  2. 2. Acidrain<br />Acid rain is a rain or any other form of precipitation that is unusually acid. It can have harmful effects on plants, aquatic animals, and infrastructure through the process of wet deposition.<br />Before<br />After<br />Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids.<br />
  3. 3. Hurricane/tornado<br />A tropical cyclone or hurricane is a storm system characterized by a large low-pressure center and numerous thunderstorms that produce strong winds and heavy rain and a tornado is a violent, dangerous, rotating column of air that is in contact with both the surface of the earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud.<br />
  4. 4. Tsunami<br />A tsunami or tidal wave is a series of water waves caused by the displacement of a large volume of a body of water, usually an ocean.<br />
  5. 5. Drought<br />A drought is an extended period of months or years when a region notes a deficiency in its water supply.<br />
  6. 6. Earthquake<br />An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves.<br />
  7. 7. Ice melting<br />The temperature on earth's surface is increasing which leads to global warming and so the ice is melting.<br />
  8. 8. VolcanoEruption<br />A volcano is an opening, or rupture, in a planet's surface or crust, which allows hot magma, volcanic ash and gases to escape from below the surface.<br />
