Icebergs and Glaciers Concepts

The video explains glaciers as large, slow-moving ice masses formed from compacted snow, typically found on cold, high mountains. Glaciers move gradually, dragging rocks and dirt, causing erosion and altering landscapes. As glaciers descend into warmer areas, they melt, contributing water to rivers and lakes. Some glaciers reach the ocean, where parts break off to form icebergs, which vary in size and mostly remain submerged.

What is a glacier primarily made of?

• Freshwater ice

• Frozen soil

• Saltwater ice

• Sand and rocks

Where are glaciers typically found?

• In tropical forests

• In deserts

• In urban areas

• On high mountains

What process occurs when glaciers move and alter the landscape?

• Deposition

• Compaction

• Erosion

• Sedimentation

What happens to a glacier when it moves into a warmer area?

• It grows larger

• It stops moving

• It melts

• It freezes more

What are the floating chunks of ice called when they break off from a glacier?

• Ice floes

• Ice sheets

• Icebergs

• Glacierettes

How large can icebergs be?
