EARTH WEEK

Global warming:Global warming is the increase in the average temperature of Earth's near surface air and oceans.

Climate Control:Climate refers to the overall weather of a location over a long period of time. Climate and climate change is determined by many things including distance from the equator, closeness to an ocean or major body of water, and geographical conditions such as mountains, plains and forests. There are 12 distinct types of climates on our planet, ranging from tropical to polar.


Air Pollution:Air pollution contamination of the air by noxious gases and minute particles of solid and liquid matter particulates in concentrations that endanger health. The major sources of air pollution are transportation engines, power and heat generation, industrial processes, and the burning of solid waste.

Ground Pollution:Ground water pollution, stratum contamination, and ground air pollution are all types of ground pollution. It is the consequence of noxious industrial wastes being dumped. The ground is soaked with them, and contamination is accumulated little by little. As a result, plants begin to die. Then, creatures die too. If the ground is polluted, man will not be able to live either.

Water Pollution:Water conservation refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation.
