Outwash plain
An outwash plain is a broad, flat plain of sand and gravel that is deposited by a glacier as it melts. The outwash plain is formed when meltwater from the glacier flows away from the ice front and spreads out over the land. The meltwater carries with it sand and gravel, which are deposited as the water slows down and spreads out. The outwash plain is typically much wider than the glacier itself, and it can extend for many miles from the ice front.
Esker
An esker is a long, winding ridge of sand and gravel that is deposited by a stream of meltwater that flows beneath a glacier. The esker is formed when the meltwater flows through a channel in the ice and carries with it sand and gravel. The sand and gravel are deposited as the water slows down and spreads out at the end of the channel. The esker is typically several miles long and a few hundred feet wide.
Kame terrace
A kame terrace is a small, terraced hill that is formed by a stream of meltwater that flows over a glacier. The kame terrace is formed when the meltwater flows over a ridge of ice and deposits sand and gravel. The sand and gravel are deposited as the water slows down and spreads out at the end of the ridge. The kame terrace is typically a few hundred feet long and a few dozen feet wide.
Drumlin
A drumlin is a long, low hill that is formed by a glacier. The drumlin is formed when the glacier pushes a mass of sand and gravel along the ground. The sand and gravel are deposited as the glacier moves forward. The drumlin is typically a few hundred feet long and a few dozen feet high.
Kettle hole
A kettle hole is a small, round depression that is formed when a block of ice melts in a glacier. The kettle hole is formed when the ice block melts and leaves a hole in the ground. The kettle hole is typically a few dozen feet wide and a few feet deep.
Moraine
A moraine is a ridge or mound of rock, debris, and SoilSoil that is deposited by a glacier. Moraines are formed when the glacier moves forward and pushes the rock, debris, and soil along the ground. The moraine is typically several miles long and a few hundred feet wide.
Outwash plains, eskers, kame terraces, drumlins, kettle holes, and moraines are all landforms that are formed by glaciers. These landforms are important because they provide evidence of the past presence of glaciers. They can also be used to study the movement of glaciers and the climate conditions that existed when the glaciers were present.
Outwash plain
- What is an outwash plain?
An outwash plain is a flat, fan-shaped deposit of sand and gravel that forms when meltwater from a glacier spreads out and flows away from the ice front. - How are outwash plains formed?
Outwash plains are formed when meltwater from a glacier spreads out and flows away from the ice front. The meltwater carries with it sand and gravel, which are deposited as the water slows down and spreads out. - Where are outwash plains found?
Outwash plains are found in front of glaciers, where meltwater flows away from the ice front. They are also found in areas where glaciers have retreated in the past. - What are the features of an outwash plain?
Outwash plains are typically flat, with a gently sloping surface. They are made up of sand and gravel, which can be sorted by size. Outwash plains may also contain kettle holes, which are depressions that form when blocks of ice melt and leave behind a hole in the ground.
Esker
- What is an esker?
An esker is a long, winding ridge of sand and gravel that forms when meltwater from a glacier flows through a narrow channel. - How are eskers formed?
Esker are formed when meltwater from a glacier flows through a narrow channel. The meltwater carries with it sand and gravel, which are deposited as the water slows down and spreads out. The sand and gravel are deposited in layers, which form the ridge of an esker. - Where are eskers found?
Esker are found in front of glaciers, where meltwater flows through narrow channels. They are also found in areas where glaciers have retreated in the past. - What are the features of an esker?
Esker are typically long, winding ridges that are several meters high. They are made up of sand and gravel, which can be sorted by size. Eskers may also contain kettle holes, which are depressions that form when blocks of ice melt and leave behind a hole in the ground.
Kame terrace
- What is a kame terrace?
A kame terrace is a small, terrace-like hill that forms when meltwater from a glacier deposits sediment on a sloping surface. - How are kame terraces formed?
Kame terraces are formed when meltwater from a glacier deposits sediment on a sloping surface. The meltwater carries with it sand and gravel, which are deposited as the water slows down and spreads out. The sand and gravel are deposited in layers, which form the terrace-like hill of a kame terrace. - Where are kame terraces found?
Kame terraces are found in front of glaciers, where meltwater flows over sloping surfaces. They are also found in areas where glaciers have retreated in the past. - What are the features of a kame terrace?
Kame terraces are typically small, terrace-like hills that are several meters high. They are made up of sand and gravel, which can be sorted by size. Kame terraces may also contain kettle holes, which are depressions that form when blocks of ice melt and leave behind a hole in the ground.
Drumlin
- What is a drumlin?
A drumlin is a long, low hill that forms when a glacier pushes and rolls over sediment. - How are drumlins formed?
Drumlins are formed when a glacier pushes and rolls over sediment. The sediment is deposited in layers, which form the long, low hill of a drumlin. - Where are drumlins found?
Drumlins are found in front of glaciers, where the glacier pushes and rolls over sediment. They are also found in areas where glaciers have retreated in the past. - What are the features of a drumlin?
Drumlins are typically long, low hills that are several meters high. They are made up of sand and gravel, which can be sorted by size. Drumlins are typically oriented in the direction of the glacier’s movement.
Kettle hole
- What is a kettle hole?
A kettle hole is a depression that forms when a block of ice melts and leaves behind a hole in the ground. - How are kettle holes formed?
Kettle holes are formed when a block of ice melts and leaves behind a hole in the ground. The ice block is typically buried in sediment, and when it melts, the sediment collapses and forms a depression. - Where are kettle holes found?
Kettle holes are found in areas where glaciers have retreated in the past. They are also found in areas where the ground has been disturbed, such as by construction or mining. - What are the features of a kettle hole?
Kettle holes are typically circular or oval depressions that are several meters deep. They may be filled with water, forming a lake or pond. A long, winding ridge of sand and gravel deposited by a stream of meltwater from a glacier is called a:
