New lava tubes sending La Palma lava flowing downhill at high speeds

The video discusses the ongoing volcanic eruption, with lava flowing towards the Atlantic Ocean at speeds of up to 1 meter per second. It explains the formation of lava tubes, which occur when the surface of a lava flow cools faster than the underlying lava, creating an insulating crust. This allows the lava to remain hot and travel further. Different volcanic activities at various vents are influencing the lava flow. In response to the damage caused, a neighboring island's president suggested bombing the volcano to alter the lava's path.

What is the speed at which molten lava is moving towards the Atlantic Ocean?

• 10 meters per second

• 5 meters per second

• 1 meter per second

• 20 meters per second

Which institution is cited for explaining the formation of new lava tubes?

• Stanford University's Earth Sciences Department

• MIT's Department of Geology

• Oxford University's Volcanology Institute

• Harvard University's Department of Earth and Planetary Sciences

What causes the formation of a crust on the top surface of a lava flow?

• Increase in lava temperature

• Rapid cooling of the top surface

• Interaction with ocean water

• Decrease in lava viscosity

What is the effect of the insulating crust on the underlying lava?

• It changes the lava's chemical composition

• It stops the lava flow completely

• It causes the lava to cool down quickly

• It allows the lava to stay hotter and flow further

What unusual method was suggested to change the direction of the lava flow?

• Constructing a diversion channel

• Using water cannons

• Building a large dam

• Bombing the volcano
