Is sediment part of a glacier system?
No, sediment is not part of a glacier system. Glaciers are made up of ice formed from compacted snow, and sediment is material that is eroded and transported by the glacier or deposited under the glacier. Sediment can become trapped in the glacier ice as it moves, but it is not considered as part of the glacier system itself.
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.
Is a glacier a sedimentary rock?
No, a glacier is not a sedimentary rock. A glacier is a large mass of ice that moves under its own weight, while sedimentary rocks are formed through the layering and cementation of sediment over time.
Does a glacier have mass movement?
Yes, a glacier exhibits mass movement as it flows under the influence of gravity. This movement occurs as the ice deforms internally and slides over the underlying bedrock or sediment. The process can result in the glacier advancing, retreating, or deforming, contributing to the landscape through erosion and deposition. Thus, glaciers are dynamic systems that continuously reshape their environment.
Features form when tension and compression build under the surface of a flowing glacier?
As glaciers move, the immense weight and pressure of the ice cause deformation in the underlying rock and sediment. Tension and compression build up beneath the glacier due to the flow dynamics, leading to the formation of features such as crevasses, ridges, and moraines. These features reflect the glacier's movement and the interactions between the ice and the landscape, revealing the complex processes at play beneath the surface. Ultimately, these geological formations provide insights into the glacier's history and behavior.

Which glacial does erosion takes place in?
Erosion primarily takes place in a glacier's zone of ablation, where the ice melts and water flows over and under the glacier, carrying sediment and debris with it to erode the bedrock below. Additionally, erosion can occur at the glacier's base due to the grinding action of the ice as it moves over the landscape.
What are the different types of glacial deposition?
The main types of glacial deposition are till, moraines, drumlins, eskers, and outwash plains. Till is unsorted sediment deposited directly by the glacier, while moraines are ridges of till deposited at the glacier's margin. Drumlins are smooth, elongated hills formed under glacial ice, eskers are winding ridges of sand and gravel deposited by meltwater streams, and outwash plains are flat areas of sorted sediment deposited beyond the glacier by meltwater.

Which is the first step in the process during the formation of molded fossils?
Organisms are buried under sediment.
What happens to the ground underneath a glacier as it moves and melts?
As a glacier moves and melts, the ground underneath it can become smoothed and shaped by the pressure and movement of the ice. This process is known as glacial erosion, and it can create features like valleys, ridges, and lakes. Additionally, as the glacier melts, it can deposit sediment and rocks, forming landforms like moraines and eskers.
What is crevasse and how does it form?
A crevasse is a deep open crack in a glacier. It is formed when a magma chamber under a glacier causes melting and cracking and causes the glacier to slide into the ocean on the magma
What country lie under a continental glacier?
Greenland & Antarctica.
How much area of siachen glacier is under Pakistan control?
NONE OF THE AREA OF ACTUAL GLACIER IN UNDER PAKISTANI CONTROL. The whole 70 Km long glacier is captured by India with Indian Troops present all over it including the top heights. Pakistan just has control on the valley.
