What is the difference between arctic ice and Antarctic ice?

What is the difference between arctic ice and Antarctic ice?

The primary difference between the Arctic and Antarctica is geographical. The Arctic is an ocean, covered by a thin layer of perennial sea ice and surrounded by land. Antarctica, on the other hand, is a continent, covered by a very thick ice cap and surrounded by a rim of sea ice and the Southern Ocean.

Is it true that 3 of ice in Antarctica is penguin urine?

TIL nearly 3% of the ice in Antarctic glaciers is penguin urine.

Why is it called pack ice?

Unlike fast ice, which is “fastened” to a fixed object, drift ice is carried along by winds and sea currents, hence its name. When drift ice is driven together into a large single mass (>70% coverage), it is called pack ice.

What is an ice pack in the ocean?

Pack ice, also known as ice pack or pack, any area of sea ice (ice formed by freezing of seawater) that is not landfast; it is mobile by virtue of not being attached to the shoreline or something else. See also sea ice.

Can you pee in Antarctica?

In Antarctica, you can’t pee wherever you’d like, due to environmental protection laws. We can only pee, or dump our pee, in designated areas, marked with a ‘pee flag.

What is a floating piece of ice called?

Icebergs are chunks of floating ice that have “calved” (broken off) from a glacier. Since they are formed from compacted snow, they are composed entirely of fresh water, like big floating ice cubes. Since 90% of an iceberg is below the surface of the water, they travel with ocean currents and not the winds.

What is ice floe?

An ice floe is a large pack of floating ice often defined as a flat piece at least 20 m across at its widest point, and up to more than 10 km across. Drift ice is a floating field of sea ice composed of several ice floes. They may cause ice jams on freshwater rivers, and in the open ocean may damage the hulls of ships.
