Do lines of latitude meet at the south pole?

No. Just like parallel lines on a flat surface, any two lines of latitude that you

choose are the same distance apart everywhere, they never cross, and they

never touch. That's why they're often called "parallels" of latitude.

Does the Antarctic Region near the South Pole get colder than the Arctic Region near the North Pole?

Yes, the Antarctic Region near the South Pole generally experiences colder temperatures than the Arctic Region near the North Pole. This is due to various factors such as higher elevation of the Antarctic ice sheet, which promotes colder conditions, as well as differences in ocean currents and sea ice extent in the two regions.

How would the reduction of sea ice affect the wildlife of antarctica?

When the sea ice melts, and carnivore marine animals can come closer to the beaches, there are sea birds breeding on the beaches (no animals live on Antarctica0. Their offspring and some adults become food for the carnivore marine animals.

What might be the effect of sprinkling black soot over the ice in the Arctic and Antarctica?

This would alter the snow-albedo feedback. Darkening the surface of snow/ice greatly lowers the albedo (reflectivity) of the surface. This would cause the snow/ice surface to absorb more solar radiation by virtue of its lower albedo, which would allow it to heat up more.

Normally most solar radiation is simply reflected by snow back into the atmosphere and mostly out to space, so by causing it to absorb more you are heating up the lower atmosphere. By doing this, you are more likely to melt the snow/ice, whereby the albedo will be even lower, which would then absorb more radiation, etc.. This is called a positive feedback loop.

Why is Antarctica covered in ice and snow?

Antarctica is a continent like every other continent on earth. Precipitation falls from clouds in the sky. In Antarctica, which is a polar desert, most precipitation evaporates. The moisture that falls to the earth is frozen into ice crystals.

What is a very dry climate with little precipitation?

Hot dry summers with most of the precipitation occurring in late spring to early summer, and cold snowy winters. This is different for an African veld/savannah, however, which experiences 4 to 6 months of extreme drought and 6 to 8 months of violent thunderstorms that produce massive amounts of rain.

What continent is located nearest 80 degrees south latitude?

Antarctica is the continent located nearest to 80 degrees south latitude. At this latitude, the majority of the continent is covered by the vast Antarctic ice sheet, making it the southernmost continent on Earth.

What is the continent of North Pole?

The North Pole is not on any continent. It is an imaginary point on the Earth's surface that can be reached by travelling over the Arctic Ice Sheet, which forms on the surface of the Arctic Sea.

What is the annual temperature range in Antarctica?

Average temperature:

The average temperature in Antarctica is -50°C (-58°F).

Annual rainfall:

It does not rain in Antarctica because it is so cold and water vapor is frozen out of the air. Although it does not rain, precipitation DOES occur in the form of frost and occasional light snowfall. The interior averages about 2 inches (50 mm) a year, making Antarctica a desert.

What is the average thickness of pack ice?

The ice thickness depends on season. In the antarctic sea, practically all sea-ice melts in the antarctic summer (keep in mind that antarctic land is covered by deep glaciers all year).

In the arctic, in summer the ice thins. It used to retain an average thickness of a few meters, but in the past few years it thinned. On Aug 16 2010 PIOMAS published an ice volume of about 5 million cubic meters (they actually published an anomaly of about -9.7 from the 1979-2009 average of 14.7). For that date, the

Arctic Climate Research at the University of Illinois published an area of about 4 million square meters (a few thousand more) so it gives about 1.25 meter average depth. Note that PIOMAS is only using a validated model plus some measurements, as there are no global direct measurements (seems there will be next year). Expect to see more numbers at end of September, as the minimum of arctic sea-ice is around mid-Septrmber.

What is north of Antarctica?

Everything on earth is north of Antarctica.

What would the world look like if sea levels rise?

  • Coastal areas all over the world will be flooded.
  • All beaches will be destroyed.
  • Low lying Pacific Island countries will be finished.
  • High tides will swamp London and New York.
  • Holland will be under water.

What are the differences between Antarctica and North America?

North America is land and is up north, but Antarctica is ice and is down south. Millions live in North America, but not very many live in Antarctica. North America's summer is Antarctica's winter, and North America's winter is Antarctica's summer! Also, North America is much bigger than Antarctica.

Is south pole a continent?

No, the south pole is not a continent, but a compass point: 90 degrees South Latitude. It exists on a continent named Antarctica.

How far does the sea ice extend around Antarctica?

Your answer depends on the time of year when you want to measure the ice.

In winter, the sea ice freezes and almost doubles the size of the Antarctic continent. The edges of the ice are ragged and change, depending on the action of the liquid sea.

Is Antarctica and the Alps the same thing?

No, Antarctica and the Alps are not the same thing. Antarctica is a continent covered in ice and located at the South Pole, while the Alps is a mountain range in Europe. They are two distinct geographical regions.

What two climate zones are found in Antarctica?

There are actually several climate zones in Antarctica. They are:

  • Continental High Plateau - extreme cold year round
  • Continental Low Plateau - very cold year round
  • Continental High Latitude Coast - cold winters and short, cold summers, frequently changing weather
  • Continental Low Latitude Coast - cold winters and short, cold summers, precipitation can be heavy, winds can be very strong
  • Antarctic Peninsula - Fairly typical maritime climate - cold winters and warmer summers
  • Antarctic Islands - Similar to Antarctic Peninsula, but milder
  • Sub-Antarctic Islands - Oceanic climate - cool summers and cooler winters

What is located at 90 south latitude?

90 degrees north latitude is a single point, referred to as the "north pole".

We leave it to you to reflect on this fact, and then to speculate on what the common label

might be for the point defined by 90 degrees southlatitude.

What does a meteorologist do in antarctica?

A Meteorologist keep a log of data such as temperatures, wind speed and direction, pressure and pressure changes, weather description, snow, blizzards etc at three hour intervals. Twice a day we release a balloon with a transmitter tied to it which sends back temperature, pressure and humidity values every 10 seconds until the balloon bursts at about 28 kms up - about 90 minutes after release. It's a GPS transmitter so we get wind data as well.

What is Antarctica made up of besides ice?

Answer

Unlike the arctic region in the north, Antarctica is a continent. It is land, and there are actually some exposed sections of the land. Most of the continent is covered by thick ice sheets. Any ice in the Arctic region is floating on water.

Why is Antarctica a good place to study the weather?

Antarctica's weather is very cold and its lowest temperature ever recorded was -89.2 degrees Celsius. Antarctica is a great place for people such as meteorologists to study weather. Weather balloons are use to find weather temperatures and speeds. It is a good place for weather study because it has more different weather changes than most other parts of the world, and since it is located at the bottom of the Earth it has different view and direction to the sun. And of course its weather patterns are different, just like all parts of the world.

How much land is available for plant growth in antarctica?

There is very limited land available for plant growth in Antarctica, as most of the continent is covered by ice. Only a small percentage of the Antarctic Peninsula and nearby islands have areas where plants can grow, primarily mosses, lichens, and some grasses. These plants are adapted to the extreme cold and harsh conditions of the region.

Is is warmer inland or in the coast of antarctica?

It is generally warmer inland in Antarctica compared to the coast. This is because the coast is influenced by the cold waters of the Southern Ocean, which can keep temperatures lower than those further inland where the cold air is not moderated by the ocean.

In the Antarctic how much snow does the interior get each year?

The high interior of Antarctica gets very little snowfall (50 mm or 2 inches a year).

The average snowfall over the whole continent is around 166 mm (6.5 inches) per year, and parts of the Antarctic Peninsula receive more than 600 mm (2 feet).

The ocean that extends from Antarctica to 60 degrees south latitude is what ocean?

The ocean that extends from Antarctica to 60 degrees south latitude is the Southern Ocean. It is the newest recognized ocean, officially designated by the International Hydrographic Organization in 2000. It surrounds Antarctica and is known for its strong currents and cold waters.
