The one and only known home for life, Earth is one of the most interesting planets of the solar system. Life on Earth is extremely diverse; however, relative to Earth's size, all of life is contained within a very thin layer of its surface and lower atmosphere.
Earth formed around 4.54 billion years ago and is the third planet from the Sun. It is the fifth largest planet in the solar system and the largest of the terrestrial planets. It is also the densest of all the planets.
Earth is the only planet in the solar system not named after a Roman or Greek deity. The hottest recorded temperature is 136 degrees Fahrenheit. Scientists believe that Earth once had two moons. The longest mountain range on the planet is underwater and is called the mid-ocean ridge.
Earth's crust is both the outermost and the thinnest of the planet's layers, is composed mostly of oxygen and silicon, and is where the most ancient rock samples in the world have been found. Overall our planet's crust ranges from 3 to 44 miles in thickness, extending to as much as 60 miles deep in
The Earth's crust, which is Earth's outermost layer, is a thin layer. Comprised of two kinds of crusts, continental and oceanic crusts, it is merely 0.473 percent of Earth's mass. The ocean crust's thickness is around 7 km, while the continental crust's thickness is from 10 to 75 km.
The mantle is the largest of the geological layers that make up the Earth. It is found beneath the crust and is about 1,800 miles thick. Surrounding the core, the mantle makes up about 84 percent of the volume of the Earth.
The inner core is the Earth’s deepest layer, and it is a solid iron ball that is approximately 1,500 miles in diameter. Although it is extremely hot, the iron cannot melt due to the high pressure. The inner core also consists of nickel and sulfur and smaller amounts of elements other than iron.
An interesting fact about Earth, Wind & Fire is the band’s name is a reference to the qualities of its founder’s astrological sign. Another interesting fact is the band’s brass horn section, The Phenix Horns, appeared on two Genesis singles and Phil Collins' debut solo album. The band’s founder, Mau
Earth is the only planet that has liquid water on its surface, it is 93 million miles from the sun, and the Atlantic Ocean is the saltiest of the oceans. Earth is a unique planet in the solar system.
An interesting fact about the number 50 is that this number is stated 154 times in the Bible. The first book of the Bible, which is Genesis, contains 50 chapters. Pentecost, also called Shavuot, is a Jewish feast day that occurs 50 days after Passover.
