Biomes and Climate Change by vburnin The biome I researched is the arctic tundra 1. Climate change has had several impacts on the abiotic factors of the arctic tundra. One of these factors is the length of the seasons, winters begin late and springs come earlier. It has been observed that changing world temperatures effect colder places the most. Rising temperatures in the arctic tundra have led more permafrost and snow to melt than usual causing the tundra to be converted to wetlands.
However, since the side of the mountain is very steep, the snowboarder must prevent himself from going too fast and losing control. He does this by skidding his board on the snow, in a controlled zig-zag pattern (shown in the first picture). This creates frictional resistance with the snow and prevents his speed from reaching dangerously high levels. A common snowboarder stunt is to jump off a helicopter and land on the side of a mountain, before racing down. The landing force experienced by the snowboarder is reduced because his normal velocity component relative to the mountain surface, just before landing, is small.
Warm air can also rise to form clouds, and blizzard snows, as it drifts up a mountainside. Blizzards can cause power outages and make temperatures inside of homes drop dangerously low. Strong winds combined with a temperature just below freezing create a miserable chill factor. A chill factor is what the human body ‘’feels’’ rather than what the actual temperature is. This dangerous condition can result in frostbite or hypothermia, which can be deadly.
In consideration of the reader of this paper what can be written about this accident that would be of interest not commonly found in the accident report. This paper will address, why this accident was selected, the factors that lead to the accident such as Weather, Crew experience, Air Traffic Control, maintenance and the lessons that can still be learned from this accident some thirty years later. First off, let’s talk about why this accident was selected. This accident was selected mainly due to a personal connection, Air Florida Flight 90; a Boeing 737-222 drew my attention, it’s commonly known as the airplane that crashed into the Potomac River. On January 13, 1982 while traveling as a newly recruited U.S Air Force Airman flying on Air Florida that very same day.
Windchill risk factors include riding in open vehicles, exposure to propeller/rotor-generated wind, running or skiing, and altitude exposure where there is little tree cover. The primary symptom indicative of frostbite is Numbness in affected area. There may also be tingling, blistered, swollen, or tender areas, pale, yellowish, waxy-looking skin (grayish in dark-skinned soldiers). Frozen tissue may feel wooden to the touch. Monitoring air temperature and wind speed and using the windchill index is the only way to determine the relative risk of frostbite.
The blizzard on January 12, 1888 will forever be known as one of the most disastrous storms in history. The storm earned the name “the children’s blizzard” because so many children lives were taken in this malicious storm. Could something have been done to prevent such a large death toll? Yes. If the proper steps had been taken to warn the people of the approaching bad weather, then many could have taken the necessary precautions to ensure the safety of their family and livestock.
Airport security is an important asset around the world, but also establishes problems to privacy guaranteed in America, sparking a great debate between safety and privacy. Directly following the attacks, The Federal Aviation Administration (FAA) ordered all U.S. planes to land (Gard 22). The U.S. military began patrolling American skies (Roleff 70). Airports employed stricter rules, including the prohibition of curbside check-ins, vehicles parked within seventy-five feet of terminals, plastic knives at food outlets and nail clippers in carry-on bags in airports, and the allowing of random searches of vehicles entering parking garages, extensive searches of luggage, and only ticketed passengers through boarding gates (Gard 34). The Transportation Security Administration (TSA), which “protects the Nation’s transportation systems to ensure freedom of movement for people and commerce” was created (“Who We Are”).
The consequence of derelict foreign objects could result in Foreign Object Damage (FOD). FOD is the result of FO ingested into an aircraft jet engine, slung out from propellers or even slung up from landing gear and striking the aircraft and causing
Marquita Rice ENG121 English Composition I Week 5 Assignment 05/15/11 The benefits of cold vs. the benefits of heat ( Topic taken from homeworktips.about.com/od/essaywriting/a/compare.htm) The cold and heat are both weather seasons. The cold is in the winter. There is snow and ice. At times it can get so cold that lots of places can be shut down. There are blizzards.
Since the temperatures have started to rise, the ice that they once lived on has melted and they are having a very difficult time surviving. People have increased the temperature of the Earth by contributing their pollution. Burning fossil fuels and forests has been the biggest issue amongst us all. Simple changes could help in simple ways but the fact is that since it is a global issue, the world has to be involved in order to make a difference. The United Nations has contributed in this way by holding meetings to discuss the climate changes throughout the world and what can be done to help.
