They would melt.
Rocks that form when hot magma solidifies are igneous rocks.
by hot magma
Magma is molten rock. Rocks have very high melting temperatures.
Hot, fluid material. (magma)
Magma.
There are hot gases mixed with magma. Sometimes the pressure of the magma and hot gases increased a great deal when this happens the rocks deep inside the earth have melted on molten rocks which is called magma. This is how a magma occurs.
its forms by contact with hot magma
Felsic rocks have a lower melting point than mafic rocks and felsic magma has a lower temperature. In other words, felsic magma is not hot enough to melt mafic rock while mafic magma is hot enough to melt felsic rock.
asthenosphere
A "geothermal" spring is a "hot" spring where the water is hot at the surface, heated by hot rocks or magma at depth.
Beneath the crust (Surface) of the earth is the mantle. This is made of hot molten rocks known as magma.Hope you found this useful!
Igneous rocks are formed underground from a very hot substance called magma. As magma cools and hardens under extreme pressure, it forms igneous rocks.
