Large cities have their own climatic conditions. To what extent is this true? (40 marks) Large cities have their own climatic conditions and can be referred to as having a micro-climate. Micro-climates are small scale variations in temperature‚ precipitation‚ humidity‚ wind speed and evaporation that occur in an environment. This would therefore suggest that the statement is in fact true. Large cities create their own climate and weather which is known as the ‘urban climate dome’ within which weather

soil. Therefore‚ resulting in arid fields. In the 1930‘s there was huge drought in the Great Plains. A decreased amount of precipitation was another main cause of the Dust Bowl. Without precipitation‚ it is very hard to grow crops. The Great Plains already has a semi-arid climate and without the much need rain‚ this area turned into a “bowl” of dust. The average precipitation according to John Wesley Powell is 20 inches of rain annually (doc E). As the years pass‚ the annual rainfall for Dallam County

regions where there is a complete seasonal reversal of winds. It is mainly found beyond the equatorial region between 10° and 25° North and South of the Equator. On-shore summer winds blowing from over tropical warm oceans generate the abundant precipitation‚ while the off-shore winds from over land make the weather dry during winter. The most clearly defined monsoon climates are located in the coastal areas of the eastern and southern Asia. For example‚ India‚ Burma‚ Bangladesh‚ Indochina‚ Southern

10. The gravimetric determination of nickel in alloys Gravimetric analyses belong to the most precise‚ because contemporary analytical balances make possible determination of the mass of a sample with great accuracy. In these analyses one should obtain high purity compound of the analyzed element or a compound directly obtained from the analyzed substance). This reaction has to be exactly stoichiometric. It is also important that the weighed compound was non-hydroscopic and stable in air‚ it also

but only a few days without water. Disease Drought limits the amount of clean water for drinking‚ public sanitation and personal hygiene‚ which can lead to a wide range of life-threatening diseases and sickness. Wildfires The low moisture and precipitation that characterize droughts can quickly create hazardous conditions in forests and across range lands‚ setting the stage for wildfires that may cause injuries or deaths as well as a large amount of damage to property and already shrinking food supplies

of continents between 20o and 40o north and south of the equator. Humid Subtropical climate is known for hot humid summers and mild. The rain falls throughout the year. The regularly high temperatures evaporate water‚ which causes humidity and precipitation. The high humidity in this region makes summer temperatures feel even hotter. Humid Subtropical areas usually experience strong storms such as tornadoes and hurricanes. Tropical Wet/Dry Tropical Wet/Dry is found near the equator‚ usually

thousands to millions of years ago and are dated by measuring how much uranium has decayed into thorium for each layer. For example‚ one of the world’s largest cave of speleothems is the Carlsbad Cavern in New Mexico‚ and it provides a record of precipitation for that general location. When water comes through from the ground above and into the cave‚ minerals are brought along with it‚ becoming solid mineral deposits such as stalactites‚ stalagmites‚ and flowstones. Layers accumulate over time and would
