Daylight Hours and Seasons
Learning Objective
I can interpret a graph of daylight hours to describe seasonal patterns.
Key Concepts
Seasonal change with four distinct seasons only happens in two regions on the planet, and the seasons are reversed.
The Earth spins on an axis that's tilted 23.5 degrees from vertical, which is one of the main reasons for the seasons.
The amount of solar energy an area receives changes based on how high the sun is in the sky, which changes during the day between sunrise and sunset.
