Why do mountains gradually become smaller over time?
They gradually erode (wear away) due to the forces of nature. Air moves pieces of rock and loose chunks, Water washes away rock and loose chunks, Rocks make cracks in other rocks as they fall, and water seeps into cracks and breaks rocks off when it freezes, because ice expands when it freezes.
What the 2 most common kinds of glaciers?
There are 2 main types of glaciers, Continental is one, they float away from central regions. The second is alpine or valley which are the glaciers that flow down the valley from the mountain.
How is glacier a source of both weathering and erosion?
Glaciers move (very slowly) therefore functioning as a source of erosion. They are also a source of weathering "in situ" due to their freeze/thaw cycles causing expansion/contraction of adjacent stone, causing physical deformation.
Wear do icebergs come from?
Usually the north and south pole. they break away from the main iceland(north and south pole) usually caused by earthquakes, climate change, man-made bombs, etc.
Can people live on Glaciers?
It is not advisable for people to live on glaciers due to harsh living conditions, extreme temperatures, unstable ice formations, and the risk of avalanches and crevasses. Additionally, glaciers are constantly shifting and melting, posing additional dangers to human habitation.
What do you call massive chunks of the ice that breaks away from glaciers?
call a massive chunls of ice that breaks away from glaciers
How does a iceburg form?
Icebergs are formed when large pieces of ice break off of glaciers. These chunks of ice will begin to float away until they reach the ocean.
What is a glaciers that floats away in the ocean?
An iceberg is a glacier that breaks off from a glacier or ice shelf and floats away in the ocean. These large chunks of ice can be found in polar regions and are a common sight in Arctic and Antarctic waters.
What is the process of forming an iceberg called?
The process of forming an iceberg is called calving. This occurs when chunks of ice break off from the edge of a glacier or ice shelf and float away as icebergs.
What is the proccess by which glaciers make icebergs?
When a glacier flows into the sea, it breaks off chunks of ice at the edge, forming icebergs in a process called calving. The icebergs then float away from the glacier and into the open ocean.
How do icebergs work?
Icebergs are large pieces of ice that break off from glaciers or ice sheets and float in the ocean. Most of an iceberg is underwater, with only about 10% visible above the surface. They can be dangerous to ships because of their size and the potential for hidden, submerged ice.
In a process called plucking the rocks dragged by glaciers produce grooves and scratches in bedrock?
Plucking is a process where glaciers erode bedrock by lifting and removing chunks of rock as they move. As the glacier advances, the pressure and movement cause rocks to fracture and break away from the underlying bedrock. This action creates distinctive grooves and scratches, known as striations, which provide evidence of the glacier's flow direction. Such features are commonly observed in glacial landscapes and are important for understanding past glacial activity.
How are glaciers and erosion the same and different?
Glaciers and erosion are both natural processes that shape the Earth's surface over time. Glaciers, however, are large bodies of ice that flow slowly over land, eroding and reshaping the landscape through the movement and melting of ice. Erosion, on the other hand, refers to the process of wearing away and transporting rock and soil by natural forces like water, wind, and ice, and can occur in various forms beyond just glaciers.
Why did 5500 square kilometres of ice break away in Antarctica?
Icebergs break away from Antarctica regularly, because they are the glacial ice-river flows from its glaciers. When the bergs lose their 'land footing' and float into sea water do to this flow, soon enough the sea water's action breaks away the 'tongue' and an iceberg will float freely.
Why do mountains gradually become smaller over time?
They gradually erode (wear away) due to the forces of nature. Air moves pieces of rock and loose chunks, Water washes away rock and loose chunks, Rocks make cracks in other rocks as they fall, and water seeps into cracks and breaks rocks off when it freezes, because ice expands when it freezes.
What is the process of ice breaking in smaller pieces?
In reference to glaciers or icebergs,when smaller pieces break off and fall away,it is called "calving", as though the parent ice formation were having a calf.
How glacier weather and erode rock material?
Glaciers weather and erode rock material primarily through processes like abrasion and plucking. As glaciers move, the ice at their base contains rocks and debris that scrape against the bedrock, grinding it down through abrasion. Additionally, as glaciers advance, they can exert pressure on the underlying rock, causing fractures that lead to plucking, where chunks of rock are dislodged and carried away by the ice. This combined action reshapes the landscape, creating features such as valleys and fjords.
