Space Weather and Its Effects starts at 10 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Space Weather and Its Effects.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A satellite in low Earth orbit experiences increased drag during geomagnetic storms. Explain why this happens.
A solar storm increases the flux of energetic particles in the magnetosphere. What is one possible effect on satellites?
Describe how a coronal mass ejection (CME) can affect Earth's magnetosphere.
Describe one method used to protect power grids from the effects of geomagnetic storms.
Describe one way in which space weather can impact satellite operations.
