Essay on life underwater
Answers
Answer:
Explanation:
The realm below the surface of the water where the water remains in a natural state like in oceans, ponds, lakes etc. form the underwater. Almost three-quarters of the surface of the Earth is covered by water. Humans are engaged in a number of activities conducted underwater like scuba diving, research etc. But however, almost a majority of the underwater still remains unexplored and is expected to have several million undiscovered species of flora and fauna.
Man cannot survive underwater because there is too much pressure at that level which makes breathing extremely difficult. The density of water also causes many difficulties at that level. As the underwater depth increases, the visible light starts diminishing. The colour spectrum is speedily altered with increase in depth. In greater depths underwater, the temperature remains very low because of minimal heat energy reaching that level. Sound also travels almost four times faster in that level.
