Exam 4: Formation of the Solar System and Other Planetary Systems

For the first 400 million years or so after the formation of the solar system,the rate of bombardment by large objects decreased.Then,from about 400 million to 700 million yaers after the formation,this rate increased again.What is believed to be the cause of this increase,the period of Late Heavy Bombardment?
