Match the descriptions with the terms.

The combination of abrasion and plucking.

Glaciers melt and leave behind rocks and sand.

A glacier picks up a rock.

Lines on a rock, made by glaciers that scraped the glacier bed.

A glacier moves down the mountain and drags rocks along.

Rocks at the base of the glacier scrape the glacier bed.

Water gets into little cracks in the rock. As the water freezes, it expands. The crack becomes bigger.

Rocks that are left behind when the glacier melts.

Rocks inside, underneath, besides and on top of glaciers

Deposition

Freeze-thaw weathering

Erosion

Plucking

Glacial till

Abrasion

Transportation

Striations

Moraines

Weathered material on transport by

• water
• ice
• wind

Weathered material on transport by water, wind and ice we call erosion.

It is like sandpaper, shaping the landscape.

transported by ICE

transported by WIND

transported by WATER

Make the correct combinations:

Erosion

Transportation

Deposition

The glacier makes a U-shaped valley

The glacier brought rocks from Scandinavia to The Netherlands

The glacier picks up rocks

The glacier melts and leaves rocks behind

Rocks in the glacier scrapes away rocks below the glacier

The glacier moves and there are rocks inside the glacier

Which process happens when..

Ice on the mountain flows into a river.

1. Evaporation
2. Condensation
3. Melting
4. Freezing
