Curvature Of The Earth
You Have Already Studied impact of the spherical shape of the earth and how this causes distribution of heat over the earth's surface differently , how the region around the equator becomes warmer than those near the poles
Earth's Rotation On It's Axis
The Earth Rotates Or Goes around just like a top spins, What does it go around? It actually rotates around an imaginary line which joins the North pole and the South pole. This line is called the axis of the earth's rotation. All parts of the earth go around this line once a day. In other words,the earth takes about 24 hours to rotate or go around its own axis. It moves from the west to the east if a globe is facing you it rotates from your left to the right side. You can see that the western portion moves towards the east. Take a globe and focus a torch light on it from a small distance. The torch illuminates one half of the globe. If you rotate the globe in front of the light, then also only half the circumference of the globe is illuminated
