THE ARCTIC: THE COLD BIOME
Transcript of THE ARCTIC: THE COLD BIOME
BY: CJ CORALEJO, CHRISTOPHER RENOIS, & KHARY GONZALES
WHERE IS THIS BIOME LOCATED?
This biome is located in the Northern Hemisphere.
This is where the Arctic is found, geographically speaking.
Best Time To Visit
The best time to visit you might be asking right now is....
ALL THE TIME!!!
PUBLIC PARKS & LANDS
Suprisingly, there is one National Park for the Arctic. It is located in Alaska and is the "Gates of the Arctic National Park."
TEST YOUR KNOWLEDGE OF THE ARCTIC
8 ABIOTIC FACTORS
Temperature of this biome (usually below freezing point)
Snow, hail, and other forms of precipitation (about 100 inches per year)
Seasons in the Arctic are naturally short. Summer doesnt last very long, but Winter lasts the longest.
The altitude in the Arctic is usually 1000 meters below snow mountains.
Winds in the Arctic blow at about 100 mph.
There is a pH salinity within the soil
Angle of the sunlight
Permafrost is noticeable in the Arctic since trees cannot grow there
There are some biotic factors that are present within the arctic. Such as some of the living organisms which impact the growth, composition, and structure.
Aquatic Arctic Moss (found in Arctic Lakes)
Lichens (composed of two organisms)
Arctic Willows (shallow roots to adapt to permafrost)
Tafted Suxifrage (can grow up to 5-10mm)
Pasque Flower (grows up to 6-8 inches off the ground)
Caribou Moss (usually grows to 4 inches)
FOOD WEB (SEA AND LAND)
Wolves > Caribou- The wolves hunt caribou for energy. The caribou sleeps on a frozen lake to protect itself from the wolves. Caribou sleep on the lake since it can see wolves from far away before they get in close and because the caribou can outrun wolves in the lake.
Polar Bears > Arctic Foxes - Polar bears eat the arctic fox for energy. The arctic fox follows the polar bear after eating so it can gather the polar bears leftovers. If found by the polar bear the arctic fox is then hunted down.
According to the WWF (World Wildlife) these are a few of the endangered species in the Arctic. The Polar Bear, the Sei Whale, the Narwhal, the Beluga Whale, and the Seal.
HUMAN IMPACT ON THE ENVIRONMENT
The species is in trouble due to recent human activity. When people mine for fossil fuels, it harms the environment as well as all the industrialization and gas that is in the population. This brings a negative impact on the environment, the plants, and the animals. Another impact is the fishing in the arctic.
A few positive impacts is that, due to the recent activity, the Arctic has become more known to be preserved since it is a very fragile biome.
Some negative impacts include pollution, climate change, and changes in biological diversity.
According to data and research of this biome, the Arctic (in my opinion) will slowly melt and increase the sea level within the Earth. Of course before this happens, the animals in this environment, will be transported somewhere else safe where they can accommodate to the environment and natural selection will take place. Also some of the animals from the environment will later adapt to this environment. Until then, the government will be trying to create an artificial "Arctic."
10 FUN FACTS ABOUT THE ARCTIC
Polar bears can only be found in the Arctic and are the largest land predator on Earth.
The Arctic Ocean is about 14 million square kilometres and is usually frozen.
Penguins, suprisingly don't live in the Arctic but south in Antarctica.
Iceland is the hot spot of the Arctic which had 30 glacial volcanoes erupt within the past 2 centuries. The volcanoes provide a pollution-free heat source.
Greenland is the second largest ice cap in the world. (85 % of the country is covered in ice which raises the sea level there up to 3000 m.)
The Arctic Ocean is the smallest of the five oceans. It is roughly 8% the size of the Pacific.
The Arctic Ocean is named after the Greek word "Arctos" which means "Bear" since you can see the Bear Constellation up above.
The water in the Arctic is usually about -30 degrees to -70 degrees Celsisus all year round.
The first crossing of the Arctic Ocean was made by Wally Herbert in 1969.
During long winters, the sun does not rise above the horizon for about 4 months straight. This phenomenon happens every year.
