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.
How are stars on the upper left end of the main sequence different from those on the lower right end?
The main sequence is a map of star brightness against their temperature. Stars that lie on the main sequence in the top left are the high mass stars. Cooler, smaller stars lie near the line at the lower right.
What is the top of a space shuttle called?
The big fat end point
Could there be an apocalypse in the future?
well from what the bible has implied. the end is still yet to come, but it not the end, it is known to be called JUDGEMENT DAY.
How does a hanging valley cirque arete and a horn form?
A hanging valley forms when a smaller glacier flows into a larger glacier, leaving the smaller valley elevated above the main valley floor after the larger glacier retreats. A cirque is created by the erosion of a mountain side by a glacier, resulting in a bowl-shaped depression. An arete is a sharp ridge formed between two cirques that erode toward each other. A horn is a pointed mountain peak that results from the glacial erosion of multiple cirques surrounding a summit, sharpening it into a distinctive shape.
The end or outer margin of a glacier?
The end or outer margin of a glacier is called the glacier terminus. This is where the glacier ends and begins to melt or calve into the surrounding environment, such as a body of water or land. Changes in the glacier terminus are closely monitored by scientists to understand the health and movement of the glacier.
What is a glacier snout?
A glacier snout is the terminus or end point of a glacier where ice and meltwater are released. It is where the glacier meets lower elevations and warmer temperatures, causing melting and ice loss. The snout can vary in shape and size depending on the glacier's dynamics.
What is the material called that is deposited by melt-water beyond the end of a glacier?
The material deposited by meltwater beyond the end of a glacier is called moraine. This sediment consists of a mixture of rocks, gravel, sand, and silt that was transported and deposited by the glacier as it melted.
What is the ridge at the end of the glacier?
The ridge at the end of a glacier is called a terminal moraine. It forms when debris and sediment that were carried by the glacier accumulate and are deposited at the glacier's snout as it melts and retreats. Terminal moraines can help mark the furthest extent of a glacier's advance.
The lower portion of a glacier where there is an annual loss of ice due to melting?
That area is known as the ablation zone, where the rate of melting exceeds the rate of snow accumulation. It is located at the lower end of the glacier and is crucial in determining the overall health and size of the glacier.
The end of a valley glacier is at a lower elevation than its point of orgin is. how does this help explain melting at its end while snow and ice still are accumulating where it originated?
The end of a valley glacier, or terminus, is at a lower elevation where temperatures are generally warmer, leading to increased melting. Meanwhile, at the glacier's origin, which is at a higher elevation, temperatures are cooler, allowing for continued snowfall and accumulation of ice. This elevation gradient creates a balance where the glacier can still gain mass at its source while losing mass at its lower end due to melting. Thus, the combination of elevation and temperature differences explains the contrasting dynamics at different points along the glacier.
What is the material called that is deposited by meltwater beyond the end of a glacier?
The material deposited by meltwater beyond the end of a glacier is called glacial outwash or outwash plain. It consists of sediments such as sand, gravel, and boulders that have been carried by the flowing meltwater and deposited as the glacier retreats.
What is the moraine called that marks the farthest advance of a glacier?
The moraine that marks the farthest advance of a glacier is called a terminal or end moraine. It forms from the accumulation of debris and sediment that the glacier pushes forward as it advances. Once the glacier retreats, this moraine remains as a distinct ridge or hill, indicating the maximum extent of the glacier's reach.
What is the place where the glacier stopped moving and dropped the rocks and dirt it was carrying called?
The place where a glacier stops moving and deposits the rocks and dirt it was carrying is called a terminal moraine. These ridges of debris mark the furthest extent of the glacier's advance.
Ridges that form along the sides of glacial valleys as a glacier melts are called what?
Ridges that form along the sides of glacial valleys as a glacier melts are called moraines. Specifically, lateral moraines are found along the edges of a glacier, while terminal moraines accumulate at the glacier's end. These features are composed of debris and sediment that the glacier has transported and deposited as it advances and retreats.
What is the material called that is deposited by melt waterbeyond the end of the glacier?
The material deposited by meltwater beyond the end of a glacier is called "outwash." This sediment is typically composed of sand, gravel, and silt, which is carried away from the glacier by meltwater streams. Outwash is often arranged in stratified layers due to the varying flow of water, and it can form features like deltas or outwash plains.
What is zone of wastage?
The zone of wastage refers to the area of a glacier where more ice is melting or sublimating than is being replenished by snow accumulation. It is typically at the lower end of a glacier where temperatures are warmer, causing increased melting.
