D. It draws more oxygen into the atmosphere

Answer 1

How does the magnetic field surrounding Earth benefit humankind?

Answer: it prevents the Earth from ultraviolet radiation and other harmful substances from space!

So the answer is C

Answer 2

Option C) It protects us from radioactive particles.

• We are shielded from cosmic rays by the atmosphere and magnetic field of the Earth. We are shielded from cosmic radiation by the Earth's magnetic field, which is highest near the equator and lowest towards the poles. Most of the radiation is deflected away from the earth by the magnetic shield.
• Until the fallout cloud has cleared, keep your mouth and nose covered with a face mask or another item (such a scarf or handkerchief). Seal windows and doors and turn off ventilation systems until the fallout cloud has dissipated.
• A portion of the sun's radiation is absorbed by the ozone layer in the stratosphere, keeping it from reaching the planet's surface. Most significantly, it absorbs UVB radiation, which is a type of UV light. UVB, a type of ultraviolet light produced by the sun and sunlamps, has a number of negative effects.
• In addition to providing us with the oxygen we need to survive, it shields us from dangerous UV solar radiation. Without it, the pressure needed for liquid water to exist on the surface of our planet would not be possible. Additionally, it warms our planet and maintains Earth's habitable range.
