Glacier Movement and Flubber Experiment

The video tutorial explains glaciers, focusing on their formation, movement, and impact on the environment. It highlights the Greenland Ice Sheet's significance, detailing how snow accumulates and transforms into ice. A lab experiment using Flubber demonstrates glacier movement, emphasizing glaciers' role in shaping landscapes and responding to climate changes.

What percentage of the world's land mass is covered by glaciers?

• 5%

• 30%

• 10%

• 20%

How much of the world's fresh water is stored in glaciers?

• 80%

• 70%

• 60%

• 50%

What is the thickness of the Greenland Ice Sheet at its center?

• 4,000 meters

• 3,200 meters

• 2,400 meters

• 1,600 meters

Why does the snow in the center of Greenland not melt during summer?

• The sun never shines there.

• The snow reflects the sun's heat.

• The snow is too thick.

• It is too cold to melt.

What is the dense layer formed from compacted snow called?

• Slush

• Glacial till

• Firn

• Permafrost

What material is used in the lab experiment to simulate glacier movement?

• Gelatin

• Flubber

• Sand

• Clay

What are the basic ingredients of Flubber used in the experiment?

• Clay, Water, Sand, Dye

• Glue, Water, Salt, Food coloring

• Glue, Borax, Water, Food coloring

• Gelatin, Water, Salt, Dye

What is the purpose of coating the inside of the pipes with different materials in the experiment?

• To make the Flubber flow faster

• To simulate different terrains

• To change the color of the Flubber

• To prevent the Flubber from sticking

Why is understanding glacier flow important for scientists?

• To predict weather patterns

• To study animal habitats

• To understand sea level rise

• To find new water sources

What role do glaciers play in shaping the landscape?

• They create new mountains.

• They erode and carve valleys.

• They build up sand dunes.

• They form new rivers.
