The diagram shows planet Earth during the Northern Hemisphere’s summer. What causes the difference in hours of sunlight during the summer at these types of locations?

• Because of the tilt of our Earth, the Northern Hemisphere receives more hours of sunlight during the summer, and the Southern Hemisphere receives less.

• The sun is higher than Earth in its orbit during the summer, causing the Northern Hemisphere to get more sunlight.

• The sun is not large enough to light two places on Earth at once, so some locations receive more sunlight than others.

• Locations 66° north of the equator are always closer to the sun during the day.
