Spring And Autumn Essay Example for Free

Spring And Autumn Essay Natural events In spring, the axis of the Earth is increasing its tilt toward the Sun and the length of daylight rapidly increases for the relevant hemisphere. The hemisphere begins to warm significantly causing new plant growth to spring forth, giving the season its name. Snow, if a normal part of winter, begins to melt, and streams swell with runoff. Frosts, if a normal part of winter, become less severe. In climates that have no snow and rare frosts, the air and ground temperature increases more rapidly. Many flowering plants bloom this time of year, in a long succession sometimes beginning even if snow is still on the ground, continuing into early summer. In normally snowless areas spring may begin as early as February (Northern Hemisphere) heralded by the blooming of deciduous magnolias, cherries, and quince, or August (Southern Hemisphere) in the same way. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, or monsoonal, or cyclonic. Often the cultures have locally defined names for seasons which have little equivalence to the terms originating in Europe. Many temperate areas have a dry spring, and wet autumn (fall), which brings about flowering in this season more consistent with the need for water as well as warmth. Subarctic areas may not experience spring at all until May or even June, or December in the outer Antarctic. While spring is a result of the warmth caused by the turning of the Earths axis, the weather in many parts of the world is overlain by events which appear very erratic taken on a year-to-year basis. The rainfall in spring (or any season) follows trends more related to longer cycles or events created by ocean currents and ocean temperatures. Good and well-researched examples are the El Nià ±o effect and the Southern Oscillation Index. Unstable weather may more often occur during spring, when warm air begins on occasions to invade from lower latitudes, while cold air is still pushing on occasions from the Polar regions. Flooding is also most common in and near mountainous areas during this time of year because of s nowmelt, accelerated by warm rains. In the United States, Tornado Alley is most active this time of year, especially since the Rocky Mountains prevent the surging hot and cold air masses from spreading eastward and instead force them into direct conflict. Besides tornadoes, supercell thunderstorms can also produce dangerously large hail and very high winds, for which a severe thunderstorm warning or tornado warning is usually issued. Even more so than in winter, the jet streams play an important role in unstable and severe weather in the springtime in the Northern Hemisphere. In recent decades season creep has been observed, which means that many phenological signs of spring are occurring earlier in many regions by a couple of days per decade. Spring is seen as a time of growth, renewal, of new life (both plant and animal) being born. The term is also used more generally as a metaphor for the start of better times, as in the Prague Spring. Spring in the Southern Hemisphere is different in several significant ways to that of the Northern Hemisphere. This is because: there is no land bridge between Southern Hemisphere countries and the Antarcticzone capable of bringing in cold air without the temperature-mitigating effects of extensive tracts of water; the vastly greater amount of ocean in the Southern Hemisphere at all latitudes; at this time in Earths geologic history the Earth has an orbit which brings it in closer to the Southern Hemisphere for its warmer seasons; there is a circumpolar flow of air (the roaring 40s and 50s) uninterrupted by large land masses; no equivalent jet streams; and the peculiarities of the reversing ocean currents in the Pacific. AUTUMN SEASON Autumn is when all these colors transition into different levels of reds and browns and become crisp, falling off for children to sweep or collect. If the leaves in spring are bright green, the leaves in autumn are a magnificent red. Spring is the signal that winter has already ended, and autumn is the signal that summer is finally over and done with. For many people, spring lets them look towards summery days and vacations ahead ‘â€Å" while autumn signifies the reality of going back to school and the routines of the most part of the year. Colorful plants and green leaves versus brilliant reds and browns and falling leaves ‘â€Å"an awakening from the cold, and the end of the hot summer heat. The eager anticipation of sunny days and breezy nights, and the stark reality of a vacation ended on a high note. These are usually the things that come to mind when you try to differentiate between the two seasons of spring and autumn.

Classical Conditioning Essay -- essays research papers

Green Light Go, Red Light Stop   Ã‚  Ã‚  Ã‚  Ã‚  Classical conditioning shapes many of society’s common, everyday tasks. Whether we know it or not, many actions we do numerous times a day are a direct result of classical conditioning. To better understand why we act the way we do in society, classical conditioning must be defined and described.   Ã‚  Ã‚  Ã‚  Ã‚  Classical conditioning is defined as: a process by which a previously neutral stimulus acquires the capacity to elicit a response through association with a stimulus that already elicits a similar or related response. Discovered by Ivan Pavlov, classical conditioning is a form of learning. Pavlov revealed this trait when experimenting with dog’s amounts of saliva in response to meat. He started noticing that after many repetitions, the dogs were salivating before the meat was even introduced. Pavlov concluded that some other stimulus that was repetitively associated with the meat was triggering the salivation. This simple concept describes how many actions are carried out in society today.   Ã‚  Ã‚  Ã‚  Ã‚  Many times classical conditioning is not something that is purposefully done, but rather an incidental outcome. Conditioning may take a variable amount of time to occur. For example, humans are not born associating red with stop. As we grow, and ride in cars, we begin to consciously or subconsciously figure out that when a stoplight is red-you stop. Stop signs are red, stoplight...

Non traditional threat to US Essay

In my opinion the most pertinent Non-traditional threat to the US is the economy. It is the single most important, globalized, and un-accounted for problem in the US. The current problem is so bad that the US economy is days away from a (partial) default. This would be the first default since possibly the 1700’s at the founding of the nation. The problem with this is the US green back is the reserve currency of the world (all or most investments are made in US dollars). If the US defaults it will cause a ripple effect that will make the 2008 global financial crisis look small in comparison to the lobal catastrophe that will occur. The reason most investments are in US dollars is because dollars have historically been the most stable currency in the modern age. The US defaulting on its debts has both internal and external effects. The total of US government debt is over $ 16. 9 trillion. (US Debt Clock) Of that debt, $ 4. 8 trillion is owned by governmental agencies. This includes agencies such as the social security (holds over $2. 5 trillion dollars). Of the public debt, foreign investors own $5. 7 trillion. Keep in mind this is Just the actual government debt; effects of a default would be uch bigger. The US reached its debt ceiling in 2012. The US constitution – 14th Amendment, Section 4 – directly forbids the government from defaulting on its debt. Thus to cope with the debt ceiling being reached the government has been taking extraordinary measures in order to pay their debts (for instance suspending investments on individual pension funds). When these measures are exhausted, the government will not bring on a global economic collapse as they default on all their bonds. They will Just be forced to balance the economy – to match their spending with their collected revenue. This is a very different issue (still with its problems) to a full default. What is important is that a full default is likely to not happen. The brinksmanship between the rogue Republicans and the government would only threaten a ‘technical’ default on the shortest-dated US government bonds, because their shorter lives mean their maturity date is nearer than the rest of the government’s ‘safe’ assets. The problem here, as ever, is not whether the federal government is able to repay the principle from these bonds, but the short-term methods used to make these repayments. The US treasury would still be seen as a ‘safe investment’, albeit in more economically uncertain times, and thus bonds would probably rise in price – believe it or not, the US government 10-year bond decreased in price after news that the media reported a default was unlikely. Though we are quick to forget, there have been 17 government shutdowns between 1976-1996 and the debt ceiling is raised almost every year – a full default never happens. This brinksmanship is historically common, and it is the media and politicians that fuel the political fire by indicating that this is the year where it will default.

Comparative Analysis Of A Farmers Market - 2010 Words

For the assignment of comparative analysis of a farmer s market and a grocery store in a low income community, it was a no-brainer where I would go. I didn t need to go online and find a list of farmer s markets in LA and narrow it down by the low income zip code, not when I lived in one. As a resident of a low income neighborhood, I knew exactly where to go: I would go to the Watt s Healthy Farmer s Market. Held every Saturday, whether it rains or shines, from 10 a.m. to 2 p.m., the Watt s Healthy Farmer Market is located in the Ted Watkins Memorial Park, appropriately named after Ted Watkins, the founder of the Watts Labor Community Action Committee (WLCAC). WLCAC is an influencing non-profit community based organization which serves to provide affordable housing, jobs, and social services to the residents of Watts and South Los Angeles, as well as fight poverty and ultimately, increasing the quality of life of the neighborhood. It was organized following the 1965 Watts riots with the support of several labor unions and funded by grants from the government at varies levels. The park was named in 1995 and is a 28-acre facility taking up one whole block with the farmer s market taking place in the southwest corner, conveniently located just a few steps away from one of the park s parking lots. Surrounding the park, are a few interesting things I d like to point out. There are quite a bit of stores, both big and small, as well as several residential homes.
