<h3>
What do you understand by seafloor ?</h3>
The surface of an ocean or sea: seafloor According to this theory, the Earth's crust is divided into a number of enormous plates that together form the continents and ocean floors and are supported by a warm, plastic "mantle" beneath the surface. Mr. Walter Sullivan
Deposits of common minerals like copper, zinc, nickel, gold, silver, and phosphorus can be found on the seafloor. These deposits are nodules on silt from the abyssal plain that are typically 3 to 10 centimeters (1 to 4 inches) in diameter and appear as crusts on volcanic and other rocks.

Hydroelectric energy
Explanation:
In a dam area, the most likely energy resource would be an hydro-electric energy source.
Here the dammed water is used to produce electricity by forcing turbines to rotate.
- Hydroelectric power stations are sited near huge water bodies especially a dam.
- The moving water is used to drive heavy turbines that been designed to move electricity.
- An area with huge amount of water has immense potential to generate hydroelectric power.

Hey there!
Oligarchy is rule by the rich, usually aristocrats. They indeed did not get their money in an honest way. In most oligarchies, they made laws that benefitted themselves, like unfair tax and odd charges. A common outcome of this type of government is making the rich richer and the poor poorer.
Hope this helps!
