How Glaciers Change the World!

The video explains glaciers, their formation, and their role in Earth's history. Glaciers are large ice masses that store most of Earth's fresh water. They form from compressed snow over centuries and are found globally. Glaciers move slowly but can retreat due to warming, impacting sea levels and ecosystems. They provide insights into Earth's past climate and are crucial for water resources. However, recent warming has led to increased glacier retreat, posing environmental challenges.

What is the primary composition of glaciers?

• Layers of compressed snow

• Sand and gravel

• Solid rock

• Liquid water

Which continent is home to the world's largest glacier?

• Asia

• Europe

• North America

• Antarctica

During the Ice Age, what fraction of Earth's land was covered by ice?

• 1/3

• 1/2

• 2/3

• 1/4

What happens when glaciers retreat?

• They become stationary

• They melt more in summer than they build up in winter

• They move forward

• They grow larger

How can melting glaciers be beneficial?

• They increase sea levels

• They provide water for rivers

• They create deserts

• They cause droughts
