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
What models the behavior of a solar prominence best?
a glacier melting slowly on a mountain top
The main sequence has a limit at the lower end because?
the main sequence has a limit at the lower end because as a star's mass decreases, its core temperature and pressure decrease too. This eventually causes the nuclear fusion reactions in the core to stop, leading the star to move off the main sequence.
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.
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 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.
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.
The largest glacier in Alaska is called?
malaspina glacier
What are terminal moraine?
Terminal moraines are ridges of glacial debris deposited at the furthest point reached by a glacier. They mark the end of a glacier's advance and can be seen as a line of debris and rocks left behind as the glacier melts and retreats. These moraines are called "terminal" because they are found at the glacier’s terminus.
What are rivers of ice?
A frozen river is called a frozen river. Rivers that normally flow as liquid water, are called frozen rivers when they become frozen.
When did Glacier Point Hotel end?
Glacier Point Hotel ended in 1969.
