How scientists are tracking a massive iceberg in the making

The video discusses the rapid changes in the Larsen C ice shelf in Antarctica, highlighting its potential to form a massive iceberg. It explains the impact of ice shelf collapse on sea levels and glacier flow, using analogies like fingernails and ice cubes. Historical events of ice shelf disintegration, such as Larsen A and B, are covered, emphasizing the unexpected scale of these changes. The role of satellite technology in monitoring these changes is explored, with a focus on past and future NASA missions. The video concludes with the ongoing threat of climate change to Antarctic ice.

What is the potential size of the iceberg forming from the Larsen C ice shelf?

• The size of Texas

• The size of Delaware

• The size of California

• The size of New York

How do rising air and sea temperatures affect the Antarctic ice?

• They slow down the ice flow

• They have no effect on the ice

• They accelerate the rift propagation

• They cause the ice to become static

What analogy is used to describe the flow of glacier ice?

• Syrup on a pancake

• Smoke in the air

• Water in a river

• Sand in an hourglass

What is the indirect effect of ice shelf collapse on sea levels?

• It causes sea levels to drop

• It allows upstream glaciers to flow faster

• It has no effect on sea levels

• It directly raises sea levels

What natural process involves ice breaking off from glaciers?

• Melting

• Freezing

• Calving

• Condensation

What analogy is used to explain the impact of losing large ice sections?

• A broken window

• A cracked mirror

• A broken fingernail

• A torn page

Which satellite provided crucial data on ice changes before ceasing operation in 2009?

• Icesat

• Landsat

• Voyager

• Hubble
