Rainforests: Earth’s tropical rainforests are home to over half of the planet’s species of plants and animals.
Earth’s Tilted Axis: Earth’s axis is tilted at 23.5 degrees, which is why we experience seasonal changes as it orbits the Sun.
Polar Ice Caps: Earth has two polar ice caps, one in the Arctic (North Pole) and one in the Antarctic (South Pole), which play a key role in regulating global temperature.
