Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Magnetic field?Geodynamo simulation, space weather prediction, paleomagnetism
2. What is the geodynamo source?Convective motion of electrically conductive fluid in the outer core
3. What is the radiation belts?Van Allen belts trap energetic particles
4. What is Earth's magnetic field?It is a giant invisible bubble made by moving liquid iron and nickel in Earth's outer core that protects us from space.
5. How does Earth's magnetic field protect us from the Sun?It deflects most charged particles from the solar wind, keeping them from hitting our atmosphere and surface.

Geodynamo: The process generating Earth's magnetic field through the motion of conductive fluid in the outer core.
Magnetosphere: The region of space dominated by Earth's magnetic field, deflecting solar wind.
Solar Wind: A plasma stream of charged particles emanating from the Sun, interacting with the magnetosphere.
Paleomagnetism: The study of Earth's past magnetic field as recorded in rocks.
