Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides reacting with water molecules in the atmosphere to produce acids that can harm plants, animals, and infrastructure through wet deposition. Hurricanes and tornadoes are powerful storm systems - hurricanes form over warm ocean waters and have strong winds while tornadoes are rotating columns of air between the ground and storm clouds. Tsunamis are large sea waves caused by displacement of water in the oceans, usually triggered by earthquakes or volcanic eruptions under the sea. Drought occurs when a region experiences a prolonged shortage of water, while earthquakes are caused by a sudden release of energy in the Earth's crust that generates seismic waves. Global warming is raising temperatures and causing

2. Acidrain 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. Before After Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides which react with the water molecules in the atmosphere to produce acids.

3. Hurricane/tornado 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.

4. Tsunami 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.

5. Drought A drought is an extended period of months or years when a region notes a deficiency in its water supply.

6. Earthquake An earthquake is the result of a sudden release of energy in the Earth's crust that creates seismic waves.

7. Ice melting The temperature on earth's surface is increasing which leads to global warming and so the ice is melting.

8. VolcanoEruption 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.
