Earth with millions of fusion reactions every second.

Earth acts like a big magnet due to its components namely, nickel, silicon,
iron and other metallic substances. Inside the earth there is a process called
convection, it is the movement of the metals which has charges; if these
charges move it creates a magnetic field.
The Sun continuously burns with millions of fusion reactions every second.
These reactions are at very high temperature which will transfer to the gasses
surrounding the star and create plasma. In analogy, when a volcano erupts, it
releases tons of ash and pyroclastic materials into the sky and its neighboring
places. The same things happens on the Sun, it blasts plasma into the solar
system and the speed of its particles depends on how active the sun.
Earth’s magnetic field provides a barrier to the solar wind, called the
magnetosphere. The solar wind interacting with the Earth’s magnetic
field transfers some of its energy into the upper atmosphere in the Polar Regions.
The auroras that are visible at high latitudes are one manifestation of this
transfer. But it also heats up atmospheric ions enough that they escape up out
of the poles, forming Earth’s “polar ion outflows”(Schirber, 2011).
In a planet or a moon without a magnetic field, the solar wind will hit it
directly. That’s what happens on the moon. All of the charged particles are
constantly hitting the surface that faces the Sun. If a planet has a magnetic field
like Jupiter and Earth, the solar wind neither will nor hit the planet directly or in
other words it will be deflected.
The planets near to Earth like, Mars and Venus, have no oceans or lakes.
Researchers and experts believe that they were blown dry or get evaporated
by the solar wind. The solar wind basically barrels straight into the upper
atmosphere and scoops up ions and carries them into space. Earth has
escaped this phenomenon because of its strong magnetic field which deflects
the wind.
