Earth's magnetic field results from movements in the

a. mantle.

b. outer core.

c. inner core.

d. crust.

Correct answer choice is:

B. Outer core

Explanation:

The Earth's magnetic field diverts most of the solar radiation, whose charged particles can gradually reduce the ozonosphere that protects the planet from harmful actinic radiation. California Institute of Technology reported that the Earth's liquid core is the primary source of magnetic field and it happens from the movement of molten iron and nickel in its liquid outer core.

Earth's magnetic field results from movements in the outer core. Due to the extensive heat at the center of the earth, the outer core is liquid. Earth's magnetic field is created because of the movement of the outer core around the inner core.
