Structure of the Earth Structure of the Earth The internal structure of the Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core. Scientific understanding of the internal structure of the Earth is based on observations of topography and bathymetry, observations of rock in outcrop, samples brought to the surface from greater depths by volcanoes or volcanic activity, analysis of the seismic waves that pass through the Earth, measurements of the gravitational and magnetic fields of the Earth, and experiments
Evacuate Earth propose that colonists will eat insects and algae, which are easily replenished and space efficient. The ark ship launches and quickly speeds away, a few days later the neutron star is close enough that its tidal force begins to deform the Earth's core and the crust, which causes massive earthquakes and volcanism. Next, the gravity from the neutron star tears away the surface, causing the crust to shatter and the hot interior of Earth to spill out into the vacuum of space, destroying the Earth, but only the colonists on the ark can witness this event, as the rest of
