The Atmosphere: the Magnetosphere

The video explains the phenomenon of the northern lights, also known as aurora borealis. It describes how the Earth's magnetosphere interacts with solar wind, trapping ions that lead to the formation of auroras. The Van Allen radiation belt and the ionosphere play crucial roles in this process, resulting in the spectacular light displays seen in the sky.

What are the colorful lights in the sky commonly known as?

• Equatorial lights

• Aurora borealis

• Polar lights

• Southern lights

What role does the magnetosphere play in the formation of auroras?

• It traps ions from the solar wind

• It reflects sunlight

• It generates heat

• It absorbs sound waves

How does the Earth act in relation to its magnetic field?

• As a non-magnetic object

• As a weak magnet

• As a giant magnet

• As a small magnet

What is the Van Allen radiation belt?

• A belt of water around the Earth

• A belt of charged particles surrounding the Earth

• A belt of air currents

• A belt of sound waves

What happens when ions from the sun interact with particles in the ionosphere?

• They create sound

• They form clouds

• They produce heat

• They emit light
