Glaciers in Scotland

What is a glacier?

• A large body of water

• A large moving mass of ice

• A type of mountain

• A river that is frozen

How did glaciers form in Scotland?

• River water froze and turned into ice.

• Over a short time the climate cooled and after one big snow storm glaciers filled the valleys

• Frost built up over many years creating a river of ice.

• Over many years the climate cooled, snow fell and layered up. The air was squeezed out and compacted into a thick ice sheet.

When approximately did Scotland last have glaciers?

• About 10,000 to 12,000 years ago

• 500 years ago

• 2,000 years ago

• 100,000 years ago

Glaciers move......

• Same speed as water in a river

• Slowly, usually only a few hundred metres per year

• Very very slowly, only a few centimetres per year

When they move glaciers are able to wear away some of the rock underneath. In geography we call this....

• deposition

• erosion

• transportation

• wearing away rock
