500
Which diagram shows the tilt?
See board.

Why is direct sunlight warmer than indirect sunlight?
With indirect sunlight, the rays are dispersed over a larger area. In direct sunlight, the rays are more concentrated on a single area.
500
What direction does the Earth go around the sun? Clockwise or counterclockwise?
counterclockwise
500
On which two days does the Northern Hemisphere receive an equal amount of night and daylight?
Vernal Equinox and Autumnal Equinox
500
Why do we receive more daylight at some times of the year than at others?
When the earth is tilted towards the sun, we receive more direct sunlight for a longer amount of time each day. In the winter, we are tilted away from the sun, and receive indirect sunlight at a low angle in the sky.
