<span>Most of the charged particles from the sun are deflected around earth by the Earth's magnetic field.
Inside the Earth lies molten core. High percentage of the core is iron. This iron rotates around the center and create magnetic field. This field extends out of the Earth into the space. It surrounds Earth and protects it from the charged particles. Those particles are diverted to the magnetic poles and they create lights in the atmosphere by reacting with gases in atmosphere. On the north magnetic pole we can see northern lights (aurora borealis) and on the south magnetic pole we can see south lights (aurora australis).</span>
Limitations are important to understand for placing research findings in context, interpreting the validity of the scientific work, and ascribing a credibility level to the conclusions of published research. This goes beyond listing the magnitude and direction of random and systematic errors and validity problems.
El Niño is a natural event that periodically weakens the
western surface of ocean currents in the equatorial pacific ocean. In an El Niño,
the wind that pushes water around (which keeps the east warm and west cold)
gets weaker making the ocean warmer, changing the air temperature and precipitation patterns in the United States.
the most common land use is for farm land
