Answer: Megacities can influence environment and health concerns.
Explanation:
1. The megacities can pollute the environment by causing air, water, and soil pollution due to rapid industrialization in these cities leaking air pollution and chemical discharge in water and soil contaminating them. This way the environment is affected also the human and animals are prone to respiratory and digestive problems and diseases.
2. The megacities are source of noise pollution from different sources producing undesirable sound like vehicle honking, live concerts, and machines from industry and others these can affect the hearing ability of human and animals also can be responsible for hypertension, cardiac arrest, and stress in humans.
3. The megacities are affected by overpopulation which can affect the environment as resources like water, air, minerals will deplete from these cities and this can affect the survivor of human kind who are not able to meet the resource demand.
Wind and Ocean Currents: �Heat Movers�<span>Both air currents and ocean currents move heat. Energy is stored as "latent heat" in the atmosphere. In the surface waters of the ocean it is stored as "sensible heat." Atmospheric and oceanic circulation share the task of<span>heat </span>redistribution on a roughly fifty-fifty basis. Even though transfer of heat by moving water in ocean currents is much less efficient than transfer by moving vapor in wind, the masses involved are much greater in the ocean currents than in the air currents.
