Rock are carried along inside an and drop off as it melts?
This describes glacial erosion where rocks are frozen into the base of a glacier and then deposited as the glacier melts, leaving behind a trail of rocks.
What is the general term for all sediments deposited by a glacier?
Glacial deposits, often referred to as glacial drift, are the general term for all sediments deposited by a glacier. This can include material like till, moraine, and glacial erratics left behind as the glacier moves and melts.
When a glacier melts the rocks it carried fall to the ground in a jumble called what?
When a glacier melts, the rocks it carried may fall to the ground in a jumble called a moraine. This accumulation of rock, debris, and soil can form a moraine deposit at the edge or base of a glacier.
What is the term for all sediments of glacier origin called?
The term for all sediments of glacier origin is "glacial till." It consists of a mixture of rock fragments of various sizes that are deposited directly by the ice as it moves and melts.
Eskers and Kettle lakes are the result of?
Eskers are winding ridges of sediment deposited by meltwater streams flowing under glaciers. Kettle lakes are formed when a block of ice from a retreating glacier gets buried in sediment and then melts. Both eskers and kettle lakes are common features of glacial landscapes.
What is the difference between glacier erosion and glacial deposition?
Glacier erosion is the process by which glaciers wear away rocks and soil as they move, sculpting the landscape through processes like plucking and abrasion. Glacial deposition is when glaciers deposit the material they have eroded elsewhere, forming features like moraines, drumlins, and eskers. In essence, erosion involves the removal of material, while deposition involves the accumulation of material.
What is the difference between glacier erosion and glacier deposition?
Glacier erosion is when the ground below the glacier is removed. Glacial deposition is when the debris (eroded ground) is left behind when a glacier melts and the face retreats.
When a glacier melts the rocks it carried fall to the ground in a jumble called what?
When a glacier melts, the rocks it carried may fall to the ground in a jumble called a moraine. This accumulation of rock, debris, and soil can form a moraine deposit at the edge or base of a glacier.
How is snow transformed into glacial ice?
Snow is transformed into glacial ice through a process called firnification, where successive layers of snow are compressed under their weight into firn, a compacted snow with some air pockets. Over time, the firn undergoes further compaction and recrystallization, becoming glacial ice. This process can take several decades to centuries depending on the accumulation rate and temperatures.
Eskers and Kettle lakes are the result of?
Eskers are winding ridges of sediment deposited by meltwater streams flowing under glaciers. Kettle lakes are formed when a block of ice from a retreating glacier gets buried in sediment and then melts. Both eskers and kettle lakes are common features of glacial landscapes.
Ridge consisting of unsorted sediments deposited at the sides of a glacier?
The ridge is called a lateral moraine, which forms when unsorted sediments are deposited along the sides of a glacier as it flows downhill. This accumulation of debris is typically carried by the glacier and then left behind as the glacier retreats or melts. Lateral moraines can provide valuable information about past glacial activity and the direction of glacier movement.
Are glaciers agents of erosion?
Yes. Look at any glacial (u-shaped) valley and the terminal moraine at the end where the glacier melts.

Yes. Look at any glacial (u-shaped) valley and the terminal moraine at the end where the glacier melts.
What is a glacial till?
Glacial till is a type of sediment deposited by glaciers through the process of erosion and transportation. It is a mixture of different sized particles, ranging from clay to boulders, that is left behind as the glacier melts. Glacial till is an unsorted and unstratified deposit.
What happens when a glacier melts?
What can happen when the glacier melts in a cirque
What happens where a glacier enters the sea?
When a glacier enters the sea, it creates a floating ice shelf. This ice shelf can calve off icebergs as it melts or breaks apart. The melting of glaciers into the sea also contributes to rising sea levels and changes in ocean circulation patterns.
What does a glacier deposit as it recedes?
As a glacier recedes, it deposits materials such as rocks, sand, and gravel that were previously frozen within the ice. These deposits are known as glacial moraines and can vary in size and composition depending on the glacier's movement and the type of material it picks up along its path.
