Glacier Landforms Quiz

The three main types of glaciers described in the text are continental glaciers, alpine glaciers, and tidewater glaciers.

Hanging valleys are formed when a glacier carves out a deep valley and then melts, leaving the valley suspended in the mountain range. They usually end with a waterfall.

Some landforms created by glaciers include moraines, drumlins, and kettle lakes.

<p>The two main types of glaciers are continental glaciers and alpine glaciers. Continental glaciers are found in Antarctica and Greenland, while alpine glaciers are found high in the mountains.</p> Signup and view all the answers

<p>Striations are scratches on the ground in the direction of the glacier's flow. They are formed as the glacier slowly slides across the earth, picking up rocks and other debris underneath it.</p> Signup and view all the answers

<p>The two main types of glaciers are continental glaciers and alpine glaciers. Continental glaciers are large, flat areas of ice that cover extensive portions of land. Alpine glaciers, on the other hand, are found in mountainous regions and valleys.</p> Signup and view all the answers

<p>Glaciers form from compacted snow. As snow falls and accumulates, the pressure builds up and compresses the snow, turning it into ice.</p> Signup and view all the answers

<p>Glaciers can move in two ways: internal flow and basal sliding. Internal flow occurs due to the weight and shape of the ice, causing some parts to melt or shift, allowing the glacier to move. Basal sliding, on the other hand, is the movement of the entire glacier over its base, usually due to the presence of a lubricating layer of water.</p> Signup and view all the answers

<p>Moraines are boulders and sediment deposited by the glacier as it melts, creating ridges or piles. They are formed when the glacier leaves debris behind as it melts.</p> Signup and view all the answers

<p>Drumlins are elongated hills that have been streamlined by the glacier. They are formed when the glacier shapes the land into hills with a half-buried egg or whale's back appearance.</p> Signup and view all the answers

<p>Kettle lakes are formed as glaciers carve out the land, melt, and leave a lake behind. They are formed when the glacier creates depressions in the land that fill with water as the glacier melts.</p> Signup and view all the answers

<p>The three types of glaciers mentioned in the text are continental glaciers, alpine glaciers, and tidewater glaciers. Continental glaciers are found at the earth's poles and in very cold places like Greenland. Alpine glaciers are found on top of mountains and in the valleys between them. Tidewater glaciers are alpine glaciers that meet the ocean.</p> Signup and view all the answers

<p>Moraines are small, perpendicular mountains that occur along the edge of where a glacier stopped moving forward. Drumlins are elongated hills that look like a whale's back.</p> Signup and view all the answers

<p>Glaciers are important for fresh water sources because they act as a frozen reservoir for most of the Earth's fresh water. They feed rivers and oceans with water. Glaciers are greatly affected by climate change. As the Earth becomes warmer, glaciers melt and become more mobile. The effects of this accelerated melting are not fully understood.</p> Signup and view all the answers
