Seasons of Earth

Why do seasons change?

• The Sun is directed to the Southern hemisphere only.

• The Sun is somehow tilted to both Northern and Southern hemispheres.

• Seasons change because the Earth is stationary directing its rays to Northern hemisphere always.

• Seasons change because direct rays of the Sun shift from one hemisphere to the other as the Earth revolves around the Sun.

What is the effect if the Earth is tilted?

• When the Earth is tilted towards the Sun, we have night.

• When the Earth is tilted away from the Sun, we have day.

• It changes the angle that the Sun strikes the Earth in different land areas.

• It causes the Earth to be farther away from the Sun at different times of the year.
