Does the magma inside earth heat the rock to a very high temperature?

Yes, magma inside the Earth reaches very high temperatures, typically ranging from 700 to 1,300 degrees Celsius (1,300 to 2,400 degrees Fahrenheit). This intense heat is due to the pressure and geothermal gradient found within the Earth's mantle and crust. The high temperatures can cause surrounding rocks to partially melt, contributing to volcanic activity and the formation of igneous rocks.
