when meltwater at a glacier's base refreezes to bedrock, loosened rocks will be torn away as the glacier moves forwards, here rocks freeze to a glacier and are pulled from the ground as it moves

where rocks carried beneath the ice scratch and sandpaper the bedrock

a ridge or mound of debris deposited by a glacier

Glacial processes

Geography

This unit teaches pupils about the physical processes that influence cold places around the world and how areas of ice have changed over time due to climatic variations. Pupils will learn about the impact of global warming on glaciated areas and what this means for the future of our planet.

Ice and glaciers: How are cold places affected by a warming planet?

Glaciers are white because they are made of ice.

Glaciers can appear dirty because they carry material.

What is the process called when a glacier moves and shapes the land beneath it?

When the glacier pulls rocks and debris out of the ground

When the glacier deposits rocks at the end

Which of the following describes glacial erosion by plucking?

When the glacier melts and forms water channels

When a glacier moves forward due to gravity

When the glacier grinds and scrapes the ground with debris

Which of the following describes glacial erosion by abrasion?

What are the two main types of cold environments?

Which of these is a type of ice formation found in cold climates?

It reflects sunlight, preventing too much heat from entering Earth

How does ice help keep Earth's temperature stable?

A large block of rock found in the desert

A large mass of freshwater ice floating in the ocean

Which of these countries is known for having a cold environment with glaciers and ice?
