The Reasons For The Seasons

The Earth's Tilt

The earth spins around an imaginary axis. A planet's axis is an imaginary line that goes through the North and South poles of the planet. It takes the Earth 24 hours to spin around once on its axis. We call this a day. The Earth's axis is tilted at 23.5 degrees. If the axis wasn't tilted, we would only have one season. Parts of the planet would receive the same amount of sunlight every day, so weather and climate would not change very much. Because the Earth's axis is tilted, we have different seasons. As the Earth orbits around the Sun, the axis sometimes points toward the Sun and sometimes away from the Sun. When this happens, there are times when the Northern Hemisphere is receiving more light than the Southern Hemisphere. The Northern Hemisphere would be having spring or summer, while the Southern Hemisphere would be having fall or winter.

1. Why is the tilt of the earth the cause for seasons on our planet?

2. The North Pole and South Pole each have long periods of complete sunlight and complete darkness. Why?
