● Arctic is the area around the North Pole. ● It consists of Arctic Ocean and parts of Canada, Russia, Greenland, Norway, United States, Sweden, Finland, and Iceland. ● The area of Arctic is 26 mil. km². ● Arctic is predominantly frozen. ● People living there are called Inuits.
● Arctic climate is affected by cold sea currents.Temperature ● In winter (in July) between -40°C and -70°C. ● In summer (in January) between -10°C and -40°C. ● Average tempature isn‘t higher than 10°C. Climate
Icebergs are formed by fresh water. It is very difficult to say how large the iceberg is because you can se only 1/10 of it. The rest is under water. Icebergs can be m high. The average weight of pack ice is and tons. The largest iceberg located in the North Atlantic was 168 m high. Iceberg caused one of the most famous maritime disasters: in April 1912 about 1500 passengers and crew members died when Titanic crashed into the iceberg.
1. CONTINENTAL The continental iceberg is only in the Antarctic and Greenland now. 2. FLOATING Gigantic piece of ice broken off the continental iceberg.
Arctic icebergs are the largest reservoir of fresh water in the world. The Arctic is also a unique natural system that balances the stability of the world's climate.
● Arctic deserts are frozen however we can find some plants in the south. There are mosses, lichens, algae, mushrooms and bacteria in the Antarctic Continent. Flora
We can also find some animals, especially penguins, seabirds, seals, plankton and lots of types of fish living there.
The melting of icebergs
!!! I cebergs are melting faster and faster: in 1996 in Greenland melted 63 km 3 of ice, in 2005 it already was 162 km 3 !!! !!! Polar bears, seals and walrus are in the danger of their life !!! !!! The temperature of water increased by 3 o C in the west of Arctic but fish need colder water !!! !!! The sea level is higher and higher. It can flood islands and land with a low altitude !!!
