Early Earth

Written by on December 12, 2009 in Learning with 0 Comments

Earth was born 4.56 billion years ago. During its infancy, it suffered through long periods of violent bombardment from enormous asteroids and comets. Its surface, devoid of any water at this time, had been scorched by numerous Volcanoes spewing red hot laval. As a result, a primitive atmosphere of noxious gases formed which enveloped the surface and choked off any possibility to nurture life.

During these early years, Earth was encircled by a belt of debris similar to the rings of Saturn we see today. This ring was the result of a previous catastrophic collision with a large planetary body about the size of Mars. The collision had ejected large quantities of Earth’s outer surface into orbit around the planet. The debris had eventually coalesced to form our Moon which had orbited much closer at that time.
