Hydrothermal Vents occur along divergent plate boundaries on the ocean floor. Hydrothermal vent systems give off plumes of hot, mineral-laden water with temperatures as high as 350 degrees Celcius. The water is ejected through a spout known as black smokers. Metal-rich minerals precipitate out of the circling sea water and forms ores of copper, zinc and iron.
Answer:
People's Republic of China
1/4 of the world's people live in East Asia, the largest cluster of inhabitants. 5/6 of the people in this concentration live in the People's Republic of China, the world's most populous country. Chinese population is clustered near the Pacific Coast and in several fertile river valleys.
Short Answer:
buoyancy
Long answer:
An object submerged in water displaces water according to how much it weighs. In fact, the water will push upward against the object with a force equal to the weight of the water it displaces. For example, a bowling ball and a beach ball that are the same size will have the same volume. The bowling ball, however, is more massive and thus denser than the beach ball. In both cases, the water pushes up against the ball with a force equal to the weight of water it displaced. In the case of the bowling ball, it weighs more than the amount of water it displaced, so it sinks. The beach ball, however, displaces very little water and the air inside it is much lighter than the weight of the water it displaced, so it floats.When lifting something underwater, you have the help of water pushing the object upwards along with your own strength, which is why it's easier to pick up things underwater than on land.

The answer is powerful Chemical. Powerful chemical like
nuclear power can potentially give accidents, generation
of plutonium, limited uranium supply, cost, radioactive waste. Though
there are also advantages of using nuclear power like 1 kg of enriched nuclear
fuel produces 2 million times the energy in 1 kg of coal.
