🌍Earth formed 4.5 billion years ago from particles left over from the creation of the sun.
💦Earth is the only known place with liquid water on the surface, enabling the existence of diverse life forms.
🌱Earth is home to an estimated 1.5 million species of plants, animals, bacteria, fungi, and more.
🔍There are potentially millions, if not billions, of undiscovered species on Earth.
🌎Earth's biodiversity is the result of billions of years of evolution and adaptation in its seas, lands, and skies.
How old is Earth?
—Earth is approximately 4.5 billion years old, formed from particles left over from the creation of the sun.
Why is Earth the only known place with liquid water?
—Earth's unique distance from the sun allows it to maintain liquid water on its surface, unlike other planets.
How many species exist on Earth?
—An estimated 1.5 million species have been identified on Earth, but there are potentially millions, if not billions, more yet to be discovered.
How did life evolve on Earth?
—Life on Earth evolved from primitive microbial organisms in the oceans, eventually giving rise to a wide range of advanced life forms.
What factors contribute to Earth's biodiversity?
—Earth's biodiversity is the result of billions of years of evolution and adaptation in its seas, lands, and skies.
