Dynamo-like motions in earth's interior
Did you know?
WebThere are three requisites for a dynamo to operate: • An electrically conductive fluid medium • Kinetic energy provided by planetary rotation • An internal energy source to drive convective motions within the fluid.[8] In the case of the Earth, the magnetic field is induced and constantly maintained by the convection of liquid iron in WebTo understand how a dynamo would work in the context of the Earth, we need to understand the physical conditions in the Earth's interior. The Earth is composed of layers: a thin outer crust, a silicate mantle, an outer core and an inner core. Both temperature and pressure increase with depth within the Earth.

The annual motion of the Earth is called revolution. Since the path of the Earth is elliptical, the interval between the Earth and the Sun keeps shifting. The Earth attains four critical positions concerning the Sun. This happens due to the inclination of the Earth along its axis. These are equinoxes and solstices. sims 3 store exchange
