Volcanoes and Earthquakes Unveiling Earth's Hidden Forces

The video explains the nature of volcanoes and earthquakes, highlighting the forces within the Earth. It describes how volcanoes erupt due to magma pressure and how earthquakes result from tectonic plate movements. The video emphasizes the destructive power of these natural phenomena and provides insight into the Earth's interior.

What happens to a volcano when it erupts?

• It cools down.

• It reveals the forces inside the Earth.

• It becomes a mountain.

• It disappears.

What is magma?

• Cold liquid rock.

• Solid rock from the Earth's crust.

• A type of volcanic ash.

• Hot liquid rock from the Earth's mantle.

How does magma reach the surface?

• Through rivers.

• Through chimneys connected to volcanoes.

• By evaporating.

• By cooling down.

What causes the Earth to shake during an earthquake?

• The eruption of a volcano.

• The movement of tectonic plates.

• The cooling of magma.

• The formation of mountains.

What is the epicenter of an earthquake?

• The point where the earthquake starts.

• The safest place during an earthquake.

• The place where magma is stored.

• The top of a volcano.

What happens when tectonic plates slide in opposite directions?

• They stop moving.

• They form new volcanoes.

• They create new mountains.

• They cause earthquakes.

What do volcanoes and earthquakes reveal about the Earth?

• The Earth's crust is unbreakable.

• The Earth's interior has enormous energy.

• The Earth's interior is calm and stable.

• The Earth's surface is very cold.

Why are volcanoes and earthquakes fascinating?

• They are harmless.

• They occur only in specific regions.

• They provide a dramatic look at the Earth's interior.

• They are easy to predict.
