The geographical north pole of earth is actually approximately the magnetic south pole of it.

Define magnetic declination. How does it depend on latitudes?

Write the quadrants in which the following points lie:

$\left(-4,7\right)$

5.4 kwh = ?

Consider the following:

1. Electromagnetic radiation.
2. Geothermal energy.
3. Gravitational force.
4. Plate movements.
5. Rotation of the earth.
6. Revolution of the earth.

Which of the above are responsible for bringing dynamic changes on the surface of the earth?

Assertion: The magnetic poles of earth do not coincide with the geographic poles.

Reason: The discrepancy between the orientation of a compass and true north-south direction is known as magnetic declination.
