Item WC034002: It is colder in the winter at a given place than in the summer because sunlight reaches that place at a smaller angle in the winter.
A student lives in a town where the summers are very warm and the winters are very cold. Why is it colder in the winter than in the summer?
- Because sunlight is cooled by the cold air in the winter.
- Because sunlight reaches the town at a smaller angle in the winter.
- Because sunlight has to pass through more clouds to get to the town in the winter.
- Because sunlight has to travel a much longer distance to get to the town in the winter.

- NRC Framework
- ESS1.B …the intensity of sunlight falling on a given location on the planet’s surface changes as it orbits around the sun. Earth’s spin axis is tilted relative to the plane of its orbit, and the seasons are a result of that tilt.
