Magma is molten rock material that forms igneous rocks when cooled when magma reaches the surface then it is lava.

Can someone please explain in more detail how to properly make magma?

Magma is formed by the melting of rocks. Magmas form in the crust and the mantle. To melt rock and form magma, very high temperatures are needed. Rock composition, pressure and water content all influence the melting point of rock. As plates are subduced and "swallowed" toward the earth's hot core, the rocks begin to melt, forming magma. The main difference between magam and lava are the places in which they are found. Magma is what is formed by the melting of rocks and the mixing of different chemicals in the rocks. Lava is what flows from cracks in the earth's crust. I hope this helps you.
