Even though you don't specify it, I believe you are talking about ancient Egypt, since a high percentage of the population of ancient Egypt were farmers, and when they were not farming they were doing other jobs. Specifically during the flood season they were not able to farm so it was then when they worked for the pharaoh on building projects.
I'm pretty sure that the answer to this one is going to be C.
Answer: Subduction zone - The zone in the Earth's crust where the lithospheric plate with the oceanic crust, rolling under another continental crust plate, is called subduction.
Explanation:
Earthquakes fall into three categories, namely shallow, medium and deep. Deep earthquakes occur at depths of 300 to 730 kilometers below the Earth's crust, which are the locations of the hypocenter in the so-called subduction.At the time of an earthquake, Earth's energy is released. It is constantly released, but until the earthquake, it recedes at the moment when rock, rock and earth's crust burst due to overvoltage.
Magma is a species a rock that has a much lower density than the others, so this is the cause of its penetration towards the surface. There are many molten masses in the ground and the most striking example is magma, which exits on the surface in the form of lava. If magma does not have any obstacle to the surface, it will appear in the form of lava.
