Q: What is the purpose of the Earth’s magnetic field?
  • A. To generate tides in the sea
  • B. Providing an energy source for life on Earth
  • C. Protecting the Earth from solar wind and cosmic radiation
  • D. Controlling the earth’s climate
Correct Answer: Option C - The purpose of the Earth’s magnetic field is to shield the planet from solar wind and cosmic radiation. This is important because these particles can be harmful to life on Earth and can cause damage to our atmosphere. The Earth’s magnetic field is generated by the movement of molten iron in the earth’s core. This creates a magnetic field that extends out into space and protects the planet.
