Two significant features of ice crystals in glaciers are their crystalline structure and the ability to deform under pressure. The crystalline structure allows for the formation of distinct ice types, influencing the glacier's flow behavior. Additionally, as ice crystals are subjected to pressure from overlying snow and ice, they can undergo plastic deformation, enabling glaciers to move and reshape the landscape over time.

Are glacial ice a sediment transporting agent?
Yes, glacial ice is a significant sediment transporting agent. As glaciers move, they erode rocks and soil, incorporating these materials into the ice. When glaciers advance or melt, they deposit the sediments they have collected, creating features like moraines and outwash plains. This process plays a crucial role in shaping landscapes and redistributing earth materials.
What are the different types of glaciers?
Ice Sheets Ice Shelves Ice Caps Ice Streams/Outlet Glaciers Icefields Mountain Glaciers Valley Glaciers Piedmont Glaciers Cirque Glaciers Hanging Glaciers Tidewater Glaciers
How is it possible for ice to flow?
Ice can flow due to the pressure exerted on it by its own weight, which causes the ice crystals to deform and slide past each other. This flow of ice is known as glacial flow and is a characteristic feature of glaciers and ice sheets. Over time, the ice can move downhill in response to gravity, forming glaciers that shape the landscape.
What is the slow movement of glaciers in which ice crystals slip over each other?
The slow movement of glaciers, where ice crystals slip over each other, is known as "glacial flow" or "glacial creep." This process occurs due to the pressure and weight of the overlying ice, which causes the ice at the base to deform and flow. This movement is influenced by factors such as temperature, the slope of the glacier, and the presence of meltwater, which can act as a lubricant. Glacial flow is a key factor in shaping the landscape, as glaciers carve out valleys and transport sediment.
What are giant glaciers called?
Giant glaciers are called ice sheets. These massive expanses of ice cover large areas of land and are found in Antarctica and Greenland. Ice sheets can be several kilometers thick and have a significant impact on global climate.
What is the size of ice crystals?
The size of ice crystals can vary significantly depending on the conditions under which they form. In clouds, ice crystals typically range from a few micrometers to several millimeters in diameter. In larger ice formations, such as glaciers or snowflakes, ice crystals can grow to sizes of several centimeters. Factors like temperature, humidity, and atmospheric pressure influence the growth and size of these crystals.
What are 4 effects of ice age glaciers from the formation of major erosional and depositional features?
what is the answer
Why are glaciers blue?
Glaciers appear blue because the dense ice absorbs red and yellow light, reflecting blue light. This happens because ice crystals scatter light in a way that makes the glacier look blue to our eyes.
Which continents was covered by glaciers during the Pleistocene ice age?
During the Pleistocene ice age, glaciers covered large parts of North America, Europe, and Asia. These glaciers were extensive and had a significant impact on the landscape and climate of these continents.

What percent of water occurs as ice sheets and glaciers?
Approximately 68.7% of the Earth's fresh water is stored in ice sheets and glaciers. This significant portion is primarily found in Antarctica and Greenland. When considering all water on Earth, ice sheets and glaciers account for about 1.7% of the total water volume.
What nation is called Land of Fire and Ice because of its geysers and glaciers?
Iceland is known as the Land of Fire and Ice because it has a combination of active volcanoes and glaciers. The geothermal activity in Iceland results in geysers and hot springs, while its glaciers cover a significant portion of the country.
Where is most earth's freshwater located?
Most of Earth's freshwater is located in glaciers and ice caps, accounting for about 68.7% of the total freshwater on the planet. Other significant sources include groundwater (30.1%) and surface water such as rivers and lakes (0.3%).
