Earth needs no introduction. From its origin to its inevitable future, the story of Earth is greatest story ever told. Get started with this list of 100 Earth facts.
The thermosphere is the thickest atmospheric layer (80-550 km). It’s known for its aurora borealis, orbiting satellites and the Karman Line (edge of space).
Eutrophication occurs in water bodies when too many nutrients are introduced. Over-fertilization of water causes algae to grow blocking sunlight for plants.
All planets have layers. Inside Earth, we have a crust, core and mantle. Imagine a team of drillers who set out to drill a hole to the other side of Earth.
As the Earth spins, the sun always shines on one side which gives it sunlight. When you’re facing the sun, it’s daytime. But when you’re not, it’s night.
Their difference is location. Meteoroids are up in the sky. Meteors fall to Earth and flash light breaking down in the atmosphere. Meteorites are on Earth.
