> Earth is 7,926 miles (12,756 km) in diameter. Earth's atmosphere is 77 percent nitrogen and 21 percent oxygen, with traces of argon, carbon dioxide, and water. Earth takes 23.93 hours to rotate on its axis. Because it is tilted on its axis, the planet has four seasons during a year, which is 365.26 days.
 * "If the sun were the size of a soccer ball, Earth would be the size of a peppercorn!"
 * The temperature on Earth ranges from -127 degrees Fahrenheit (-88 degrees Celsius) to 136 degrees Fahrenheit (58 degrees Celsius). The coldest recorded temperature was on the continent of Antarctica. The hottest recorded temperatures were on the continent of Africa.
 * Earth is covered with a hard outer layer called the crust. Beneath the oceans, the crust is only 5 miles (8 km) thick. But beneath the continents the crust may be as much as 45 miles (72 km) thick. This crust is broken into huge slabs called plates. The continents are embedded in these plates. Under Earth's crust is the mantle, a layer of hot, melting rocks that moves in currents of its own. The land plates float on currents of the mantle. The movement is so slow--about 2 inches (5 cm) a year--that it barely seems noticeable. However, it is the power of this movement that explains the continuous drifting of continents over millions of years.
 * The oceans of Earth are unique in our solar system. As far as we know now, no other planet has liquid water above ground. Without oceans, our planet would be uninhabitable. The oceans give Earth its blue color when seen from space. Oceans cover about 70 percent of Earth's surface or about 139,400,000 square miles (361,000,000 square kilometers). They contain roughly 97 percent of Earth's water supply. The average temperature of the world's oceans is 39 degrees Fahrenheit (3.9 degrees Celsius). The average depth is 12,230 feet (3,730 meters).
 * The atmosphere of Earth is a mixture of gases, with dry air composed of 78% nitrogen, 21% oxygen, 1% argon, and trace percentages of carbon dioxide and other gases.
 * Earth is actually covered by one body of water. The oceans are all connected, one flowing into the other.
