Understanding Volcanic Liquids
When discussing the liquids that come from a volcano, it's essential to differentiate between magma and lava.
Magma vs. Lava
- Magma:
- This is the molten rock found beneath the Earth's surface.
- It is formed from the melting of rocks in the mantle and crust due to high temperatures and pressures.
- Magma can contain gases and other materials, making it less fluid compared to lava.
- Lava:
- Once magma erupts from a volcano and reaches the Earth's surface, it is called lava.
- Lava flows out during a volcanic eruption and cools down to form solid rock.
- Lava can vary in temperature and composition, leading to different types of eruptions and rock formations.
Why Option 'C' is Correct
- The question specifically asks for the liquid that emerges from a volcano during an eruption.
- The correct answer is c) Lava, as this term refers to the molten rock that flows out after volcanic activity.

Common Misunderstandings
- Some might confuse magma and lava due to their similarities.
- Remember: magma is underground; lava is above ground.
Conclusion
Understanding the difference between magma and lava is crucial in geology. Always remember that when a volcano erupts, the liquid that flows is referred to as lava, making option 'C' the correct answer in this case.
