Volcanes

Volcanoes provide insight into Earth's interior. They originate below the surface, where intense heat melts rock into magma. This magma can rise and erupt as lava, which flows like a river and solidifies into rock. Observing a volcano reveals rock that once erupted from deep within the planet.

What role do volcanoes play in our understanding of the Earth?

• They provide insights into the Earth's interior.

• They help in predicting weather patterns.

• They help us understand the Earth's atmosphere.

• They are important for understanding ocean currents.

Where do volcanoes originate from?

• From the Earth's atmosphere

• From the ocean floor

• From deep below the Earth's surface

• From the Earth's crust

What is magma?

• Solid rock found on the Earth's surface

• A type of volcanic ash

• Molten rock beneath the Earth's surface

• A type of volcanic gas

What is the difference between magma and lava?

• There is no difference; they are the same.

• Magma is molten rock beneath the surface, while lava is on the surface.

• Lava is molten rock beneath the surface, while magma is on the surface.

• Magma is found on the surface, while lava is underground.

What happens to lava once it cools?

• It turns into water.

• It becomes a type of gas.

• It hardens into solid rock.

• It evaporates into the atmosphere.
