How the tilt of the earth affects the seasons and the length of daylight?
Say for example you live in the northern hemisphere. During the summer months the rays of the sun are pointed almost directly above so the heat from the sun is more concentrated. In the winter months, the Earth is tilted in a different direction and the suns rays are concentrated over a larger area of the Earth so there is not as much heat. This is why it is warmer in the summer and colder in the winter.
As far as the length of daylight is concerned, near the equator the amount of daylight stays pretty much constant throughout the year. In the northern hemisphere daylight is around 15 hours per day during the summer and approximately 9 hours during the winter. This is in direct relation to what direction the Earth is tilted in. When the Earth is tilted in the direction of the sun we have warmer seasons and longer days.
