... to take place in order to release latent heat and it is the latent heat that initiates the development of the storm and consequently produces heavy rainfall. When the hurricane reaches its maturity an eye develops in the centre, in the eye there is a relative area of subsiding pressure. Which is what causes clear skies, anomalous high temperatures and light winds. Eventually the eye disappears as a result of the descending air increasing instability, which in turn warms and increases the storms intensity. Around the eye there are towering Cumulo-nimbus clouds. The hurricanes decline as soon as the source of heat is lost/or removed. Although it can take be ...
... to volcanism and erosion. Mars is similar to our moon in the southern hemisphere. This region is referred to as the “Highlands” of Mars. The area is pitted with numerous craters that reach between one to four km above the datum. Ejecta from the impact scatter around the crater making a rim like structure. The northern hemisphere is very low compared to the southern hemisphere. In the north the ground level rarely reaches above one km below the datum. This stark contrast between north and south is thought to have happened 3 Gyr ago. The south was continuously bombarded with meteors. The north would get hit but it would erode or volcanic flows ...
... plant history occurred within the next 50 million years (400-500 million years ago). Some of these developed root systems stems and leaves. They also formed woody tissue, which created stiffer stems, which eventually developed into tree trunks. They became tree-like and up to 40 meters tall, forming the world's first forest. 'The Age of Seed Bearing Plants' was the next stage of plant history where plants were taken to their next step up in the evolution. This occurred around 280 million years ago. This was also the dinosaur era. Earth began to become a lot drier, and these plants began to adapt to the ever so changing climate. These plants developed the ability to ...
... drilling through brass with a dull bit he could produce enormous amounts of heat yet not get very deeply into the brass. This led Mr. Thompson to the conclusion that heat was the product of work, not the invisible fluid caloric. Joseph Black, yet another scientist of the seventeen hundreds, discovered that it took different substances varying amounts of heat to raise one gram of a substance one degree Celsius. He called this specific heat. Mr. Black also noticed that when mercury at fifty degrees is mixed with equal amounts of water at zero degrees the resulting mixture would be only one degree. From this, he concluded that heat and temperature were not the ...
... very reactive and it bonds easily with other molecules it the atmosphere. When and oxygen atom from the ozone reacts with a chloride ion from chlorine monoxide, the ozone molecule is destroyed. So chlorine monoxide is an ozone destroyer. There is always a certain amount of chlorine monoxide in the atmosphere. It is important to remember that ozone is constantly being created and destroyed in the atmosphere. The amount of ozone in the atmosphere is based on these reactions. There are many factors that influence the amount of reactions like season, latitude, and solar cycle. Because of these factors ozone can vary wildly each day. In the northern latitudes there ca ...
... chromosomes and exchange bits of genetic material. In women, X-chromosomes pair, in men, the X and Y-chromosomes separate, and meiosis continues. Otherwise it is not something that happens by the law of nature in which you are randomly chosen in its specific frame of how many times it happens, whom it effects, and how it happens. There is really no specific frame in which it invariably happens. It is known through that it happens during the process of meiosis in which chromosomes split. WHO IT AFFECTS??? Klinefelter Syndrome only occurs in males. This is so because females have a similar condition called Turner’s Syndrome who generally has ...
... in the introduction of the first small hard disk drives. The first 5.25-inch hard disk drives packed 5 to 10 MB of storage, the equivalent of 2,500 to 5,000 pages of double-spaced typed information, into a device the size of a small shoebox. At the time, a storage capacity of 10 MB was considered too large for a so-called "personal" computer. The first PCs used removable floppy disks as storage devices almost exclusively. The term "floppy" accurately fit the earliest 8-inch PC diskettes and the 5.25-inch diskettes that succeeded them. The inner disk that holds the data usually is made of Mylar and coated with a magnetic oxide, and the outer, plastic cover, b ...
... water zone, in a thermally stratied body of water, in which the temperature decreases rapidly with depth. This depression of the thermocline has great effects on the worlds fishing industry. The cutting of nutrient rich therocline water reduces the growth of algae, which in trun, collapses the food chain. Thus, leaving our worlds subsistence and commercial fishermen with out food and money. With the already descendeing food chain on our earth, the warming water also effects the atmosphere, resulting in more extreme temperatures, more rain, and more drought periods, costing more money to our already debted economy, and the world. An example (demonstrated here b ...
... Weather Service. The National Weather Service gives predictions for all of the world through satellite imagery for all countries. Also in recent history many local television and radio stations have made private forecasts for small areas. Meteorologists are people who interpret the weather, the reason I don't say predict the weather is because even though all forecasters have the same information and data at their fingertips, the way that they interpret what is in front of them can be different. Meteorologists receive information from various sources, but their interpretation of the data determines the accuracy of their prediction. Someone might ask, "If fo ...
