Origins & Early Life

Earth is the third planet from the Sun and the only astronomical object known to harbor life. This is made possible by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its ocean, which covers 70.8% of Earth's crust.

Career & Major Achievements

The remaining 29.2% of Earth's crust is dry land, which is predominantly located within Earth's land hemisphere in the form of continental landmasses. Most of Earth's land is at least somewhat humid and covered by vegetation, while large ice sheets at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers, and atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes.

Enduring Legacy & Impact

Earth has a liquid outer core that generates a magnetosphere capable of deflecting most of the destructive solar winds and cosmic radiation. Earth has a dynamic atmosphere, which sustains Earth's surface conditions and protects it from most meteoroids and ultraviolet light at entry. It is composed primarily of nitrogen and oxygen.

Notable Quotes by Earth

“The Earth is the only place in the universe we know of that can support life.” (1977)

Historical Fact-Check Quiz: Earth

True or False: “Myth: Earth's entire surface was once covered by a single, global ocean, and no continental landmasses ever existed.”

Answer (FALSE ❌): This is a myth. While Earth did have early oceans, the existence of distinct, interacting continental landmasses, such as those forming the supercontinents, is a documented geological reality.
