Earth's magnetic poles are in the same place as the geographic poles.

• True
• False

Geographic North and magnetic North are...

• opposite.

• the same.

• not related.

• 90 degrees to each other.

What is the main purpose of Earths magnetosphere (magnetic field)?

• To protect Earth from radiation from solar winds.

• To help keep the Earth rotating.

• It creates gravity.

• So that we know what direction we are going when using a magnet.

The South Atlantic Anomaly (SAA) is an irregular "dent" in the Earth's magnetic field. Why is it important for scientists to track this anomaly?

• Satellites that revolve in lower Earth orbit can be damaged by radiation let in by the dent

• The dent can let in radiation that can damage people and animals

• The dent can cause massive storms due to the increase in radiation

• Radiation let in by the dent can interfere with navigation equipment that uses magnets
