Agriculture Science is the science of crop production and its improvement. In Agriculture Science, scientists focus on research and development on various aspects of crop technology and production.
Crop improvements include:
1. Irrigation Management as a production technique
2. Minimizing the growth of pests
3. Transformation of raw products to end-consumer products
4. Prevention of adverse environmental effects (e.g. waste management and soil degradation)
5. Supply and demand for food in a global basis 6. Crop quantity and quality 7. Study of other fields of agriculture (e.g. soil science) </span>
The Aral Sea has shrunk in size because of heavy irrigation. The correct option among all the options that are given in the question is the third option or option "C". The Soviets used the river waters feeding the Aral sea for the purpose of cotton plantation and this destroyed the Aral Sea.
They are located in Iran.
B) Materials in Solution is NOT a process of a stream load
Streams must start somewhere. Streams are formed by having
sufficient water supply. The supply comes from rainfall and
underground reservoirs. The area that initiates the stream
supply is called the headwaters. Many times headwaters start
in the high elevations. As the water moves down through the
mountains, the stream’s pathway is formed. As streams evolve, the path of the stream starts to curve. The
curving of a stream channel is known as a meander. As meanders
develop, they become broader and larger. Eventually,
there are enough material deposits to form a blockage of two
meanders. This development causes the formation of an
oxbow lake.
Though the region doesn't receive much water during the rainy season, the Gobi receives more moisture during the winter. The Siberian Steppes, north of the Gobi, are responsible for much of the snow that appears on the desert. High winds sweep the snow from the Steppes, distributing it over the dunes of the Gobi during the winter months. Because most of the desert is actually rock rather than sand, however, even this extra moisture has little effect on the region's ecosystem.
<span>These high winds are also the major cause of the temperature extremes common to the Gobi. Both cold and hot air are swept across the desert unhindered. The environment of the Gobi can be harsh and unforgiving, but the area remains an important piece of history and culture to the world.</span>Most deserts suffer from rapid changes in temperature throughout the year, but the Gobi has a climate of extremes. The temperature has been known to shift 60 degrees Fahrenheit in as little as 24 hours. It can get down to minus-40 degrees in the winter, and as hot as 122 degrees in the summer. Though the desert only receives an average of 7.6 inches of rainfall per year (compare that to the Amazon Rainforest which recieves 9 feet), but that's not the only precipitation. Thanks to region's height above sea level (up to 5,000 feet in some areas) and northerly position on the globe, it's not unheard-of to see frost or even snow atop the dunes occasionally.
