Learn about the Sun

Summer solstice, that falls on June 21, is considered the longest day of the year because it has the most daylight hours between sunrise and sunset. In the summer, the North Pole tilts toward the sun, so the Northern Hemisphere gets more sunlight. On the solstice, the North Pole is tilted the closest to the Sun. On this day, the sun reaches its highest point in the sky.
There’s a lot to learn about our nearest star, the Sun, which may seem calm and steady but is always changing. Its energy causes weather and seasons. The sun provides heat for oceans, air and land. It creates water vapour by evaporating water from lakes and oceans, which drops as rain or snow. And plants and animals can’t survive without light and water.
