Answer:
Explanation:
At constructive margins such the mid oceanic ridge where new magma are brought to the surface, evidences abounds to support the theory of continental drift through paleomaganetism.
Continental drift is simply the moving of the land masses on earth from their original positions.
There are certain magnetic minerals in rocks that are able to record the prevailing magnetic conditions in a particular terrane. In a hot magma, at the oceanic ridge for example, these minerals align to the magnetic direction at work during the period when they are cooling. As new materials upwells, the cool layer shifts away from the margin each bearing the paleomagnetic record.
Therefore, through a series of reversals and normality in the magnetic direction, one can deduce that the continents actually moves.

Answer:
A) sea level drops; land subsides
Explanation:
The sea is the final destination of all streams on land. All streams empty into seas which are the basins that collects all terrestrial materials.
The base level is the lowest level to which a river can erode its channel. The base level is greatly influenced by what happens to a sea.
When a river reaches its base level, erosion ceases. If a river is young and set above its base level, we see a rapid rate of erosion.
A sea, the final basin of depostion of rivers controls the base level to a very large extent. When there is a tectonic movement and a sea subsides. It becomes more deeper and lower. Sea level also falls and materials grades seaward. A river would cut rapidly along its channel and its bed to measure up to the level of the ocean.
Therefore, we see a very rapid rate of erosion of channels when sea level falls and the earth sags downward. This would lead to a lower base level.
When sea level rises and there is a tectonic uplift, rivers erode their channels less and begins to aggrade materials. The base level also rises.
Despite his nature of giving, Musa's massive spending and generous donations created a massive ten year gold recession. In the cities of Cairo, Medina, and Mecca, the sudden influx of gold devalued the metal significantly. Prices of goods and wares became greatly inflated.
I hope his helps!! :))
None of them because this question is worded awfully
