15 DAD Worksheet Our Earth is an amazing place. On one hand, we have mountains that are never free of snow. On the other hand, we have deserts where it does not rain for days. Again, there are places where it rains every day. Plants and animals living in these areas have learned to adapt to these conditions, What types of plants grow in your neighbourhood? Identify any five plants. А. B. By observing the plants, identify any two adaptations shown by the plants that allow the plant to survive in your neighbourhood. C. Suppose there is a park in your neighbourhood. The park is a habitat to a variety of plants, and it is going to be destroyed to build a shopping mall. How would you feel? What can you do to save the park, and thus save the habitat of so many plants? Write down a few steps you would take to save the park.

Answer:
Antarctica is the coldest place on Earth. The temperature in the winter is cold enough to freeze water all the time. The temperature in the middle of Antarctica is much colder than the temperature on the coasts.
Antarctica has two seasons: summer and winter. Earth is tilted in space and the direction of tilt never changes. During summer, Antarctica is on the side of Earth tilted toward the sun. It is always sunny. In winter, Antarctica is on the side of Earth tilted away from the sun. Then, the continent is always dark.
Antarctica is a desert. It does not rain
Explanation:
When most people imagine Antarctica they think of a cold continent covered in ice. And they’re right. In fact, 90% of the world’s freshwater is locked up in Antarctica’s permanent ice sheet. By contrast, the idea of the desert usually conjures images of rippled sand dunes and the shimmering heat of the Sahara. So how is it possible that a cold, ice-covered continent like Antarctica is a desert?
Why is Antarctica a desert?
A desert is defined by the amount of precipitation (rain, snow, mist and fog) in an area. A region that receives very little precipitation (the exact amount depends on who you ask) is classified as a desert. There are many types of deserts, including subtropical, coastal and polar deserts. What they all have in common is a barren, windswept landscape, which makes it difficult for plants and animals alike to gain a foothold on land. This all certainly applies to Antarctica.
The average yearly rainfall at the South Pole over the past 30 years was a tiny 10 mm (0.4 in). Most of the continent is covered by ice fields carved by the wind, and craggy mountains covered in glaciers. While Antarctica is home to wonderful forests of low-lying mosses and lichens, there are only two flowering plants that can survive the harsh conditions. And most of the animals we encounter – penguins, seals, whales and seabirds – rely on seafood for sustenance.
Is there a desert in Antarctica, or is Antarctica a desert?
While most deserts only cover part of a continent, the Antarctic Polar Desert spans the whole of Antarctica. It snows and rains on the coastal Antarctic Peninsula, but in the McMurdo Dry Valleys in East Antarctica, it never rains. In fact, scientists believe that in some parts of the Dry Valleys it hasn’t snowed or rained for 14 million years! So although the coast sees some precipitation, the average across the continent is low enough to classify all of Antarctica as a polar desert.
