TRUE or FALSE for the statements related to space weather.

"Space weather is the phenomena that occur on the surface of the Sun"

• TRUE

• FALSE

TRUE or FALSE for the statements related to space weather.

"Space weather is the phenomena that occur in space"

• TRUE

• FALSE

TRUE or FALSE for the statements related to space weather.

"Space weather data allow us to determine the Sun’s temperature."

• TRUE

• FALSE

How is the magnetosphere formed?

• It is formed from the interaction of stars and the

  Sun

• It is formed by the interaction between the

  magnetic field brought by the solar wind and

  Earth’s magnetic field

• It is formed when helium reacts with hydrogen

• It is formed when the sunspots become numerous

  on the Sun’s surface

How is the magnetosphere important to the living

things on Earth?

• It helps humans to forecast the weather

• It helps to prevent soil erosion

• It prevents formation of sunspots

• It reduces the pressure exerted by the solar wind

  on Earth’s atmosphere
