What is the purpose of the Earth's magnetic field?

The correct answer is To shield the Earth from solar wind and cosmic radiation. Key Points

• 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 planet's core.
• This creates a magnetic field that extends out into space and protects the planet.

Additional Information

• The Earth's magnetic field does not provide energy for life on Earth.
• While the Earth's magnetic field may have some impact on the climate, its primary purpose is to protect the planet from solar wind and cosmic radiation.
• The tides are primarily caused by the gravitational pull of the moon and the sun.
• The magnetic field that emanates from Earth's interior and interacts with the solar wind,a stream of charged particles that comes from the Sun, is called the geomagnetic field, or Earth's magnetic field.
