Question

where do you think magma comes from?

Explanation:

Magma is formed from the partial melting of the Earth's mantle. The mantle is a layer of hot, solid rock that lies beneath the Earth's crust. When the temperature and pressure conditions in the mantle are right, some of the rock melts to form magma. Magma can also be formed from the melting of the Earth's crust. This can happen when the crust is heated by magma from the mantle or by the impact of meteorites.

Answer:

Magma comes from the partial melting of the Earth's mantle or crust.
