Early predictions have thrown up some rather strange and peculiar thoughts as to what is making up our Earth‚ but now day¡¦s scientists can be confident that the Earth is made up of what they think.

I have been a competitive swimmer for four years‚ and there isn’t one competitive swimmer who hasn’t heard about‚ seen or used a LZR Racer racing suit. Most wouldn’t think a space shuttle and a competitive swimmer have a lot in common‚ but both have to compensate for the forces of pressure and viscous drag‚ the force of friction that causes a moving object to slow when moving through a substance‚ like air or water.

at 4 and it reflects at 2‚900 km. also known as the outer core. Wave B is the P-wave because the velocity starts at 8 and it refracts at 2‚900 km. and it refracts at 5‚100 km. also known as the inner core. The mantle starts at 1‚800 km. because wave A and wave B both refract at that point and the outer core starts at 2‚900 km. because wave A reflects from that point and wave B refracts at that point. So the boundary from the mantle to the outer core 1‚100 km. The boundary of the inner core is 5‚100

a 2003 science-fiction film wherein the world is about to encounter its impending doom because the Earth’s outer core is stalling. It is revealed by a geophysicist that if the liquid outer core stop rotating then the Earth’s electromagnetic field will collapse‚ making the earth vulnerable to disintegration. The only way they can save the Earth was to somehow restart the activity in the outer core. To do so‚ a group of scientists and astronauts were formed. Together‚ they build a ship equipped with

History of the magnetic filed Earth’s magnetic field is a field of electric current that is conducted from the earth’s solid inner core through the liquid outer core (Richard). The electrical current goes around the earth and through it at the north and south poles. The north pole was first discovered by James Ross in 1831 (nasa.gov). No one visited it again until the early 1900s. "In 1904‚ Roald Amundsen
