how do seasons change
If the path of the earth around the sun doesnât have any affect on the seasons, what causes seasons? As the earth revolves around the sun, it also spins around its axis, which is tilted at an angle of 23.5 degrees. It is this tilt in the earthâs axis that is responsible for creating seasons in the hemispheres. Around the June Solstice, the Northern Hemisphere is titled towards the sun, therefore experiencing summer. The Southern Hemisphere on the other hand, is tilted away from the sun and thus, experiences winter.
