Scientists, geologists and spiritual faiths advance separate versions of theory of origin of the planet. Whichever theory is true, it is irrefutable that our earth has undergone a tremendous change physically and environmentally. Men have evolved to a great degree to be able to control or in most cases to adapt to the natural forces. With the cognitive prowess men are gifted with, they have overcome the difficulties nature has imposed on them and in the process have mastered techniques to manage them. Men have landed on the moon, explored the deepest ocean floor, fly in the air, travel as fast as the speed of sound, communicate through any measure of distance and accomplished many other things that defy the natural limitations.
Earth is the third planet from the Sun and the fifth largest.
The Atlantic Ocean, Pacific Ocean, Indian Ocean and the Arctic Ocean constitute a major body of water. Liquid water is, of course, essential for life as we know it. The heat capacity of the oceans is also very important in keeping the Earth's temperature relatively stable. Liquid water is also responsible for most of the erosion and weathering of the Earth's continents, a process unique in the solar system today. The tiny amount of carbon dioxide resident in the atmosphere at any time is extremely important to the maintenance of the Earth's surface temperature via the greenhouse effect.
