Why Is the Ocean Blue and Sometimes Green

Have you ever wondered why the ocean is blue or why it is sometimes another color, like green, instead? Heres the science behind the color of the sea.​ The Answer Is in the Light There are a few reasons why the ocean is blue. The best answer is that the ocean is blue because it is mostly water, which is blue in large quantities. When light strikes water, like sunlight, the water filters the light so that red is absorbed and some blue is reflected. Blue also travels farther through water than light with longer wavelengths (red, yellow, and green), though very little light reaches deeper than 200 meters (656 feet), and no light at all penetrates beyond 2,000 meters (6,562 feet). Another reason the ocean appears blue is because it reflects the color of the sky. Tiny particles in the ocean act as reflective mirrors, so a large part of the color you see depends on what is around the ocean. Sometimes the ocean appears other colors besides blue. For example, the Atlantic off the East Coast of the United States usually appears green. This is due to the presence of algae and plant life. The ocean may appear gray under a cloudy sky or brown when the water contains a lot of sediment, as when a river empties into the sea or after the water has been stirred up by a storm.

Paragraph On The State Of Security - 2300 Words

Preamble The state of security in our country is near a grave experience, especially the north-eastern part of Nigeria. A country where the security of lives and property has deteriorated to the Hobbesian state of nature; a situation of anarchy, total lack of law and order, a precarious circumstance of survival of the fittest and the elimination of the unfit, reveals nothing order than O. Henry s banana republic. Such is our situation - suspicion has become the order of the day as the number one citizen of the country has made public confessions. Popular words on the lips of Nigerians are; boko, bomb and bullet. A sure creed for a people in travail hopelessly hoping against hope - looking up to a security outfit that has failed either because it has compromised its stand or it is helpless due to its unsophisticated armaments compared to those of those threatening the unity and integrity of our common existence as a people and a nation. The ugly state of affairs namely insecurity, plus a poverty-stricken populace unsure of the so-called dividends of corruption-bound democracy greased by privatization and the deregulation of the petroleum down stream sector, leaves much to be desired. The Arab spring and the January fuel subsidy protests have a lot of lessons for our nation. Many social critics and analysts have lend credence to this fact. America had predicted 2015 for our break-up as a nation but now, 2030.

The World War II ( Wwii ) Essay - 1875 Words

World War II (WWII) lasted longer and killed more people than the Great War. There was not a fast victory conquered by bombers hitting the heart of the enemy. Air power’s contribution to the allied victory did not represent the ultimate fulfillment of the predictions of interwar theorists. Even though air power had an important role, and many lessons and doctrines emerged after this period, the visions of Douhet, Mitchell and others did not materialized as they expected. In this paper, I will discuss three of the main prophecies: the effectiveness of the strategic bombing, the ability of air power to win the war by itself, and the futility of the use of air power for defense of territory. Strategic bombing was the main prophecy emerged after World War I (WWI). It would avoid the bloody and slow process of ground invasion to hit the enemy will to fight. Theorists offered efficiency and speed instead of attrition and carnage. In the industrial societies, destroying the weapon industrial plants and frightening its work force in theory implied leaving the enemy without means to fight.2 However, during the first campaigns of WWII was evident that it was not so simple to reach the targets.3 Thus; the prediction reflected an optimist perspective, obviating the difficulties before arriving to the point. Even in the best case, without significant air opposition, altitude was inversely proportional to the accuracy of the bombs due to limitations of crew training and technology.

Now you know. It may happen again. My job is to take care of you. I was appointed to do that by God. I will kill anyone who touches you. Do you understand? † The lives of the man and the boy truly are worst-case scenarios. How many times have we wondered at one point or another in our lives if we’d be willing to take a bullet to the head or kill someone for our families’ or loved ones’ sake? These characters have been placed in that exact situation. They live in a post-apocalyptic world where human beings have been stripped to their core and have been driven to extremes by their innate need to survive, and they are no exception. The father is carrying out all those â€Å"what ifs† – he is doing what he must to keep his son safe. Truly, the only thing that keeps them going is their love for one another. â€Å"A symbol of the goodness in human perseverance and hope is the fire that the father assures his son they carry. As a good guy, the man and the boy carry the fire internally, meaning that they strive to live under all circumstances. † â€Å"The man does not consider acting violently in defense of his sons survival evil.

Son sees dad as selfish (e. g. alues his sons life) while son himself is selfless†¦ the father does not trust any other individual they see or meet. Only his son extends his humbling trust in others, offering to help Ely and the thief without first determining whether their intentions are malicious. the boy does not understand the need to hurt others in any circumstances, even when they may pose a danger to his own survival or have already hurt him. For example, the boy pleads for his father to spare the thief and, even more, to help him. End Event Father Dies: Thesis:
