The Pros And Cons Of Earth's Atmosphere

Improved Essays
The Earth’s atmosphere consists of a variety of gases. Nitrogen is the most abundant and makes up 78% of the overall volume. Additionally the atmosphere comprises of Oxygen (21%), Argon (1%), Carbon dioxide (0.04%), traces of other noble gases and water vapour (0.06%). The amount of water vapour present at a given time varies, hence an exact value cannot be determined.

It is essential to understand both the benefits and the possible drawbacks of the atmosphere as this in turn allows observations to planned and executed successfully.

Primarily the Earth’s atmosphere acts as a protective layer. It does this by absorbing harmful electromagnetic waves and radiation. Furthermore it regulates surface temperature, allows the formation of liquid

    Part A Me Text Statement A A 1. If UV intensity levels doubled, mutations in animal cells, skin cancers, and cataracts would increase. “The intensity of UV radiation reaching the Earth’s surface doubled—levels that would increase DNA mutations in human and animal cells, suppress our immune systems, and increase the incidence of cataracts and skin cancer.”…

    Venus has an atmosphere consisting of 95.5% Carbon Dioxide and 3.5% Nitrogen, although other minerals can be traced such as; Carbon Monoxide, Helium and Argon. The amount of Carbon Dioxide in Venus's atmosphere causes a severe greenhouse effect, lifting the temperatures to about 870 Fahrenheit and -365 at night! The Greenhouse Effect is when heat gets trapped in the clouds, causing the body to warm up. Also it's atmosphere is very reflective.…

    developing his ideas? Tragedy of the commons can be defined as an economic theory within a shared resource system where individual users act independently according to their own self-interest contrary to the common good of society by depleting or spoiling that resource. Garrett Hardin explains the tragedy of the commons through an example of herdsman with cattle on the common and each herdsman seeks to maximize their gain. With each additional cattle added to the common there is a positive (proceeds from the sale of an additional animal, +1) and a negative (overgrazing of the common, -1) component (Hardin, 1968).…

    The first and very last layer in our atmosphere is the exosphere and has no breathable air and is extremely cold, below that lies the thermosphere that has very hot molecules that capture the radiation becoming charged and increase in temperature, but because they are scattered and not packed in tightly they are unable to transfer the heat, The next bottom ;layer is the middle layer known as the “mesosphere” where all the gasses are mixed , followed by the stratosphere that contains the very well known ozone that captures intense UV Rays from the sun which protects our atmosphere known as the troposphere. Within the troposphere the weather and temperature is constantly changing and contains ¾ of the atmosphere 's mass. , it 's the ideal atmosphere to live in because it produces oxygen and weather that aids life to flourish. There is one more additional layer that is actually vertical and overlaps the exosphere, thermosphere ,mesosphere and the earth 's magnetic field that causes the gasses within this portion of the atmosphere to become highly excited by the energy emitted from the sun, charging its…

    How has our atmosphere changed over time? Our atmosphere has changed vigorously over time. Anyway, for the past 200 million years, the atmosphere has remained the same generally. Scientists theorize that Earth’s early atmosphere was mostly created by the volcanic activity back then; they say that the volcanic activity was very intense for the first billion years on Earth.…

    The Earth is a part of the solar system and it has been influenced by its elements since it was formed. The solar system was formed from a large nebular cloud. This nebular cloud began to spin producing energy due to the collision between particles. The composition of these colliding particles included metal-rich fragments such as iron meteorites, rocky fragments such as stony meteorites, and icy fragments such as comets. The solar nebula grew hotter and denser, forming a disk of gas and dust at its center.…

    Numerous studies have been done to determine how pollution is affecting our earth, and the humans who live on it. The Environmental Protection Agency (EPA) was developed by President Richard Nixon on December 2, 1970. The United States created the EPA for the purpose of protecting human health and the environment by banning and limiting harmful pollutants by means of laws and testing standards. There are three main areas the EPA attempts to monitor and protect; those three main concerns are air, land, and water pollution. Since it was formed, the EPA has passed major laws that have helped improve our earth’s quality.…

    Module 8 Meteorology and Tornadoes Meteorology, the study of the atmosphere, has been in place from the time when Aristotle wrote his book Meteorologica in 340 BC. Modern meteorology, which took a more analytical approach, began in the early nineteenth century. At that time, meteorologists were armed with devices such as barometers, thermometers, and hygrometers. Though, at the time, they didn’t have a full understanding of their importance and usefulness, they used the tools to record the changes in the troposphere. “As John Herschel, the most celebrated British scientist of his generation, contended, even if a person could not follow the details of a mathematical demonstration, verified predictions could still lead to the conviction that…

    Humans have relied on accessible sources, such as books, scholarly journals, and articles, in order to learn or obtain information. Humans can also learn through another medium: nature. Nature has delicate and majestic works of art available to be observed and studied. Works of art such as mountains, waterfalls, and rainbows are able to captivate the human mind on a daily basis; however, nature is responsible for more than aweing humans with its immeasurable beauty. Through a strong connection via nature, a human can effectively learn how to be more tranquil and peaceful, value and appreciate the smallest forms of life and become more cautious and protective of the environment.…

    Some people may be looking at my experiment and thinking that evaporation, evaporation rates, different amounts of sugars and chemicals, sunlight, and the fact that they grew mold wasn’t a very exciting experiment, but there is a lot more to all of it. There is a lot of things I was wondering throughout this experiment and I did some research to answer my own questions and that is what I am going to share with you right now. Let’s start off with evaporation. Well, what really is evaporation?…

    In addition, the combustion of fossil fuels has also caused the atmospheric concentrations of sulfate aerosols to have increased. Greenhouse gases tend to warm the atmosphere and, in some regions, primarily in the northern hemisphere, aerosols, tend to cool the atmosphere. The weight of scientific evidence suggests that the observed changes in the earth’s climate are, at least in the part, due to human activities : climate models that take into account the observed increases in the atmospheric concentrations of greenhouse gases, sulfate aerosols and the observed decrease in ozone in the lower stratosphere, in conjunction with natural changes in volcanic activity and in the solar activity, simulate the observed changes in annual mean global surface temperature quite well. This, and our basic scientific understanding of the greenhouse effect, suggests that human activities are implicated in the observed changes in the earth’ climate. I will use this current issue in my research to provide causes of global climate change as the result of human…

    As Shaftel said, “We live in a greenhouse.” The radiation that pours out of the sun every second toward the Earth is filtered through the many layers of the Earth’s protective layers. It filters through the magnetic field, which the Earth creates from its metal core. This rids the Earth from dangerous charged particles. Then the sun’s energy goes through the atmosphere and filters out other higher-level radiation.…
