Quick Answer: Why Do The Arctic And Antarctic Ocean Remains Frozen For Many Months Of The Year?

Do polar bears live in Antarctica?

Polar bears live in the Arctic, but not Antarctica.

Down south in Antarctica you’ll find penguins, seals, whales and all kinds of seabirds, but never polar bears.

Even though the north and south polar regions both have lots of snow and ice, polar bears stick to the north.

Polar bears don’t live in Antarctica..

Why is Antarctic sea ice increasing?

Changes in atmospheric dynamics and winds are an important driver of regional sea-ice trends. Ozone and greenhouse forcings cool the Antarctic stratosphere, which increases the stratospheric vortex and tropospheric zonal winds. This results in an increase in the Southern Annular Mode [6].

Is Arctic sea ice really declining?

Sea ice in the Arctic has decreased dramatically since the late 1970s, particularly in summer and autumn. Since the satellite record began in 1978, the yearly minimum Arctic sea ice extent (which occurs in September) has decreased by about 40% [Figure 5].

What are the 7 Seven Seas?

The Seven Seas include the Arctic, North Atlantic, South Atlantic, North Pacific, South Pacific, Indian, and Southern Oceans. The exact origin of the phrase ‘Seven Seas’ is uncertain, although there are references in ancient literature that date back thousands of years.

What is the hottest ocean on Earth?

Persian GulfAnswer: The hottest ocean area is in the Persian Gulf, where water temperatures at the surface exceed 90 degrees Fahrenheit in the summer. Another hot area exists in the Red Sea, where a temperature of 132.8 degrees Fahrenheit has been recorded at a depth of about 6,500 feet.

Why do the Arctic and Antarctic oceans remain frozen for many months of the year?

Land Ice. Glacial ice forms on land, and is made of freshwater snow packed down tightly over many years. … The Greenland and Antarctic ice sheets are the only ice sheets currently on Earth, and they contain 75 percent of the freshwater in the world. When ice sheets grow and move out over the ocean they form ice shelves.

Are there sharks in Antarctica?

These species, which are frequently found in shallow water, would struggle crossing the deep ocean surrounding the southernmost continent. Thus, no sharks in Antarctica… yet. Antarctic seawater temperatures are on the rise, and with this rise comes new visitors.

Are there any dinosaurs frozen in ice?

In the icy badlands of Alberta, paleontologists have found a “frozen dragon”: a new genus of pterosaur that once soared over the heads of dinosaurs with a wingspan that stretched at least 16 feet.

Will Antarctica melt?

Antarctica is already losing more than 200 billion tons of ice each year. … But scientists suspect that surface melting may cause greater losses in the future as the ice sheet continues to warm. For now, scientists don’t think that atmospheric rivers are actually causing that much mass loss in Antarctica.

What would happen if Antarctica melted?

If all the ice covering Antarctica , Greenland, and in mountain glaciers around the world were to melt, sea level would rise about 70 meters (230 feet). The ocean would cover all the coastal cities. And land area would shrink significantly. … However, all the ice is not going to melt.

Why is the Arctic warming faster than the Antarctic?

In winter, the Arctic Ocean, which covers the North Pole, is covered in sea ice and that sea ice has an insulating layer of snow on it. … As temperatures rise in spring, sea ice melts, exposing the dark ocean underneath, which absorbs even more solar radiation, increasing warming of the region, which melts even more ice.

Why is the Arctic always frozen?

Both the Arctic (North Pole) and the Antarctic (South Pole) are cold because they don’t get any direct sunlight. The Sun is always low on the horizon, even in the middle of summer. In winter, the Sun is so far below the horizon that it doesn’t come up at all for months at a time. … The Arctic is ocean surrounded by land.

How long has the Arctic been frozen?

The polar ice caps melted for a while after that and it wasn’t until Africa and Antarctica separated around 160 million years ago that it began to cool again. By 23 million years ago, Antarctica was mostly icy forest and for the last 15 million years, it has been a frozen desert under a thick ice sheet.

What is the coldest sea on earth?

Arctic OceanThe Arctic Ocean is the smallest and shallowest of the world’s five major oceans. It spans an area of approximately 14,060,000 km2 (5,430,000 sq mi) and is also known as the coldest of all the oceans.

Was Antarctica a jungle?

Scientists have discovered remnants of a swampy temperate rainforest that thrived in Antarctica about 90 million years ago. … Ninety million years ago, this West Antarctic forest was just 560 miles (900 km) from the then-South Pole. Yet its climate was surprisingly mild.

Is Antarctic ice growing or shrinking?

According to climate models, rising global temperatures should cause sea ice in both regions to shrink. But observations show that ice extent in the Arctic has shrunk faster than models predicted, and in the Antarctic it has been growing slightly.

Which ocean is the most dangerous?

The South China Sea and East Indies, eastern Mediterranean, Black Sea, North Sea, and British Isles are the most dangerous seas in the world, with the greatest number of shipping accidents in the last 15 years, according to a report released by the World Wildlife Fund (WWF).

Where is the hottest place on earth?

Scientists still have to validate the reading of 130 degrees Fahrenheit on Sunday, the equivalent of 54 degrees Celsius. In the popular imagination, Death Valley in Southern California is the hottest place on earth.
