Various religions and cultures throughout history venerated lightning as a symbol of power, yet the physics of this phenomenon remained an enigma until recent centuries. The hunt to understand began with Benjamin Franklin’s determination of lightning as a form of electricity in 1752, when he proved his hypothesis by flying a kite during a thunderstorm. Yes, Benjamin was right in proving that lightening was electricity, but the question is how is that electricity turned into lightning or how is it generated? There are three parts that play a big role in the creation of lightning; the first big one being the water cycle, the second one is the buildup of static electricity that occurs in a cloud and last is how the lightening is discharged. The formation of clouds play an extremely important part in the creation of lightning, but first one needs to understand how clouds are formed before understanding how lightning works. The water cycle has two main stages that are essential to the creation of clouds; the first one is condensation and the second one is evaporation. Firstly, evaporation occurs when water heats up and turns to vapor. The source of the heat is usually the sun. Water turns to vapor because when water heats up its molecules start moving rapidly. Due to the heat, water vapor will rise from the ground and as the vapor gets higher in the atmosphere it starts to cool down and condenses; the higher up in the atmosphere the cooler the temperature. The vapor condenses because it undergoes a process called condensation which is when water goes from a gas or vapor back into a liquid. The vapor turns into droplets of water high in the atmosphere and form clouds. The more condensed water the heavier and bigger the cloud will ... ... middle of paper ... ... one would have to understand the components of atoms, the water cycle and how opposite electrical charges attract. Evaporation and condensation are what form the cloud and the constantly evaporation and condensation within the cloud that causes electrons to fall on the bottom of the cloud creating separation of charges. Once they cloud builds enough charges it starts to effect earth’s surface by pushing the entire negative charge back and leaving the surface with a positive charge. The strong electrical field forms a bridge from the cloud to the surface of earth by ionizing the air called step leaders. Once the upward streamers that are on earth’s surface connect with a step leader, a current is released and a flash of lightning is discharged. Following the flash of lightning a loud roar of sound that’s caused by air spreading rapidly due to heat is called thunder.
“Go on with what your heart tells you, or you will lose all”. This quote, spoken by Percy is a repetitive thought that he uses in his quest to persevere to the end. From movies, to stories, to plays, the hero undergoes a journey, that is universal in nearly all. This journey is referred to as the Hero’s Journey and consists of three stages with other elements within each stage, and was recognized by Joseph Campbell. The pattern of the journeys allows a universal audience that all, young and old, can relate to. A broad description of the monomyth includes the hero leaving their ordinary life, commencing the bulk of the journey, and returning home. In the movie The Lightning Thief by Rick Riordan, the protagonist Percy Jackson presents discernible
My original thought when comparing Percy Jackson and the Olympians: the Lightning Thief the movie and Classical mythology was that there would be many more references to the myth of Perceus than any other myth throughout the movie in its entirety. That’s where I was wrong. After watching the movie again and researching the different hero myths my opinion has changed. My new thoughts are that the movie is not influenced by the myth of Perceus any more than other hero myths. The movie ties together many different heroes’ stories and mixes them together to make a wonderful story about a young boy. The movie was based on a book series written by Rick Riordan.
Tornadoes form from wind shears. Wind shears form from warm air that is found at ground level; when it’s raised, the updraft meets a down draft of cooler air that is moved in the opposite direction of the warm air. When both are pushed towards the Earth, this creates wind shear. A spinning tube of air, created from wind shear; tilts upward into a vertical position, as the updraft sucks up moisture from the ground and into the sky. As the warm air cools high in the sky; this produces condensation. The condensation then produces thunderclouds, which rise to 30,000+ feet. The spinning formations of air are then trapped and lifted into the thundercloud. This begins as swirling motion and as continued (if the winds remained viable), a supercell will form. Mesocyclones as they are known are a rotating cloud. If these rotating clouds run into humid air it will spi...
There are numerous stages that take place simultaneously in the hydrologic cycle and this includes evaporation. This is when the water alters from a liquid state into a gas. The damp air from the water rises into the atmosphere and when it cools, the vapor condenses and shapes into clouds. But those billows are not the only form the vapors make; it can also materialize as dew, fog and mist, which blanket the Earth, characteristically on a rainy or humid day. Evaporation takes place when water changes from a liquid state into a gaseous state, and ascents out of the pores of the earth and into the atmosphere as a vapor (“How”). While evaporation is taking place, condensation is also occurring. When the temperature in the air plunges, the clouds become heavy and as a result they relieve themselves of the extra weight, which is called precipitation. This produces rain, hail, snow and sleet, conditioned upon the temperate. As the precipitation falls, it enters the surface of the ground and percolates into the soil, which is called infiltration. The more porous the land is, the more the infiltration can take place. However, the ground cannot hold all of that water and floods. The excess rainfall, which is also called runoff that has not been absorbed makes its way into bodies of water, such as small ponds, rivers, lakes and parts of the ocean (“Summary”).
Throughout history and literature women are often referred to as birds, especially those of domesticated species. Women being referred to as a pet corresponded to the rise of patriarchal society, “… from this point, civilization has seemed to trap women in stereotypes related to nature which are domesticated, like caged birds” (Clark 342). Women had to fit into the roles society formed for them, trapping them in a lifestyle not appealing to all women. In The Awakening, Kate Chopin uses avian symbolism to emphasize Edna’s entrapment, so as to show the stages of Edna’s awakening.
Directors have been turning books into movies for many years. Fans love seeing their favorite books become screen productions. Often the movie is a complete failure that barely resembles the books and causes an upset among fans and book authors. However, once every few disappointments there lies a good film that does the book justice. A film that satisfies the fans and the author. “Percy Jackson the lightning thief” is a story about a young boy who tells a story about being a half blood. A half blood is a child that is half human, and half God. Percy discovered his unique bloodline while simultaneously discovering that his life was in danger because of it. He goes to a camp called camp half-blood where there were others
The novel The Lightning Thief, written by Rick Riordan, tells the story of a 12 year-old boy named Percy Jackson, who struggles with school, bullies, and supernatural powers. The story takes place in modern-day New York and is narrated by Percy Jackson. Percy Jackson lives in an apartment in Manhattan, New York with his mother, Sally Jackson, and his stepfather, (Smelly) Gabe. Percy goes to Yancy Academy, a boarding school, where he shares a dorm with his strange friend, Grover Underwood and puts up with Nancy Bobofit, the bully. Throughout the story, Percy deals with repeating conflict including his struggles with school, bullies, nature, and supernatural powers at work around him, making this story a tense and exciting adventure.
One thunderous afternoon on June 1752, Benjamin Franklin conducted what is known today as the “Kite Experiment”. He wanted to prove that if one object was electrical, the energy from that object could be transferred to another object, therefore being classified as electricity and lightning. With his son William, Ben took a string and attached the kite to it, then he attached an iron key to the kite. Next, they tied a thin metal wire from the key and put the wire inside a Leyden jar which stored all the electrical charge. His experiment profitably showed that his accusations were correct. Many other scientist tried the same experiment and were electrocuted, but Ben Franklin was the lucky one. He changed the world of science.
... important technique the other used in this book. She had used foreshadowing to tell us that Robert was going to go for Edna and that Edna was going to swim way too far out. For example, Madame Ratignolle was telling Robert that Edna was not one of them and Edna would take his flirty actions seriously. Chapter VIII, page 19.
“Percy Jackson and the Lightning Thief”, is a movie adaptation of the similarly titled novel “The Lightning Thief”, written by Rick Riordan. This movie was directed by Chris Columbus and was not well-received during the time in which it was released, due to its substantial differentiation from the novel. Throughout this film, it is clearly made evident that there are several differences between this film adaptation and the original novel that this movie was based upon. The most apparent of these differences can be found in the development of the central characters of the narrative and the sequence of events that occur throughout this movie adaptation. Due to the differences that
Once upon a time high above the earth, fluffy white clouds drifted through the atmosphere. In the clouds lived a family Droplet of water, round and content with life. For as long as I could remember, I spent my days lying on my back, relaxing and soaking up the sun's warm rays. One day, I took my usual place in the sun but the light didn't seem to be as bright. In fact, as the day went on, it grew darker and darker, loud claps of thunder shook the cloud, and the Droplet felt as if he were getting so heavy he could hardly move. This is called precipitation.
1. According to the USA Today Tornado Information website, a tornado is a "violently rotating column of air in contact with the ground and pendant from a thunderstorm." Therefore, thunderstorms are the first step in the creation of a tornado.
Rain forms when water vapor condenses and falls, the more it condenses the more it falls. Some raindrops are not pure and are filled with other materials, this is known as acid rain. Acid rain is a huge problem all over the world. Acid rain is mixture of chemicals, like fossil fuels and the atmosphere, it then comes down as rain, snow, hail, and sleet. The burning of fossil fuels is the main cause of acid rain. When oil and coal are burned they create sulfur dioxide, nitric oxide, and nitrogen dioxide. (" Acid Rain | US EPA") The mixture of all the chemicals and heavy winds blow the compounds across many borders.
A thunderstorm that produces large amounts of precipitation which reaches the ground should have deep moisture stratums in unstable conditions, causing enough convection to be restricted to the electrification level of the atmosphere, or being lifted by orographic or frontal systems (Rorig and Ferguson, 1999). However, some thunderstorms produce small amounts of precipitation or none. Colson (1960) explained this phenomenon as a result of high-level thunderstorms with high cloud bases where the appropriate conditions for triggering lightning flashes accompanied by precipitation are situated in the upper levels. Rorig and Ferguson (1999) analysed the synoptic patterns of dry thunderstorms and concluded that low moisture levels in the inferior part of the atmosphere coupled with high instability, leads to the evaporation of precipitation prior to reaching the ground level, this way reducing the moisture content of the underlying surface.
It was warm that day, but as the sun began to set it began to cool off. This led to a storm coming right at us. From our perspective, we were able to watch the storm form and start to come over us. It was amazing to have the colors of the sunset mixed with the clouds forming across the sky. Eventually, the storm reached us. We could see the rain starting to come down, soon reaching the edge of the lake. As it worked its way across the water, it looked as if a wall was coming at you finally just soaking you with the full force of the rain storm. There was another storm that occurred on the same trip, but this one came out of no where. We were outside in an open area playing badminton in our swim trunks. Then all of a sudden it started raining, but we continued playing anyway. Soon though, it started to hail, starting with just tiny pebbles eventually getting to be marble sized at its largest. This was by no means a dangerous hail storm, but it made me think about the formation of hail. This hail, started in the clouds as a water drop, then began to circulate through the cloud. Eventually it reached a specific size where the cloud could no longer hold onto it and it fell all the way down to the earth plopping down harmlessly on the ground. It truly is amazing how all these things happen
