Answer:
There are 54 countries in Africa, today.
Explanation:
The statement underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates explains the movement of these lithospheric plates.
<h3>What is tectonic plate movement? </h3>
The theory discusses how Earth's surface is composed out of rigid slabs of <em>rock</em> that are known as plates. These <u>large pieces </u>of plates under the Earth's surface are regarded as the lithosphere.
Therefore, convection currents that appear in the mantle lead to movements in the plates due to the flow of current to heat up the mantle.

Answer:
Actually the radiation belts are a negative side effect of the earths magnetic field as well as the Suns magnetic field. As cosmic particles collide with particles in the atmosphere they decay into energetic protons while the outer belt is mostly electrons made in geomagnetic storms.
if it didn't exist we could launch more satellites or have larger space stations without the worry of perpetual radiation exposure as for earth there would be no negative consequences to the loss of the energy.
