Which statement accurately describes lava and magma according to the material?

• A. Lava is molten rock above ground; Magma is molten rock below ground
• B. Lava is molten rock below ground; Magma is molten rock above ground
• C. Both are solid rocks
• D. Lava and magma refer to gases

Answer: (A)

The main idea is the location where the molten rock exists. Molten rock beneath the Earth’s surface is called magma, while once that molten material erupts onto the surface or flows out of a volcano, it becomes lava. This distinguishes the two terms by where the rock is: magma underground, lava above ground. The statement matches that distinction by saying lava is molten rock above ground and magma is molten rock below ground. The other ideas aren’t accurate because molten rock isn’t considered solid, and these terms aren’t used for gases.
