Thinking About Glaciers
Thinking About Glaciers
Glaciers cover about one-tenth of the Earth’s surface.
Most of the fresh water found on the Earth is frozen in
glaciers.
Glaciers move very slowly and can cause very slow
changes to the Earth’s surface.
What are glaciers? How do glaciers form? How do
glaciers change our Earth?
Words to Know
Words to Know
•
Glacier—a large body of moving ice that stays frozen all
year
•
Iceberg—a large mounded mass of ice that has broken away
from a glacier and floats in the sea
•
Moraine—a ridge of rocks left by a glacier
•
U-shaped valley—low-lying area of land surrounded by
higher ground formed by the movements of a glacier
What are Glaciers?
What are Glaciers?
Glaciers are large areas of ice and snow that move very slowly.
Where are Glaciers?
Where are Glaciers?
Some glaciers are in mountains. Some glaciers hang on
mountains. Some glaciers are in cirques, areas in mountains
rubbed away by glaciers.
Hanging Glacier
Cirque Glacier

Where are Glaciers?
Some glaciers are
in mountain
valleys. These
glaciers look like
rivers of ice and
snow.
Valley Glaciers
Valley Glaciers
Valley glaciers move down mountains. As they move over the
Earth’s surface, rocks and dirt break off and are picked up by
the glacier. The rocks and dirt become part of the glacier.

Glaciers, vast bodies of moving ice, play a significant role in shaping the Earth's surface by slowly moving and accumulating rocks and dirt. They cover about one-tenth of the Earth's surface and hold a large portion of the planet's fresh water as ice. Glaciers are found in various forms such as cirques, hanging glaciers, and valley glaciers, each contributing to the reshaping of landscapes over time. Understanding the formation, movement, and effects of glaciers provides valuable insights into the dynamic changes occurring on our planet.
