Chapter 9 : Earth's Magnetosphere and it's Importance

Earth's magnetic field line and Earth's magnetosphere line are fixed and does not change.

• True

• False

Pattern of magnetic line in magnetosphere changes a lot.

• True

• False

How is the magnetosphere formed?

• It is formed from the interaction of stars and the Sun

• Interaction of magnetic field line by solar wind and Earth's magnetic field

• Interaction of magnetic field line by solar wind and Earth's atmosphere

• When the sunspots become numerous on the Sun's surface

How is the magnetosphere important to living things on Earth?

• It helps humans to forecast the weather

• It helps to prevent soil erosion

• It prevents formation of sunspot

• It reduces the pressure exorted by the solar wind on Earth's atmosphere

Earth's magnetosphere is defined as a region in outer space surrounding Earth.

• True

• False

Solar Wind colour

• Blue

• Red

• Yellow

• Green

Magnetosphere colour

• Blue

• Red

• Yellow

• Green

Other planets doesn't have Magnetic field

• True

• False

The Magnetosphere cannot reduce the pressure exerted by solar wind on Earth's atmosphere

• True

• False

Charged particles such as electrons, protons and alpha particles in the solar wind are harmful, so the magnetosphere protect Earth from the particles.

• True

• False
