There are many factors that make our planet different from the rest but the most significant one, being that it is the one that keeps us alive, is our atmosphere. Our atmosphere is composed of certain elements and is divided into several layers.

The way our atmosphere was created is a unique story. When our Earth first formed, our planet came its own atmosphere. Scientist believed that the original atmosphere consisted of mainly of Helium (He) and Hydrogen (H). These were the first gasses on this planet but did not stay long. Scientist believe that these gases escaped Earth’s gravitational pull because of how light and fast they were moving. Earth was still a molten rock cooling down, but the temperatures this planet was at caused the light elements to move really fast and float off into space.
