Antarctica is the coldest place on Earth. It is a frozen
continent covered in ice. The South Pole is on Antarctica. The
South Pole is the farthest south that you can go!

Antarctica is very windy. It is also very dry. Antarctica is so
dry that scientists call it a desert. The small amount of snow that
falls there never melts. It is moved around by the wind until it
freezes into ice.

Few people other than scientists have been to Antarctica. It
costs a lot of money to send food and supplies there. But penguins,
seals, fish, and whales live there year-round.

Scientists study the weather in Antarctica. They use a radio
called an acoustic sounder. It sends beeping sounds high up into
the air. The beeping sounds make an echo that tells scientists the
wind’s speed and direction.

Satellites help scientists study the weather in Antarctica.
Weather information from the satellites is sent down to Earth.

Scientists in Antarctica also study the weather with balloons.
Each day, they launch the balloons into the air. Radios attached to
the balloons record information about the air.

Scientists are learning about global warming on Antarctica.
Global warming happens when air pollution traps heat inside the
Earth’s atmosphere. Some parts of Antarctica have become warmer.
Other parts are growing colder.
A model showing how air pollution traps heat from the sun.
Warmer air could cause the ice to melt.

Emperor penguins spend their whole lives in Antarctica. Penguins
cannot fly. But they are very good swimmers. They use their feet
and flippers to swim. Penguins use their bills to preen, or clean
and smooth their feathers.

Female emperor penguins lay one egg. The male emperor penguin
takes care of the egg. He snuggles and cuddles the egg with his
feet. Soon the chick is ready to hatch. It pecks at the shell until
it breaks.

For emperor penguins, seals, fish, and whales, the climate in
Antarctica is just right. Scientists will continue to study
Antarctica’s climate and watch for signs of change. In this way
they are protecting the animals that make their home there.
