The Arctic ice cap consists of sea ice and the Greenland ice sheet . Sea ice can be several meters thick, while the Greenland ice sheet is several thousand feet thick in the interior.
Sea ice and ice sheets are two entirely separate things. The main being that ice sheets are formed from accumulated snow and are therefore entirely fresh water, while sea ice is frozen sea water. However, any salt that gets frozen into the ice - which itself is trapped in brine (liquid) pockets rather than incorporated into the crystalline structures - drains out with time.

Why is it important to save antarctica?
As it near to Australia, that government exudes a protectorate over a slice of the continent, which is held in abeyance by the Antarctic Treaty (1960).
What is the name of the thick layer of ice and snow that has formed permanent crust over Alaska and antarctica?
The ocean waters freeze in winter. This is referred to as sea ice. Ice in the form of glaciers being pushed out over the ocean is called an ice shelf.
How much has the ozone over antarctica been reduced?
The ozone over Antarctica has been reduced significantly. The reduced ozone is of the size of Australia.
The continent above which there is a hole in the ozone layer?
The ozone hole is largely over the continent of Antarctica, but it sometimes covers parts of Australia and South America.
What is causing a hole in the ozone layer over Antarctica?
The ozone hole is formed over Antarctica. It is because the ozone depletion takes place only where the temperature is very low.

Where are the polar ice caps?
Polar ice caps are high latitude regions that are covered in ice. Since for ice to form there has to be specific temperature ranges polar ice caps form only in very cold environments such as the North Pole (over water only), Greenland and Antarctica.
When you fly over over antarctica where are you?
You are over Antarctica in an airplane, probably.
Why is Antarctica's climate important to other parts of the world?
Antarctica is called the Earth's heat sink, which attracts excess heat from all over the planet.
Why don't seals get snow blindness?
Because they have thick layers over their eyes which prevent them getting blinded.However we are not made to live in Antarctica so we get snow blindness.
Where is the thickest ice in the world?
My mum said it was 'Greater Antarctica' but I don't know. Search the Internet if your not sure. You should know the answers anyway.
How did earths climate change in the Quaternary period?
thick continental glaciers advanced and retreated over parts of Europe and North America causeing it to be cold.sorry for the crappy spelling ;)
If you fly straight south from Chicago over what countries in South the US will you pass?
If you fly straight south from Chicago, you will pass over parts of Mexico, Honduras, and Nicaragua, and then no more land until you reach Antarctica. If you keep going, under the south pole and back up the other side, you will pass over more of Antarctica, then over a small island that belongs to India, and then over parts of Myanmar, Bangladesh, more of India, China, Mongolia, and Russia.
Why is the ozone hole larger in Antarctica with not near as many greenhouse gases as say in New York or Chicago?
The ozone hole is larger over Antarctica. It is because CFC's carried in various parts are carried to poles by westerly's.
Which of these statements describes a limitation of the Antarctic Treaty System?
It does nothing to protect the atmosphere over Antarctica.
What kind of an animal is a terrapin?
deep waters and in many parts of Antarctica
What percentage of Antarctica is owned by the UK?
None. UK makes claims over parts of the Antarctic continent, but the claims are not valid according to the Antarctic Treaty.
