History of the Earth Starts with the formation of our solar system which began long ago in galaxy far far away The nebular hypothesis The nebular hypothesis suggests how our

solar system was formed What is a nebula? Famous nebulas A nebula is a cloud of dust, hydrogen, helium, and other gases

Nebulas are the birth place of stars Nebular Hypothesis Nebular Hypothesis 1. A nebula begins to spin and condense.

2. In the center, the hydrogen collects and forms a hot, dense ball (protostar). 3. When nuclear fusion begins, the hydrogen atoms fuse and ignite the star. 4. The remaining dust around the star

collects and clumps into planets.
