt in the lower part of the Earth's mantle, known as the asthenosphere. This is where the temperature and pressure conditions allow for rocks to melt and form magma.
In which region of the Earth's interior does the heat increase to the point that rocks can begin to melt?
In which region of the Earth's interior does the heat increase to the point that rocks can begin to melt?
At depths of 50 to 200 km below Earth's surface rocks will melt.
