Facts About The Earth • The Earth is more than four billion years old. • More than six and a half billion people inhabit The Earth. • The Earth is the biggest of all terrestrial planets. • The diameter of Earth is 7,926 miles. • The circumference measured around the equator is 24,901. • About 30% of Earths surface is covered with land while about 70% is covered with oceans. Facts About The Earths Atmosphere • The Earth’s Atmosphere is 77% nitrogen,21% oxygen that has trace’s of carbon dioxide and water. • The Earths Atmosphere water recourse's ecosystems and human communities are effected. • The Earths tempeature,weather,atmosphere and many other factor’s are just right to keep us alive. • The Atmosphere becomes thinner until it gradually reach's space. It is divided into five layers. • Most of the weather and clouds are found in the five layer’s. More Facts About The Earth • The Earth was made with tiny rocks to create the birth of The Earth. • The Earth is the only planet known to have life,land,water,air and sun so human beings can live on The Earth . • Earth is the only planet whose English name does not derive from Greek/Roman mythology. • Special Facts About The Earth • The Earth is the only planet that has water on it’s surface. • The Earth is traveling through space at a speed of almost 18 miles(50 km) per second. • The Earth weigh’s about 6 trillion tons • The Earths first picture of the worlds weather from space was taken in 1960 by the trios 1 satellite. The Rotation Of The Earth • The earth rotates about an imaginary line that passes through the North and South Poles of the planet. • The line is called the axis of rotation. • It takes 1 day to rotate on it’s axis and that’s what cause’s day and night. • Earth travels about 1 / 365 of the way around the sun during one day • There is a small difference between solar time and sidereal time. • It takes The Earth 1 year to revolve around the sun. • The Axis Of Rotation cause’s the season’s. Did You Know… • Every 4 years, we have 1 extra day on February 29.This is called a leap year. • There are millions of other galaxy's in the universe. • If The Earth were as big as Jupiter, it would fill the Earthrise image. • Volcanoes, Earthquakes and heat from inside The Earth make’s it move. • There is enough gold dissolved in sea water to give each person on the planet about 2 pounds. Facts About The Earths Moon • The Earths moon’s name is Luna. • Luna is a beautiful world that lies some 384,400 kilometers from The Earth. • The Moon takes about 27 days (27 days, 7 hours, 43 minutes, 11.6 seconds) to go all the way around The Earth and return to it’s starting position. • The Moon is 4.5 billion years old. • Looking down from the north pole we would see the Moon orbiting counterclockwise from west to east. • The Moon is about 250,000 miles from The Earth. • The moon orbits Earth at an average speed of 2,288 miles per hour. The Earths Stars • All stars were made from clouds of cold molecular hydrogen that gravitationally collapse. • If you could collect all the stars together and put them in piles, the biggest pile, by far, would be the red dwarfs. • The Red Dwarfs are stars with less than 50% the mass of the Sun. • Some stars come in many pairs. • there are 200-400 billion stars in our galaxy. • The closest star to Earth is Proxima Centauri, located 4.2 light-years away. Facts About Fossils • Most fossils are invertebrates. • When an animal or plant dies it is usually completely destroyed when either another animal eats it or when it decays. • Fossils are the naturally preserved remains or trace’s of ancient life that lived in the geologic past. • The kinds of fossils found in rocks of different ages differ because life on Earth has changed through time. • Most fossils are the remains of extinct organisms; that is, they belong to plants or animals that are no longer living anywhere on Earth. • Fossils represent the remains or traces of once-living organisms.
