drought: Activity1

Activity1

yesterday we did an activity on direct heating. it showed how snow, soil, and water are affected by the heat and cooling process.we showed how the temperature for each one changed through out the 10 min. we did this for. this relates to drought because the heat is absorbed by the soil which then heats the ground. this causes the water in the ground to evaporate, this makes the trees and plant life die because they don't have water to keep them alive.

drought

There are a lot of issues that are affecting our climate today and one of them happens to be drought. A drought is a period of drier-than-normal conditions that results in water-related problems. A drought happens mostly around hot, dry, and places by the equator. These places that are affected by drought are mostly in India, Iran, the U.S, west and South Africa, Brazil and Australia. In these countries the weather is warm most of the time so there fore the sun is out making the temperature go up. In most of these places the temperature is hotter then ours that makes the water and land dry up.

Scientists say that droughts are caused by warm, tropical masses of air descending to the earth. http://library.thinkquest.org/J001550F/Droughts2.htm
“Generally, rainfall is related to the amount of water vapor in the atmosphere, combined with the upward forcing of the air mass containing that water vapor. If either of these are reduced, the result is drought. Factors include: Above average prevalence of high-pressure systems, Winds carrying continental, rather than oceanic air masses (ie. reduced water content), El Nino (and other oceanic temperature cycles), Deforestation, Climate change has a substantial impact on agriculture [18] throughout the world, and especially in developing nations.[19][20][21]” http://en.wikipedia.org/wiki/Drought.

We humans also have something to do with why there is drought in the world today. When we do things at home or anywhere that has to do with water we never stop to think what we are wasting because we are so use to thinking that water will never run out. When we take a shower or bath we are using so much water to fill the tub or to run over our bodies thinking that it isn’t anything. Well it is something and we need to take shorter showers and not take baths all that often. Washing cars, dishes, cloths, filling up a pool all take water in order to get them clean. But why waste your car all the time or wash cloths that don’t need to be washed. All you are doing is wasting water that other people in other countries are dieing for literally.

Some weather conditions that are needed in order for a drought happen is very dry and hot weather in a year where they are to get little rainfall. This alone leads to a rapid increase of drought. The lack of precipitation along with very high evaporation levels leads to deteriorating crop conditions. . When this happens our dirt that was once good for planting is now dry like clay. Animals can’t drink, we can’t drink, they can’t eat, and we can’t eat because there is not enough water to grow food and drink. These conditions cause Hunger and famine, Thirst, dehydration, Disease, Wildfires, weight loss, and the worst of them all death. Our environment is impacted also not just humans. If there is no water then our lakes, rivers, ponds, and any other form of water for fish will go down. They wont be able to live and we wont be able to fish. There for is business depend on fishermen to bring them fish to sell they wont be able to because there wont be that much for them to catch.

There is one way to predict a drought and that is through monitoring the rainfall, river flow and soil moisture. “This depth of information, along with historical information on El Niño and La Niña weather patterns, enables NIWA scientists to provide a comprehensive assessment of the likelihood of flood or drought in any given area of the country.” http://www.niwa.cri.nz/edu/students/drought Droughts are issued over the t.v. someone from the department of environmental protection will call in or write a letter stating that they need to tell the people of those countries that will be effected by the up coming drought.
