At a point on the earth’s surface the angle of dip, . At a point on the earth’s surface, the angle of dip, . We can interpret that:
Options
- A and are both located in the northern hemisphere.
- B is located in the southern hemisphere and is located in the northern hemisphere.
- C is located in the northern hemisphere and is located in the southern hemisphere.
- D and are both located in the southern hemisphere.
Correct answer
C. is located in the northern hemisphere and is located in the southern hemisphere.
Step-by-step solution
As we know that the angle of dip is the angle between earth's resultant magnetic field from horizontal.
At the equator, dip is zero. At Northern Hemisphere, dip is positive. At Southern Hemisphere, dip is negative.
Since, the field lines originate from the South Pole, the angle of dip is negative in Southern Hemisphere. Similarly, as the field lines terminate at the North Pole, the angle of dip is positive in Northern Hemisphere.
