Orbit
Transition of each seasons
Solstice and equinox

The orbital position and changing insolation
During this time the sun reaches its highest noon altitude and stacks reversing its movement towards lower altitude

Less sunlight
Summer solstice in the northern hemisphere
More sunlight
Earth experiences equal lengths of days and nights
