The most appropriate answer would be magma. Lava is a magma that reaches the Earth's surface, which is technically it is also a magma, and magma is located below the Earth's surface.
Lava at Earth's surface or magma below Earth's surface cools and harden to form mineral crystals.
Answer:
The greater the amount of silica in magma, the more viscous the magma is. The magma thus solidifies quicker as well.
