To provide defense against these sporadic attacks, the early settlers erected a series of forts in the area. Wood's Fort guarded the Forks-of-the-River just downstream from Newport, and McCoy's Fort and Whitson's Fort defended the area to the south.
The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system's mass is in the Sun, with most of the remaining mass contained in Jupiter.
Prior to the inner core's formation, the entire core was molten, and the age of the inner core is thought to lie between 2â4 billion years. Because it is younger than the age of Earth (about 4.5 billion years), the inner core cannot be a primordial feature inherited during the formation of the solar system [citation needed]. Dynamics
