Question

1. how does the earths magnetism protect life on earth?

it prevents people from floating off into space
it allows the earth to have an atmosphere so we can breathe
it protects the earth from dangerous charged particles from the sun
it burns up meteors to prevent them from hitting the earths surface
it helps to maintain a temperature that is good for life to occur

Explanation:

• The first option is incorrect because gravity, not Earth's magnetism, prevents people from floating off into space.
• The second option is incorrect as the presence of Earth's atmosphere is mainly due to gravity and the planet's mass, not magnetism.
• The third option is correct. Earth's magnetic field (magnetism) deflects dangerous charged particles (solar wind) from the Sun, protecting life from harmful radiation and particle bombardment.
• The fourth option is incorrect because meteors are burned up in the atmosphere (due to friction), not by Earth's magnetism.
• The fifth option is incorrect as Earth's temperature suitable for life is maintained by factors like the greenhouse effect, distance from the Sun, and the atmosphere, not magnetism.

Answer:

C. it protects the Earth from dangerous charged particles from the sun
