Question

Why are summer days longer than winter days on earth?

Answer 1

The sun is father away during the winter.

Step-by-step explanation:

In the northern hemisphere, during the winter it is summer in the southern hemisphere. The sun is farther away for us so the days get shorter in the winter since the sun inches away faster.

Answer 2

Tilt of the Earth

Step-by-step explanation:

The Earth's rotational axis is titled at an angle 23.4°. When then northern hemisphere is pointed towards the Sun it is summer in the northern hemisphere and winter in the southern hemisphere.

In the northern hemisphere a day would be longer and gets more sunlight than the southern hemisphere.

The same happens when it is summer in the southern hemisphere.
