How much of earths is covered by water?
Roughly 75% of Earths Surface is covered by water. (including the Oceans, lakes and land Ice).
How much area does ice occupy on earth?
Approximately 70% of Earth's surface is covered by the oceans.
Why is the sealevel so low during ice age?
Ice is frozen water. It is evident that if a lot of the land is covered with ice then that ice had to come from somewhere. The only places it could come from are the oceans. Water evaporates from the oceans, it falls on high ground as snow and over time this compacts into ice. If water is being evaporated from the oceans and none is being returned then the water level drops.
Which one of the worlds oceans is most likely made of ice?
Well, all the world's oceans are made of water. The Arctic Ocean may be covered with ice for a few months at a time. But only a few m thick at most.
How much of Antarctica is hidden under a large ice sheet?
Ninety-eight percent of the continent is covered by ice.
How was the land bridge formed?
Land bridges aren't actually formed, they are already there but covered by the sea. When a glacial period starts, the water evaporated from the oceans falls as snow on the land and then compacts as ice which does not melt. Continual removal of water from the oceans over thousands of years causes sea level to drop and exposes the "land bridges".
How much of the earths land surface is permanently covered by snow and ice?
About 10.4% of the world's land surface (approximately 6,020,000 square miles (15,600,000 square kilometers))is glaciated (is covered with frozen ice).
What are similarities between ice ages and glaciers?
An ice age is when the whole world or large mass of land is covered with a sheet of ice, where as a glacier is a large sheet of ice over a smaller piece of land not causing global problems.
What large sheets cover Antarctica?
Ninety-eight percent of Antarctica is covered with an ice sheet.
What is a large mass of water covered in ice and snow that moves slowly down a slope?
a glacier
When large areas of continents are covered by ice what happens to the rate of chemical weathering?
they freeze to death
What age was very long period of time when glaciers covered large parts of the earth?
The ice age.
