Aftermath of the Biggest Volcano Eruption Ever

The video discusses a significant volcanic eruption that occurred on January 14th, capturing the largest explosion ever recorded on camera. The eruption produced a massive ash cloud, volcanic lightning, and a shockwave that traveled globally. Nearby islands were covered in ash, affecting the environment and water supplies. The ash reached the stratosphere, potentially causing global cooling and acid rain. The eruption also caused a small tsunami. The volcanic island, formed in 2014, was studied for its erosion patterns, providing insights into similar processes on Mars. The eruption's force decimated the island, splitting it into two separate landmasses.

What was the height of the ash cloud produced by the eruption on January 14th?

• 10 kilometers

• 20 kilometers

• 40 kilometers

• 30 kilometers

What is one of the suspected causes of volcanic lightning?

• Positively charged particles from the eruption

• Solar radiation

• Negatively charged particles from the ocean

• Magnetic fields from the Earth's core

How does volcanic ash in the stratosphere affect Earth's climate?

• It causes global warming

• It has no effect

• It may cause slight cooling

• It increases rainfall

What is a potential consequence of ash particles returning to the troposphere?

• Increased snowfall

• Acid rain

• Higher temperatures

• Drought

How many times did the pressure wave from the eruption travel around the world?

• At least four times

• Three times

• Once

• Twice

What was the primary reason the eruption caused a tsunami?

• The eruption was underwater

• The eruption was on land

• The eruption was near a fault line

• The scale and suddenness of the explosion

Why is the volcanic island of interest to NASA?

• It is a tourist attraction

• It is a potential site for a space base

• It helps understand water's impact on volcanoes

• It is rich in rare minerals
