How does Earth's axial tilt cause seasons?

Answer 1

The earth's axis is responsible for the seasons because (for example) we have winter because of the tilt because we are facing away from the sun, in the summer fully towards it, and for spring/autumn we are partially turned towards it.

Answer 2

The tilt and the spin of the earth combined with the sun causes the seasons. Winter=tilting away from the sun

Spring= parallel to the sun

Summer= tilting toward the sun

Fall= same as spring

Due to the position in orbit, as summer solstice approaches your hemisphere is exposed to the sun for longer periods of time each day and at it's maximum is at a much more perpendicular angle causing greater intensity of light at the surface. At the winter solstice and the opposite side of orbit, your hemisphere is then pointed away from the sun and receives much less radiation and much shorter days. At different points in orbit different types of weather are more likely, such as rain in the spring. Vegetation and animal life have adapted to the seasonal changes. Different cultures had different seasons but they were all interpretations of the changes in weather and ecology.
