Magma is not all that abundant. The mantle itself is solid due to the pressure it is under. When magma comes in contact with solid rock, some of that rock may melt, but it takes a lot of heat to melt rock. Once it reaches the melting point, more energy is needed to actually melt it. Additionally, rock does not transfer heat easily. The sheer volume of the rock also keeps the entirety of it melting. It is like pouring a bucket of water on a glacier.

a type of rock that forms when magma cools and hardens very slowly deep in earths crust...
Are The elements found in magma are quite different from those found in Earths crust?
Yes, the elements found in magma can be different from those found in Earth's crust. Magma can contain a higher concentration of elements like silicon, aluminum, magnesium, iron, and calcium compared to the crust, as these elements are more common in the mantle where magma is primarily formed. Additionally, the process of partial melting and differentiation can lead to variations in element composition between magma and the crust.

What are some properties of magma?
Magma has a lot of different properties. it also means lava. It is in the mantlle if it is called magma, lava is when it is on the earths crust.
Does a volcano form when magma reaches earths surface?
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
How does magma rise to the surface of the Earth?
Through cracks, holes or vents in the earths crust.
