∙ 10y agoThe zone of fracture experiences tension hen the glacier moves over irregular terrain. This tension results in gaping cracks called crevasses. Crevasses can be 50 meters deep. They are often hidden by snow and make travel across glaciers dangerous.

∙ 10y agoCrevasses form on the upper portion of the glacier because when a glacier moves over irregular terrain, the zone of fracture is subjected to tension, which forms the crevasse. The reason why it may not form below the depth of 50 feet is because plastic flow seals them off.
False. A glacier will move due to the force of gravity, not friction.
You can with the fastest moving glaciers in the world. For example, Jakobshavn in western Greenland advances about 20 meters per day.
Maybe. 112m is just the average, but here is the break down: 4.66 meters/hour 7.8 cm/minute 1.3 mm/second What do you think?
Slope and temperature play a very important role here, the steeper the slope and the higher the temperature, the easier the glacies flows. That being said, a glacier typically starts to flow when it reaches a thickness of between say 50 and 200 meters, depending on slope and temperature. The speed at which it flows is then several meters per year to several tens of meters per year, again depending on slope and temperature.
Crevasses form on the upper portion of the glacier because when a glacier moves over irregular terrain, the zone of fracture is subjected to tension, which forms the crevasse. The reason why it may not form below the depth of 50 feet is because plastic flow seals them off.
The area of Sperry Glacier is 874,120.9872384 square meters.
According to its Wikipedia entry: "Lambert Glacier is a major glacier in East Antarctica. At about 60 miles wide, over 250 miles long, and about 2,500 m deep, it holds the Guinness world record for the world's largest glacier."
The Bering Glacier is the largest (5200 sq km) and longest (190km) glacier in North America. It is 800 meters thick
It will take 57 years, so it will meet it in 2067.
The world's largest glacier is the Lambert glacier in Antarctica , according to the United States Geological Survey.The glacier is more than 60 miles (96 km) wide at its widest point, about 270 miles (435) long, and has been measured to be 8,200 feet (2,500 meters) deep at its center.
Once snow and ice reach more than 30 to 40 meters gravity begins to pull the glacier downhill.I hope I helped you!!! =)
The average thickness of glaciers decrease every year due to global warming and the melting of the polar ice caps. The average thickness of the Himalayan glacier is 85 and 175 meters thick.
Lambert Glacier is the world largest Glacier. It is in East Antarctica.The Baltoro Glacier, at 62 kilometers long, is one of the longest glaciers outside the polar regions. It is located in Baltistan, in the Gilgit-Baltistan Pakistan. The Lambert Glacier, located in East Antartica, is the largest on Earth. 250 miles (400 km) long, 60 miles (100 km) wide, and 2,500 meters deep.
