Earth’s Magnetic Field starts at 8 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Earth’s Magnetic Field.
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 11
Define magnetic inclination (dip).
Describe how the Earth's magnetic field helps in navigation.
Describe the process of magnetic field reversal and its possible effects on Earth.
Explain the difference between the geographic pole and the magnetic pole.
Explain the term 'magnetic meridian'.
Explain why the Earth's magnetic field is not perfectly aligned with its rotational axis.
Explain why the magnetic north pole is actually a south magnetic pole in terms of physics.
If the horizontal component of the Earth's magnetic field at a place is 0.3 Gauss and the angle of dip is 60°, calculate the total intensity of the magnetic field at that place. (Use: Total intensity = Horizontal component / cos(dip angle))
If the magnetic declination at a place is 5° east, what does it mean?
Name the two main components of the Earth's magnetic field at any location.
State one difference between magnetic declination and magnetic inclination.
