Exploring Glacial Impact on Landscapes

Glaciers, powerful frozen rivers of ice, shape landscapes through erosion, transportation, and deposition. They erode by freeze-thaw weathering, plucking, and abrasion, transporting materials downhill. As glaciers melt, they deposit rocks and sediments, forming glacial till. Historically, glaciers shaped regions like the UK, leaving behind unique landscapes. With climate change, glaciers are rapidly melting, urging us to witness their impact while we can.

Why do glaciers often look dirty?

• Due to wildlife

• From volcanic ash

• Because of pollution

• From the material they transport

What happens to the material carried by a glacier when it melts?

• It falls to the ground

• It gets absorbed by the glacier

• It evaporates

• It is transported further by wind

What is glacial till?

• Water from melted ice

• A type of mountain

• The top layer of a glacier

• A mixture of rocks, stones, sand, and clay

During which period did glaciers exist in the UK?

• Jurassic period

• Last ice age

• Cretaceous period

• Holocene epoch

What is the fate of glaciers as our planet warms up?

• They are melting fast

• They turn into rivers

• They move to colder areas

• They grow larger
