A glacier forms in an area where more snow falls than?
A glacier forms under certain terrain conditions and where more snow falls in the winter than melts in the summer.
How does a glacier grow?
A glacier grows when more snow accumulates in the glacier's area than melts or evaporates. This excess snow compacts into ice over time, causing the glacier to advance and thicken. The process is slow and can take many years or decades for a glacier to visibly grow in size.
What condition is most important to the growth of glaciers?
The most important condition for the growth of glaciers is a balance between snow accumulation and snowmelt. When more snow falls in a glacier area than melts during the summer, the glacier can grow and advance. Temperature and precipitation patterns also play a significant role in glacier growth.
What is a confined glacier?
A confined glacier is a glacier that is confined by topography. For example, a glacier that forms on a mountain. Continental glaciers, by contrast, are not affected. The glaciers on Antarctica and Greenland are continental glaciers. The glaciers at Glacier Bay National Park, or on a mountain are confined glaciers.
How is a glacier formed the melting and refreezing of snow the weathering and erosion of snow the erosion and deposition of ice the melting and precipitation of snow?
A glacier is formed through the accumulation of snow that compresses into ice over time. As more snow falls and compacts, it displaces air and forms glacial ice. This process is aided by the weight of the overlying snow, which causes the lower layers to compress and recrystallize into ice.
What is a Continentail glacier?
The Continentail glacier are the largest glacial bodies which are several kilometers deep and cover a large area of more than thousands of kilometers. There are only two continental glaciers the one which covers most of the area of Antarctica and Greenland.
Snowfall and its relation to glacier size?
Glaciers form where more snow falls than melts. So, it really depends where the glacier is. If the area snows like crazy a lot, the size of the glacier would be big. If it doesn't snow that much there, the glacier would probably melt much faster, and be less big.
What is a growing glacier different from a melting glacier?
A growing glacier accumulates more snow and ice each year, leading to overall glacier advancement. In contrast, a melting glacier loses more ice and snow than it gains, resulting in glacier retreat.
What example of water transferring from the atmosphere to the cryosphere?
In New Zealand there are Franz Josef glacier and Fox glacier In the French Alps there is the Mer de Glace The largest glaciers in the world are the ice sheets on Greenland, the second largest glacier in the world, and the ice sheet on Antarctica is the largest in the world. glaciers are riveres of ice that moves very slowly.
True or false When a glacier is retreating the upstream ice is still moving forward toward the downstream terminus of the glacier?
True. Even when a glacier is retreating, the ice in the upstream area continues to flow towards the downstream terminus. The retreat is due to the melting happening at a faster rate than the glacier is moving forward.
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.
What is more ancient a glacier or an iceberg?
A glacier is older than an iceberg, because an iceberg is a piece of ice that fell off a glacier.
