In the picture on the right, you can see that the Earth "tilts" towards the Sun by around 23°. This is called the Axial Tilt of the Earth. The "poles" sticking out of top and bottom of the Earth are not real of course; they are just there to show you the axis points around which the Earth spins - known as the North and South Poles.
