Melting ice has warped Earth’s crust

The video discusses a study on the deformation of the Earth's crust due to ice melting, highlighting the 3D nature of this deformation, which includes both vertical and horizontal movements. The study reveals that ice loss impacts not only local areas but also has global effects, particularly in the northern hemisphere. A case study of London shows measurable crust movement. An analogy is used to explain the concept of crust movement.

What is the process called when the Earth's crust rises due to glacier melting?

• Seismic shift

• Volcanic eruption

• Isostatic rebound

• Tectonic uplift

According to the new study, how does crust deformation occur?

• Only horizontally

• Only vertically

• Not at all

• In three dimensions

Which region is mentioned as being affected by crust deformation due to ice melting?

• Sydney

• London

• Tokyo

• New York

What analogy is used to explain crust deformation?

• A spinning top

• A wooden board on water

• A balloon expanding

• A rubber band stretching

What happens to the water when the wooden board is lifted in the analogy?

• It evaporates

• It moves vertically to fill the space

• It moves horizontally

• It stays still
