Greenland Ice Sheet is sliding more than anyone realized, impacting sea level rise!

Researchers from the universities of Wyoming and Montana discovered that the Greenland ice sheet slides more than previously thought, even in winter when no meltwater is present. This movement impacts sea level rise. The team used 212 tilt sensors in boreholes to study changes in the ice sheet's shape and movement, aiming to improve ice sheet models for predicting future ice loss.

Which universities discovered the increased sliding of the Greenland ice sheet?

• Stanford and MIT

• Wyoming and Montana

• Oxford and Cambridge

• Harvard and Yale

What is unusual about the Greenland ice sheet's sliding behavior?

• It does not slide at all

• It slides over hard bedrock in winter

• It slides during summer only

• It slides over soft soil

What is the consequence of ice moving from high to low elevations?

• It creates new ice formations

• It has no significant impact

• It leads to sea level rise

• It causes earthquakes

How many tilt sensors were installed by the research team?

• 100

• 150

• 212

• 300

What is the main goal of installing tilt sensors in the ice sheet?

• To measure temperature changes

• To monitor air quality

• To observe changes in ice shape and movement

• To track wildlife migration
