Document Summary
7. are roughly 10 km deep and the deepest magma comes from 300 km deep. This is because we have largely prevented the river from flooding. Earth is protected from sun"s harmful rays by the magnetic field. Plus charged particles in the magnetic field cause particles to spiral around field. Northern lights are charged particles that are luminescing. Ancestors used position of sun and compasses to determine directions and latitudes. Birds and some other animals have built in compasses in some part of their brain. Turtles, sharks, and some other fish have this same compass. Take water from sediment and make minerals. Crystals in their body direct them which way is north, up, and down. Magnetic north and south are different than geographical north and south; it"s slightly tilted. Pigeons have iron-bearing platelets in their beaks. During wwi, soldiers used pigeons to send messages. South america and africa and north america and europe fit almost perfectly together.
