A mixture of sediment that a glacier deposits on the surface is called "glacial till." This material is composed of various sizes of sediment, including clay, silt, sand, gravel, and boulders, which have been eroded and transported by the moving ice. When the glacier melts, it drops this unsorted debris, forming landforms such as moraines, drumlins, and outwash plains. Glacial till is significant for understanding past glacial movement and the geological history of an area.

What is the mixture of sediment a glacier deposits on the surface?
A glacier deposits a mixture of rocks, sand, silt, and clay called glacial till. This sediment is unsorted and unstratified, with a wide range of particle sizes from boulders to clay particles. Glacial till is deposited as the glacier retreats and melts, creating landforms like moraines and drumlins.
What is and rocks left behind in a glacier?
Rocks left behind in a glacier are known as glacial till, which consists of a mixture of various sizes of sediment, including clay, silt, sand, gravel, and boulders. As glaciers move, they erode the landscape, picking up and transporting these materials. When the glacier melts, it deposits the till, creating features such as moraines, drumlins, and outwash plains. This process plays a significant role in shaping the Earth's surface and contributing to soil formation.
How is wind erosion different from water and glacier erosion?
Wind erosion is the process by which wind moves and deposits sediment, wearing down the Earth's surface. Water erosion is the process by which water wears down the Earth's surface, often leading to the formation of rivers, valleys, and canyons. Glacier erosion occurs when glaciers move across the Earth's surface, picking up and carrying rocks and sediment with them as they advance and retreat.
Where is debris found on a glacier?
Debris on a glacier can be found scattered on the glacier's surface, within crevasses, or concentrated at the glacier's margins. It can include rocks, sediment, and even man-made objects that have fallen or been carried onto the glacier.
What is a glacier flows over the land it picks up rocks in this process?
As a glacier flows over the land, it erodes the underlying rock and sediment through a process called abrasion. The immense weight and movement of the ice scrape and grind the surface, loosening rocks and debris. These materials become embedded within the glacier, which transports them over long distances. When the glacier melts, it deposits these rocks, contributing to the formation of various landforms and landscapes.

What does a glacier do to the surface of the earth as it recedes?
the glacier deposits various rocks and sediment it displaced as it moved forward
How does till form?
Formed when a mixture of sediments that a glacier deposits directly on the surface
How does a till form?
Formed when a mixture of sediments that a glacier deposits directly on the surface
Which type of erosion moves the most sediment on the earth's surface?
Glacier Erosion

Small hills that are formed from deposits left by streams on the surface of a glacier are called what?
Kames. Many are found in areas of kettles and moraines.
What are two ways glaciers erode Earths surface?
The glacier scrapes the surface of the earth as it advances, then deposits that till at its terminus when it melts.

How does change granite into sandstone?
Granite becomes Sandstone when water erodes the Granite on Earths surface, and then deposits the sediment.
