The Antarctic Treaty
The Antarctic Treaty is an agreement to say that there will be no war, military, army, weapon testing or anything bad that can ruin the continent. The treaty was signed in Washington on the 1st of December 1959 by 49 countries. Twelve of these 49 countries originally signed the treaty. The twelve countries that were involved in the treaty are Australia, Argentina, Belgium, Chile, France, Japan, New Zealand, Norway, South Africa, the Soviet Union, the United Kingdom and the United States.
The future of Antarctica
I believe the future of Antarctica involves the treaty still being in force. I also believe that some of the ice will melt over time which means the water level will increase by approximately 60 metres.
I hope you enjoyed my prezi presentation!
There is a lot of flora in Antarctica
You probably didn't know that there are heaps and heaps of fauna in Antarctica.
I have a couple of animals in each category including...
When Emperor Penguins dive into the the water they can reach up to 17km per hour and can hold its breath for 20 minutes.
When a mother loses her chick she will actually attempt to steal another mother's chick but usually without success as they are fierce protectors of their young.
Emperor Penguins slide over the ice on their stomach to preserve energy. This is called tobogganing.
Mosses grow in most places around the world. You've seen them before, especially growing in or near streams or other wet places. There are many different types of mosses around the world. But, here in the Dry Valleys of Antarctica, there are only four species of moss. They are the only plants that grow in the soil.
Liverworts have a leafy appearance with yellowish-green, dark red-brown or black shoots that either lie along the ground or are raised upwards.
They have a glossy flat leafed appearance that's shaped in a Y. When dry these parts close together like a clam revealing just a black line on the surface. Liverworts are confined to wet spots like moss.
Lichens are not a single organism but are two different plants, a fungus and an alga growing together as a single unit. This type of teaming up between plants is known as symbiosis. Each has something to offer the other so that by living together the plants have worked out a mutual benefit. Lichens are slow growing and found in many climates from deserts to tropical rainforests to Antarctica.
Algae is mostly seen in the water.
There are more than 300 species of non-marine algae found in Antarctica. They grow in damp sand and gravel around lakes. The snow algae form colonies in colors of red, yellow or green in areas where snow is permanent.
The Leopard Seal
Leopard seals are named for their spotted coats, and are one of the primary predators of Antarctica. The pattern is similar to the famous big cat, though the seal's coat is grey rather than golden in colour. This seal is sometimes called the sea leopard. They use their powerful jaws and long teeth to kill smaller seals, fish, Squid and Penguins.
The Killer whale is the largest Whale in Antarctica and one of the worlds most powerful predator. They feast on marine mammals such as seals, sea lions, and even whales. They are known to grab seals right off the ice. They also eat fish, squid, and seabirds.
Icefish can survive temperatures from -2 to -40 degrees Celsius. These fish probably could not survive anywhere else, since they've spend millions of years adapting in this freezing cold water.
