How are temperatures throughout the year affected by the angles of sunlight?

Answer:

The greater the angle between the direction of travel of the light from the sun and the surface of the planet at a given altitude, the more 'spread-out' the sun light has to be over a wide area and the lower the temperature of the surface. This is the basis of seasonal temperature changes on Earth.
