Earth equator tropics poles circles [information over pictures] [1]

The Earth is round like a ball [a sphere]. If we cut this sphere in half sideways we create two halves of a sphere. These are called hemispheres.	The Earth has an imaginary line which separates the hemispheres called the Equator. It encircles the Earth.	The top half above the Equator is called the Northern Hemisphere. The bottom half below the Equator is called the Southern Hemisphere.
At the very top of the Northern Hemisphere [looking from above] is the North Pole. This is encircled by another imaginary line called the Arctic Circle.	At the very bottom of the Southern Hemisphere [looking from below] is the South Pole. This is encircled by another imaginary line called the Antarctic Circle.

Look at all of the pictures in turn. As you hover over each one a blue screen appears with an explanation of what the picture shows. Important words are highlighted. If you are certain that you know about the picture click on it and it will disappear. As you go through all of the pictures you will get rid of all those which you know about and be only left with those you may be unsure of. In some cases you may get rid of all of the pictures in which case you are ready to move on to other activities which will test your knowledge on that particular topic.
