Question

What is the sorce of high temperature of magma?

"Anyone don't give the definition of magma or temperature of magma otherwise I will report okay...."


​

Answer 1

Answer:

Lava is hot for two primary reasons: Pressure and radiogenic heating make it very hot deep in the Earth (about 100 km down) where rocks melt to make magma . The rock around the magma is a good insulator so the magma doesn't lose much heat on the way to the surface.

Answer 2

Answer:

Temperatures of most magmas are in the range 700 °C to 1300 °C (or 1300 °F to 2400 °F), but very rare carbonatite magmas may be as cool as 490 °C, and komatiite magmas may have been as hot as 1600 °C. At any given pressure and for any given composition of rock, a rise in temperature past the solidus will cause melting.
