The climate and weather of Antarctica
<html>
<h3>Yesterday you learned about the difference between &#x27;weather and climate&#x27;. </h3>
<p><strong>There are many places on earth and all has different weather and falls in different &#x27;climatic regions</strong>&#x27;, but lets have a look at one of the coldest places on earth, Antarctica.  </p>
<p>Most of it is covered by ice but because of &#x27;climatic changes&#x27; and &#x27;global warming&#x27;, scientist are very worried about the ice melting and the effect it has on this region and on the animal life.</p>
<ul><li><em>Can you remember what is the meaning of &#x27;global warming?&#x27;  Have a look at the video and write a few sentences on what you know about this.</em></li></ul>

<p><strong>Even though Antarctica is covered by ice, it can still be called a desert</strong>, because it gets such a little bit of rain (which is called &#x27;precipitation&#x27;) and for long times none at all.  </p>
<p>There are also very strong winds blowing here and the average temperature is about -50 degrees Celsius (Brrrr that is colder than your freezer.)</p>
<h3>But why is this such a dry and cold place?</h3>
<ol><li>Some parts of the winter it will be dark for 24 hours at a time, which means not a lot of sunlight reaches Antarctica.</li><li>Because of all the ice, most of the sunlight is reflected (send back) into outer space.</li><li>The cold air cannot hold so much &#x27;water vapor&#x27; (water in gas form) as the hot air, so it does not rain a lot.</li></ol>
<p><strong>Antarctica is covered with ice and at some place the ice can be as thick as 2.5 km </strong>(what?  that is very very thick).  At some places you will see the top of mountains stick out above the &#x27;ice sleet&#x27; and we call it &#x27;Nunataks&#x27;</p>

<h3>We find icebergs in Antarctica - what is an iceberg?</h3>
<p>A glacier (this is like a mountain made of snow that is &#x27;compressed&#x27; and has become hard) moves around and as they move, they will crack and huge holes and &#x27;crevasses&#x27; will form.  Parts of the glacier will fall off and this is then called an iceberg.</p>

<ul><li><em>After you have watched the video, answer the following questions</em></li></ul>
<ol><li><em>What is another name for &#x27;glaciers&#x27;?</em></li><li><em>In which country will you not find glaciers in the mountains?</em></li><li><em>How will a glacier form?</em></li><li><em>Why will the glacier move?</em></li><li><em>Do they move slow or fast?</em></li><li><em>Why can we say that glaciers &#x27;are powerful&#x27;?</em></li><li><em>Name a few ways in which the glaciers can shape the environment.</em></li><li><em>What is &#x27;erosion&#x27;?</em></li></ol>
<p>The &#x27;ozone layer&#x27; that protects us from the harmful rays of the sun is very thin over Antarctica.</p>
<p>We find a few kinds of <strong>animals in Antarctica</strong> like different types of seals and penguins and whales and birds called albatrosses.  These animals have adapted that they can survive in this very cold climate.</p>
<ul><li><em>What does it mean if animals are adapted to the cold climate?</em></li><li><em>Have a look at the beautiful photos of some of the animal life in Antarctica </em><a href="https://www.nationalgeographic.com/animals/photos/antarctic-animals/"><em>https://www.nationalgeographic.com/animals/photos/antarctic-animals/</em></a></li><li><em>Choose one animal that interests you and find extra information on it.</em></li></ul>
