Glaciers and Landscape

What are glaciers?

• Frozen rivers of ice

• Huge chunks of mountains

• Powerful natural tools

• Nature's bulldozer

How do glaciers shape the land?

• By freezing cracks in the rock

• By melting rocks and stones

• By eroding material

• By transporting material

What is the process of erosion by glaciers called?

• Plucking

• Abrasion

• Deposition

• Freeze-thaw weathering

What happens to the eroded material as the glacier flows downhill?

• It is hidden inside the glacier

• It is transported on the top of the glacier

• It is left behind as the glacier melts

• It turns into melt water

What is the material left behind by a melting glacier called?

• Glacial till

• Melt water

• Rocks and stones

• Sand and clay

Where do glaciers exist today?

• In the coldest parts of our planet

• In the UK

• In rivers and lakes

• In the mountains

What has happened to many glaciers due to global warming?

• They have melted

• They have become more powerful

• They have moved to colder regions

• They have grown in size

The photograph shows a valley. Which agent of erosion most likely produced this valley's shape?

• blowing wind

• ocean waves

• moving ice

• running water

Which one is the first statement on how a glacier forms...

• During the summer months, some parts of the glacier begin to melt. This is called the Zone of Ablation

• The bottom layers become ice under all the weight and pressure.

• Where the snow does not melt from year to year, this is where a glacier begins to form. As the snow builds up, it compresses the bottom layers.

• Snow falls heavily near the top of the glacier during the colder winter months. This is called the Zone of Accumulation

What is an ice age?

• An Ice Age is a period of time of high temperatures, with glaciers expanding from the poles of the planet that can last for millions of years.

• An Ice Age is a period of time of low temperatures, with ski resorts expanding from the poles of the planet that can last for millions of years.

• An Ice Age is a period of time of low temperatures, with glaciers and ice sheets expanding from the poles of the planet that can last for millions of years.

• An Ice Age is a period of time of low temperatures, with glaciers and ice sheets expanding from the poles of the planet that can last for a few years.
