* Magma is molten rock found beneath the Earth's surface.

* Lava is magma that has erupted onto the Earth's surface.

So, lava is the result of magma, not a component of it.

The other options are components of magma:

* Partially melted mineral crystals: Magma is formed by the partial melting of rocks, resulting in a mixture of solid and liquid components.

* Water: Water is a common component of magma, playing a significant role in its fluidity and eruption dynamics.

* Dissolved gases: Gases like carbon dioxide, sulfur dioxide, and water vapor are dissolved in magma under pressure. When magma rises, the pressure decreases, allowing these gases to expand and contribute to volcanic eruptions.
