which statement explains what happens as magma rises inside a volcano?\ngases will contract in the chamber.\nthe pressure of the gas will disappear.\nthe magmatic pressure decreases.\nmagma moves to other chambers.

Answer

Brief Explanations:

As magma rises inside a volcano, the overlying rock - pressure decreases, so the magmatic pressure also decreases. Gases expand rather than contract as magma rises (due to decreased pressure), the pressure of the gas doesn't disappear, and there's no indication from the general process of magma rising that it moves to other chambers specifically because of rising.

Answer:

The magmatic pressure decreases.
