Explain how the tilt of the Earth affects the number of daylight hours a region receives throughout the year.

The tilt causes the number of daylight hours in a region to change as the year goes by, with more hours in summer and fewer in winter.

Why isn't the North Pole the hottest place on Earth during the Northern Hemisphere's summer, even though it receives 24 hours of daylight?

The sunlight is spread out and delivers less energy than a place further south, where the sun is higher in the sky because it’s more tilted toward the Sun.

Key concepts

3 concepts

1
Seasonal change with four distinct seasons only happens in two regions on the planet, and the seasons are reversed.
2
The Earth spins on an axis that's tilted 23.5 degrees from vertical, which is one of the main reasons for the seasons.
3
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.

Practice

5 questions

According to the video, what are the two regions on Earth that experience four distinct seasons?

The video mentions that the Earth is closer to the sun in January than in July. How does the video use this information to disprove a common misconception about seasons?

Quick comprehension check

“Imagine you have a graph showing the number of daylight hours each day in a year. Describe what the graph would look like during the summer months (June, July, August) and the winter months (December, January, February).”
