West Antarctic ice sheet collapse likely inevitable

The video discusses seismic activity beneath Antarctica's ice sheet, leading to the discovery of an active volcano that accelerates ice mass loss in West Antarctica. Although eruptions are unlikely to penetrate the ice surface, volcanic activity can melt the ice sheet, increasing water flow into the Ross Ice Shelf. Additionally, warmer ocean water forms caverns beneath the ice, eroding ice grounded on the ocean floor.

What was discovered beneath Antarctica's ice sheet due to seismic activity?

• A new species of fish

• An active volcano

• A hidden lake

• A large cavern

How does volcanic activity beneath the ice sheet affect the ice mass?

• It has no effect on the ice

• It creates new ice formations

• It melts the ice, increasing water flow

• It causes the ice to freeze more quickly

What is the consequence of volcanic activity on the Ross Ice Shelf?

• It slows down the ice flow

• It speeds up the ice flow

• It causes the ice to thicken

• It has no impact on the ice flow

What does warmer ocean water do to the ice grounded on the ocean floor?

• It forms caverns beneath the ice

• It strengthens the ice

• It causes the ice to rise

• It has no effect on the ice

What is the effect of caverns formed by warmer ocean water?

• They stabilize the ice

• They erode the ice

• They create new ice layers

• They have no effect on the ice
