Earth's Mag. Field

Front

What is Earth's magnetic field?

Back

The magnetic field surrounding Earth, generated by the movement of molten iron in its outer core, which extends into space and protects the planet from solar winds.

Front

What force shields Earth from solar winds?

Back

Magnetic Force.

Front

What creates the magnetic field around the Earth?

Back

The liquid outer core spinning around the solid inner core in combination with the Earth's rotation.

Front

What is the term for the spinning of the Earth on its axis?

Back

Rotation.

Front

What is the difference between rotation and revolution?

Back

Rotation refers to the spinning of Earth on its axis, while revolution refers to Earth's orbit around the Sun.

Front

What are magnetic field lines?

Back

Imaginary lines that represent the direction and strength of a magnetic field, showing how magnetic forces interact.

Front

What happens when two magnets are attracting each other?

Back

Their magnetic field lines point towards each other, indicating a pull between the magnets.

Front

What happens when two magnets are repelling each other?

Back

Their magnetic field lines point away from each other, indicating a push between the magnets.

Front

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

Back

It protects the planet from harmful solar radiation and cosmic rays, and it helps in navigation for animals and humans.

Front

What is the role of the Earth's outer core in generating the magnetic field?

Back

The movement of molten iron in the outer core creates electric currents, which in turn generate the magnetic field.
