Question

Considering how magma composition and temperature change as it rises toward the surface, categorize each of the magmas described below in terms of their position within the lithosphere and uppermost asthenosphere.

Answer 1

Upper Lithosphere / crust:

The Magma density was equal to or less than the crust

The Magma underwent a degassing during an eruption.

Lower Lithosphere:

The Magma density was less than in the lower lithosphere but higher at crust.

Magma undergoing partial crystallization of high-density minerals

Asthenosphere:

The Magma with the high temperature.

Step-by-step explanation:

• Base on the magma composition on the earth the changes in the temperature of the as the magma rises with the orientation of the crust as the upper lithosphere and the lower lithosphere and asthenosphere are given above.
