CLEAN : Iceland lowers aviation alert on volcano

The video explores the dynamics of molten magma, highlighting its power and propagation around a volcano. It discusses how magma extends into the Earth's crust, currently reaching 40 kilometers from the volcano. The video raises questions about the potential impact if the magma reaches the active Alaska volcano, pondering whether it could trigger an eruption or stop before reaching the old cable.

What is the initial effect of magma as it forms around a volcano?

• It forms a dike.

• It causes an earthquake.

• It cools down rapidly.

• It creates a crater.

As the dike receives more material, what happens to its length?

• It disappears.

• It gets longer.

• It remains the same.

• It becomes shorter.

How far has the dike propagated from the volcano?

• 50 kilometers

• 30 kilometers

• 40 kilometers

• 20 kilometers

What is the main concern if the dike reaches the active volcano in Alaska?

• It might cause a landslide.

• It could trigger an eruption.

• It will stop the volcano's activity.

• It will create a new volcano.

What is uncertain about the dike's journey towards the old cable?

• Whether it will change direction.

• If it will stop before reaching it.

• If it will become a river.

• Whether it will increase in temperature.
