Summer

The Earth is divided into two halves – the Northern Hemisphere and the Southern Hemisphere. As the Earth revolves around the Sun, sunlight hits one hemisphere more directly than the other. This causes us to experience seasons. In June, for example, the Northern Hemisphere is tilted toward the Sun and is in summer. The Southern Hemisphere is tilted away from the Sun and is in winter.
