Item CL121002: Changes in the angle between earth’s axis and the sun cause the amount of time that sunlight can reach a place on earth to change over the course of a year.
What causes the number of hours of daylight a place receives to change over the course of a year?
- Changes in the moon’s path around the earth cause the moon to block sunlight from reaching a place for different amounts of time over the course of a year.
- Changes in how fast the earth turns on its axis cause a place to spend different amounts of time in sunlight over the course of a year.
- Changes in the earth’s distance from the sun cause the amount of time that sunlight can reach a place to change over the course of a year.
- Changes in the angle between earth’s axis and the sun cause the amount of time that sunlight can reach a place to change over the course of a year.
