GEOLOGY

Detailed explanation-1: -Generated by the motion of molten iron in Earth’s core, the magnetic field protects our planet from cosmic radiation and from the charged particles emitted by our Sun.

Detailed explanation-2: -The Magnetosphere Protects Earth’s Atmosphere The magnetosphere deflects much of the solar particles and energy that stream towards Earth at all times. Without the magnetosphere, Earth’s layered atmosphere would deteriorate due to the constant bombardment of solar wind.

Detailed explanation-3: -She explains in more detail how the solar wind disrupts our magnetosphere: “As the wind flows toward Earth, it carries with it the Sun’s magnetic field. It moves very fast, then smacks right into Earth’s magnetic field. The blow causes a shock to our magnetic protection, which can result in turbulence.”

Detailed explanation-4: -We know much about the solar wind at the orbit of the Earth. It flows with a speed of about 400 km s"1 and has a density of about 5 electrons and ions cm"3. It carries a magnetic field of about 5 nT, lies on average near the ecliptic plane in an Archimedean spiral pattern, but is highly variable about this direction.
