Answer:
D. Reversal of Earth's magnetic field
Explanation:
The earth's magnetic field changes over time and this causes changes in the direction of magnetization of magnetic elements or minerals in rocks.
Our magnetic field is widely believed to originate from activities within the outer core where molten iron and nickel moves. The flow of these molten elements results in the production of the magnetic signatures on earth surface.
Some elements and minerals within rocks are capable of recording the direction of magnetic fields at a period in time. Before magma cools, such minerals in these rocks aligns their poles to that of the prevailing direction of the earths magnetic field. This is how the magnetic changes at the mid-oceanic ridges are recorded.
Answer:
The process of seafloor spreading is responsible for "creating magnetic changes" along mid-ocean ridges.
Explanation:
(b) the afriacn plate is spreading apart to form two seperate plates
(c) the eurasian plate is converging with the afriacn plate
(d) the eurasian and aribian plates are diverging
The correct is - (b) the African plate is spreading apart to form two separate plates.
The African tectonic plate, on of the biggest ones, but it will not be like for a long time in the future as the plate is separating into two parts. The eastern part of the plate is moving towards east, and it is moving away from the mainland Africa. Because of this movement, cracks have been forming all over the eastern side of Africa, thus the numerous faults. Over time, as the distance is increasing, the space in between will fill with ocean water, thus making a natural barrier between them, as well as setting the foundations for the creation of a new sea, or maybe even an ocean.

This is the correct answer, on e2020 at least. Hope this helps!
B Roads must be built to get access to the area.
C Minerals need to be sold for profit.
D Trees need to be replanted to reclaim the land.
Answer:
It is A and B
Explanation:
Before you mine, you need to clear the trees near it, becuse it could be obsticles when you are mining.
You might have to build roads if you are using vehicles when you mine and for better transportation
