<span>Selection (a) is the best answer. Rainforests, through their ecosystems, are able to mitigate the effects of prolonged rain events and droughts that could take place in the areas in which they reside. The expansive canopies and tall trees hold in the moisture that does fall to make sure that the areas within them receive sufficient moisture for growth.</span>
The reason why the lithospheric plates that compose the Earth's crust are constantly moving is A. The underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates.
<h3>Why do plates move?</h3>
The earth's crust is made up of lithospheric plates that rest on the mantle which is molten as a result of the high temperatures of the core.
Convection currents in the mantle result in the plates moving as the currents come up from the core to heat up the mantle.
In conclusion, option A is correct.
