What force moves a glacier downhill?
Glaciers can slide down slope for several reasons. First, a glacier is made of ice, which is frozen water. Liquid water is slippery. That is important to remember. Second, gravity is pulling on them making them want to move downhill. Third, when ice is put under a lot of pressure, it can melt. The pressure above the bottom of the glacier can cause some melting on the bottom layer. That can make the glacier slide. Fourth, the sun shining on the top of the glacier can make the top of the glacier melt. The water from that melting can go to the bottom of the glacier and help lubricate the bottom. That can help it slide. Mountain glaciers are always sliding downhill. Snow replenishes glaciers and adds ice to the top. If glaciers melt faster than they are replenished they vanish. Some mountain glaciers have vanished within the last 100 years. A few more are likely to vanish in the next decade.
Where does glacier ice move quickly and slowly within a glacier?
Glacier ice moves more quickly in the center of the glacier where there is less friction with the valley walls. It moves more slowly along the sides and bottom of the glacier where there is more friction with the rock and sediment beneath it.
The land left behind after a glacier passed through it would most likely become?
a U-shaped valley with steep sides and a flat bottom due to the erosion caused by the glacier. Once the glacier retreats, it will leave behind a variety of landforms such as moraines, drumlins, and kettle lakes.
In a process called blank a glacier scours the bedrock as it moves?
In a process called "abrasion," a glacier scours the bedrock as it moves, grinding away the surface and shaping the underlying rock through the friction of debris carried along by the glacier. This process helps to create glacial valleys, cirques, and other landforms shaped by glacial erosion.
Is there a layer of limestone at the bottom of a Kettle?
Kettles are glacial landforms that form when a block of ice is left behind by a retreating glacier and then melts. The presence of limestone at the bottom of a kettle would depend on the local geology of the area where the kettle formed. If the area has limestone deposits, it is possible for a kettle to have a layer of limestone at its bottom.
What happens when the top layers of a glacier move faster then the bottom layers?
you are so stupid
What happens when ther top layers of a glacier moves faster then the bottom llayers?
you are so stupid
Is the side and the bottom of a glacier weigh the least?
bottom is the heaviest
What moraines are abrasive elements carried bottom of a frozen glacier?
Ground Moraines are abrasive elements that are carried in the bottom of a frozen glacier. Lateral Moraines are unsorted material deposited along the side of a valley glacier.
Moraines carried in the bottom of glaciers?
Moraines carried at the bottom of glaciers are called basal or ground moraines. They consist of rocks, soil, and other debris that have been plucked and eroded by the moving glacier. Basal moraines are typically deposited at the glacier's terminus or along its path as the glacier retreats.
The process in which fragments freeze to the bottom of a glacier and then are carried away when the glaciers are moved is called?
The process in which rock fragments freeze to the bottom of a glacier and are then carried away when the glacier moves is called plucking. After the last ice age, stranded ice blocks left behind by the continental glacier melted and formed kettles.
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.
How can ice affect rocks?
The answer is...
What Moraines that are abrasive elements carried in the bottom of a frozen glacier?
grounds
Why does the top of a glacier move faster than the bottom?
The top of a glacier moves faster than the bottom because of the effects of gravity. As the glacier flows downhill, the ice at the top is able to slide over the layers beneath it, causing it to move quicker. This phenomenon is known as internal deformation.
What is the shape of a glacier valley?
A glacier valley typically has a U-shape, with steep sides and a flat bottom. This shape is the result of the erosion and scouring action of the glacier as it moves downhill, carving out the landscape over time.
What happens if the whole pond freezes will fish die?
If the water freezes but the pond is deep enough for the fish to still be in water at the bottom there is a good chance they will survive. If all of the water freezes however and the fish become frozen solid then I'm afraid they are unlikely to survive.
