TORNADO :defined as a violently rotating column of air extending from a thunderstorm to the ground – are often formed when warm and cold air masses clash. They are capable of tremendous destruction.
ACID RAIN: is a result of air pollution.Power stations,factories and cars all burn fuels and therefore they all produce polluting gases. Some of these gases react with the tiny droplets of water in clouds to form acids which then falls as rain.
ENVIRONMETAL POLLUTION:is the introduction of harmful pollutants into a certain environment that make an environment unhealthy to live in. The pollutants are usually chemicals, garbage, and wastewater.Environmental pollution is causing massive damage to the ecosystem that organisms depend upon the health of this environment to live in.
STUNAMI:is a series of huge waves that strike a coast. The waves are caused when massive amounts of water are displaced due to an undersea disturbance. Earthquakes, Volcanic Eruptions,Meteorites or even nuclear weapons testing can cause them.
EARTHQUAKE: are the rumblings, shaking or rolling of the earth's surface. It is usually what happens when two blocks of the earth suddenly slip past one another, or break apart from each other as a result of tension caused by prolonged energy build up.
GLOBAL WARMING:is the increase of Earth's average surface temperature due to effect of greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. This is a type of greenhouse effect.
