ice is generally thicker in the middle of the lake once the lake completely freezes, as the edge of the land at the edge of the lake warms the waters edge making it thinner ice.
The thickest ice is found in East Antarctica. For example, Lake Vostok, a sub-glacial lake found in East Antarctica has a surface measured at -1,640.4′.
in the middle of the waters
water freezes from the outside to the inside. when a lake freezes, the top turns to ice first.
Ice melts faster on the outside. This is because there is ice surrounding the middle keeping it from getting warm.
Since not all parts of Antarctica have been mapped insofar as its ice sheet thickness is concerned, it may not be possible to identify the absolute thickest ice area. What we do know, however, is that the South Pole sits on ice that is at least 10,000 feet thick. As well, we know that the Vostok Research Station sits on ice that is more than 11,000 feet above mean sea level. As well, in the same area, Lake Vostok exists 13,000 feet under the surface of the ice,
8.5 feet
They are ice fishing!
30 degrees F because 30 degrees C is about 90 degrees F and you would not have much ice on the lake!
A lake which remains in a liquid form although it is covered with ice is called an ice covered lake.
because you dont know how thin the ice is. it might be really thin in the middle even if its thick on the outside. so if you walked on it and slipped in the middle, the ice might crack and you would be stuck in the middle of a freezing cold lake with no one around. you would either drown or cattch amnesia. dont walk or skate on frozen lakes. if you see someone fall in, don't run after them, throw them a rope or call an ambulance.
The ice is extremely thick, I believe getting to 3km thick at the thickest
The Laurentide Ice Sheet was thought to be two miles (3.2 km) thick around Nunavik Canada.
