Why do we get more Sunlight in the summer than in the Winter?

You might not have noticed this, but the Earth tilts over slightly. If you have a globe at home or in school, you can see that the line between north and south poles that goes through the centre of the Earth is not vertical. It 's actually tilting over by about 23 degrees. In Summer, the North Pole is pointing towards the sun so the sun rises and sets roughly from due east to due west. In winter, the Earth is on the other side of the sun so the North Pole is pointing away from the sun. This means the Sun rises and sets more towards the southeast and southwest. You might notice this as you look out of thw window. Think back to how high in the sky the sun was during summer.
