Question

The layer of the earth which supplies magma during the volcanic eruption is called ______.

Options

• Mesosphere

• Asthenosphere

• Barysphere

• Lithosphere

Answer 1

The layer of the earth which supplies magma during the volcanic eruption is called asthenosphere.

Explanation:

The asthenosphere is the upper part of the mantle and is in a molten or semi-molten state. It supplies the magma that causes volcanic eruptions when it rises through the earth’s crust. Other layers like the mesosphere and lithosphere do not supply magma directly. The barysphere refers to the core and is unrelated to magma supply during eruptions.
