NASA | Tohoku Tsunami Creates Antarctic Icebergs

The video discusses the discovery of an ice mass separation in Antarctica, triggered by the Tohoku earthquake and tsunami. Satellite imagery from NASA and the European Space Agency revealed the separation of large icebergs from the Salzburger Ice Shelf. Historical data shows the ice shelf had been stable for over 46 years, suggesting sea ice plays a critical role in its stability.

What was the initial belief about the possibility of ice mass separation before Asuni's discovery?

• It was considered impossible by the scientific community.

• It was widely accepted as a common occurrence.

• Scientists had concrete evidence of its possibility.

• It was only a speculative idea among scientists.

Which natural event contributed to the sea swell that affected the Salzburger Ice Shelf?

• An earthquake in California

• A hurricane in the Atlantic Ocean

• The Tohoku earthquake and tsunami

• A volcanic eruption in Hawaii

How far did the sea swell travel to reach the ice shelf?

• 10000 miles

• 8000 miles

• 2000 miles

• 500 miles

What technology was used to observe the separated ice mass?

• Weather balloons

• Underwater drones

• Satellite imagery

• Seismic sensors

What historical evidence suggested the stability of the ice shelf before the separation?

• Aerial photos from 1965

• Ice core samples

• Old satellite images

• Ancient maps
