Which of the following terms is used for the molten material, mixed with gases, in the mantle of the earth?
ALitho
BLava
CGeyser
DMagma ✓ Correct
Correct answer: (D) Magma
Explanation
Magma is the molten rock mixed with dissolved gases held below the surface within the earth's mantle and crust.
Litho is only a prefix meaning stone, not a name for molten material.
Lava is the same molten material after it erupts and flows out onto the surface.
A geyser is a jet of hot groundwater and steam, not molten rock.
High temperature and pressure at depth keep magma partly liquid until it rises through weak zones.
When magma cools underground it forms intrusive igneous rocks like granite.
