Venus, Earth, and Mars have very different greenhouse effects. Venus, being the second planet from the sun, is naturally going to be warmer due to its increased bombardment of solar energy. The temperature on Venus averages about 460 C, but this insane temperature is not due solely to the sun 's energy, it is also due to the fact that Venus has an atmosphere that is near 100x more dense than Earth 's, stopping the Sun 's heat from ever escaping. Venus 's atmosphere also happens to be composed of about 95% of carbon dioxide, a well know greenhouse gas, and when coupled with an extremely dense atmosphere creates perpetual acid cloud coverage. Venus 's location in the solar system, its perpetual cloud coverage, and dense atmosphere made of CO2 …show more content…
Its atmosphere is 100x less dense than earths allowing the outgoing heat to slip through easily. Although Mars ' atmosphere is also composed of about 95% CO2 the atmosphere is too sparse to have any marginal effect. Mars also happens to be the 4th planet in the solar system and experiences less solar energy from the sun than Venus and Earth. All these properties culminate into temperatures of about -60 C.
Earth is essentially the middle man in this comparison. The atmosphere is not too dense and not too sparse and not composed of an overwhelming amount of greenhouse gases. The sun does not give Earth too much energy nor does it give too little. This allows a comfortable temperature for life to develop, what astronomers regard as a "Goldilocks planet".
Greenhouse gases contribute to a planet 's temperature based mainly on the density of its atmosphere. Both Venus and Mars have atmospheres that consist mainly of greenhouse gases, but they have very polarized temperatures. The key difference is that Venus has an atmosphere that is 1000x more dense than Mars, which leads to Venus being insanely hot and Mars being a bit chilly.
In short, it does not make sense to take CO2 out of the ground and put it in the atmosphere, in the context of Earth. Our atmosphere is just right to the point that it is susceptible to fluctuations in greenhouse
Greenhouse gases in our atmosphere act almost like a blanket between the earth and frigid space. At lower levels, greenhouse gases trap some heat in our atmosphere while letting other heat radiate out into space. However, as the layer of greenhouse gases around our planet grows thicker more heat is trapped in our atmosphere, less radiates away and the earth slowly heats up.
It’s the year 5013 & Robin is looking through her telescope from her new home planet, Mars. Today was the last day that human kind could be on planet Earth. Due to increasing global warming over the years, Earth was halfway melted, making the core visible & unfit for human life. Robin took her last look at Earth as she packed away her telescope and thought about how her new life would be. Global warming is the gradual increase of the overall temperature of Earth’s atmosphere. It involves the planet as a whole & the people who may cause extreme heating, such as factory workers or people who burn coal. It happens daily, in any place in the world. Global warming has many causes and effects, such as how the sun heats the earth, how climate change affects the atmosphere, how axis tilts affect the seasons, how humans and global warming affect each other, and what global warming actually is.
A greenhouse gas is any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere. By increasing the heat in the atmosphere, greenhouse gases are responsible for the greenhouse effect, which ultimately leads to global warming. (EPA Environmental Protection Agency, 2014)
Earth’s atmosphere originally outgassed the same amount of CO2 as Venus. This CO2 was later dissolved and converted into limestone by Earth’s oceans. Because of this, Earth’s atmosphere is now
Greenhouse gases have both advantage and disadvantage. Greenhouse gases are the several group types of gases that can be absorbing solar radiation in the atmosphere such as carbon dioxide, methane, and water vapor. Approximately 75% of the radiations that come from the sun were absorbed by greenhouse gases in the atmosphere. Moreover, about 50% of radiation that was absorbed by greenhouse gas was radiated downward to Earth surface. So because of this phenomenon sustained the overall Earth’s temperature limited it into the proper amount that all of the living thing can be lived. However, greenhouse gases could be the big deal if there are becoming too much. Since the Industrial revolution happen the human activities, fossil fuel comb...
Carbon dioxide is present in the atmosphere of all three planets. Compared to Earth, Venus has about 218,250 more times carbon dioxide, while Mars has about 23 times more carbon dioxide.
Greenhouse gasses have a big impact on our atmosphere. These gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide. Each greenhouse gas molecule has three or more atoms that are loosely held together and that eventually release the heat energy and it is absorbed by another greenhouse molecule. Many people talk about greenhouse gasses as if they are a bad idea, but they are not a bad thing. Without these gasses the earth would be zero degrees on the surface. However, too many greenhouse gasses can cause higher temperatures in the atmosphere, cause oceans to warm beyond what they should be normally and weather that is unpredictable. The same with fossil fuels that produce a variety of emissions that pollute our planet 's air and water. These pollutants threaten the environment and its
In order to get the latter statement a Russian spacecraft – Venera – was sent to Venus to carry out investigations. Thereupon, it was found that the Venusian atmosphere has an unusual atmospheric structure of two distinct tropospheric areas that carry out distinct chemical reactions. Such structure goes as follows: the upper troposphere is exposed to sun rays thus carries out dissociation related chemical reaction whereas the lower troposphere is protected from the solar light hence traps heat and carries out heat related chemical reactions. In conclusion, such reactions that take place together with the abundant carbon dioxide (CO2) in the Venusian troposphere are vital in order to create species such as oxides of nitrogen (NOx) and produce sulphuric acid (H2SO4) droplets that make up the clouds veiling Venus.
The hottest planet is Venus, though Mercury is the closest to the Sun. Venus atmosphere traps the heat from the Sun, like a greenhouse effect and absorbs it. The temperature on Venus is 465 C. Jupiter is the biggest planet and it also rotates the fastest It two and a half times massive than all the other planets and made up of gases that’s why it’s known as the “gas giant”.
First is a description of the greenhouse effect. The earth’s atmosphere has four layers, or zones, with each having distinct differences in temperature. The troposphere is the first layer surrounding the earth. Within this layer air is continually circulating and moving heat and moisture around the earth. The troposphere is denser than the other layers due to the fact that gravity keeps the majority of air molecules near the earth. This is about 75 percent of all the atmospheric mass. It is also the warmest layer (Cunningham & Cunningham, ...
The distance from the sun affects the temperature of a planet because the closer a planet is to the sun the greater the temperature will be. The planets reflectivity affects the temperature because the more reflective a planet’s surface is the lower the amount of solar radiation that will be absorbed by the planet. The thicker the atmosphere the hotter the temperature of the planet will be because the more it locks in green house gasses, raising the temperature. The more pressure in the atmosphere the hotter the temperature of the planet. As seen in physics the more pressure that is exerted on an object the more the temperature will rise.
This planet is about half the size of Earth, and the second smallest planet in our Solar system. Mars is usually known as the “Red Planet” because of its red color, which is due to the concentration of iron oxide and dust and rock covering its surface, yet it’s the main component is Carbon Dioxide. Mars has a very thin atmosphere, which leads to a wide range in temperatures because it cannot trap solar heat. Hence, Mars’ temperature is a lot colder than that of Earth’s, at about minus 80° Fahrenheit. Mars is home to the highest mountains and volcanoes in the Solar System, such as Olympus Mons (biggest volcano) and Valles Marineris (one of the largest canyons). Mars experiences seasons just like Earth, except that they are twice as long as that of Earth’s. The explanation for these giant mountains is Mars weak surface gravity. Mars has two known moons, Phobos, and Deimos. Mars is currently a very important target for NASA and other space exploration because it is the planet most prone to life, after Earth.
Earth’s climate is determined by the physics and chemistry of its atmosphere. Earth’s atmosphere consists of four layers; troposphere which is closest to earth, stratosphere, mesosphere, and thermosphere. Hardy says, “During the past 100 years we humans, as a result of burning coal, oil, and gas and clearing forests, have greatly changed the chemical composition of the thin atmospheric layer.” There is more carbon dioxide in the atmosphere due to burning fossil fuels. The atmosphere is made up of many gases such as nitrogen, oxygen, and argon. It also consists of trace gases such as carbon dioxide, methane, carbon monoxide, nitrogen oxides, chlorofluorocarbons and, ozone. The trace gases have the greatest effect on our climate (Hardy 5). Up to a certain level, these gases help to keep the planet warm by absorbing certain infrared wavelengths, so that there can be life on the planet. Thus, they trap heat in the troposphere and stop it from escaping to space (Hardy 7). Therefore, the greater amount of greenhouse gases, the more heat trapped in the atmosphere. Earth’s temperature is increasing due to increased levels of greenhouse gases such as carbon dioxide released into the air from burning fossil fuels. The Intergovernmental Panel on Climate Change (IPCC) 2001 report projects “global average surface temperature increases ranging from 1.4 to 5.8 degrees
In a recent political conversation with my stepfather, Keith, the topic of climate change came up. Keith told me that in 2002, NASA came out and said there was frozen ice on Mars, and now 14 years later, they have found that there is flowing water on Mars. Keith’s comment on this was, “Of course there is flowing water! The ice has melted. Mars goes through periods of temperature change just like the Earth does.” After researching on my own, I have found that many planets have these types of changes occur, namely Venus. Venus used to have oceans long ago, but now the surface is completely dried up and scorching hot. You would think this is due to the fact that Venus is thirty percent closer to the Sun than Earth is, but that is not the reason at all.
The amount of CO2 in a planet's atmosphere affects the temperature of the planet. As more and more CO2 builds up in the atmosphere, less heat can escape and the planet gets hotter. The CO2 traps radiation from the sun like a greenhouse. This is called global warming or the greenhouse effect. Global warming is becoming a serious problem and CO2 is the major cause. The earth is now warmer than it has been in 1000's of years. The amount of CO2 deposited in the earth's atmosphere from human activities is expected to double by the year 2050. It could possible increase by four in the future with developing countries, such as China, anxious to improve their standard of living.
