The document summarizes the formation of the Earth over geological time in three sentences: Meteorites continually bombarded the early Earth, allowing the planet to increase in size. The early atmosphere formed without oxygen as the first oceans and continents developed. Over billions of years, microbial life evolved and helped produce an oxygen-rich atmosphere, paving the way for more complex multicellular organisms.

28. • How did the moon get here / form?

29. • Theories on how moon was formed?
– The Fission Theory: The Moon was once part of the Earth and
somehow separated from the Earth early in the history of the
Solar System. The present Pacific Ocean basin is the most
popular site for the part of the Earth from which the Moon
came.
– The Capture Theory: The Moon was formed somewhere else,
and was later captured by the gravitational field of the earth.
– The Condensation Theory: The Moon and the Earth
condensed together from the original nebula that formed the
Solar System.
– The Colliding Planetesimals Theory: The interaction of earth-
orbiting and Sun-orbiting planetesimals (very large chunks of
rocks like asteroids) early in the history of the Solar System
led to their breakup. The Moon condensed from this debris.
– The Ejected Ring Theory: A planetesimal the size of Mars
struck the earth, ejecting large volumes of matter. A disk of
orbiting material was formed, and this matter eventually
condensed to form the Moon in orbit around the earth.
