Interesting Facts About Earth
Earth is an extraordinary place, filled with a vast array of diverse and amazing creatures, landscapes, and climates. It is the only planet known to have life and is the only place in the known universe where humans can live. Earth is the third planet from the sun and is the fifth largest in our solar system. It is approximately 4.5 billion years old and is composed of several different layers, including the hydrosphere, lithosphere, atmosphere, and biosphere. Earth has an average temperature of 57°F and contains 71% of its surface covered by water. Its atmosphere is mostly composed of nitrogen and oxygen, with trace amounts of other gases such as argon and carbon dioxide. Earth is home to millions of species, from the smallest microbe to the largest mammal. Here are some interesting facts about Earth that will leave you in wonder and awe.
