How does the tilt of Earth's rotation axis affect Earth's weather?

I'm no Eisten, but from what I remember when I was in middle school. The Earth's rotation axis affect Earth's weather for seasons. The seasons change (weather) depending on the amount of sunlight as earth revolves around the sun.

The amount of heat energy received at any location on the globe is a direct effect of Sun angle on climate, as the angle at which sunlight strikes the Earth varies by location, time of day, and season due to the Earth's orbit around the Sun and the Earth's rotation around its tilted axis. Seasonal change in the angle of sunlight, caused by the tilt of the Earth's axis, is the basic mechanism that results in warmer weather in summer than in winter.
