Why is there more daylight during the summer than in the winter?

• The speed of Earth's orbit increases during the summer, causing longer days and shorter nights.

• The Earth's axis is tilted, resulting in longer days in the summer and shorter days in the winter.

• The Earth's atmosphere becomes thinner in the summer, allowing more sunlight to reach the surface.

• The curved surface of Earth causes sunlight to be spread out more during the summer.
