Essay about atmosphere evolution of rocky planets

Venus: the atmosphere for venus is mostly filled with carbon dioxide and thick clouds of sulfuric acid cover the planet.it is told that you would not be able to breath the air, that the atmosphere would crush you with the weight, and you would burn to a crisp immediately. Even though it's the second closest to the sun it is the hottest planet that there is in this universe, that i know of. Venus is also known as the goddess of beauty and love for the Greeks and Romans. The next planet that

Jupiter is a gas planet with a possible chance of a core. On the outside of Jupiter, what we can see, is its atmosphere. Jupiter’s atmosphere is layered. It contains hydrogen, helium (a

1. Recall chapter 1 that Earth and Venus are so similar in size and overall composition that they are almost twins. Why did these planets evolved so differently? Why is earth’s atmosphere rich in oxygen and poor in carbon dioxide, whereas the reverse is true for Venus? What would happen to the Earth’s oceans if earth were a little bit closer to the sun?

What do you think we would do if someone from anther planet landed in the U.S and claimed it as his territory because he had discovered it? How would you feel about this?

To compare, all three planets have secondary atmospheres that were produced by volcanoes. To contrast, Venus is too close to the Sun, and was too warm for liquid water to form and without liquid water; the CO2 could not settle out of the atmosphere and dissolve into the oceans. This caused Venus to suffer from runaway greenhouse effect and became hot with an extremely dense and vastly insulated atmosphere. Along with this, UV sunlight destroyed the H2O in the atmosphere. On the other hand, Earth had enough distance from the Sun for liquid water to form and precipitate out into the ocean while the CO2 in the atmosphere dissolved into the oceans and was removed from the atmosphere. The trace amounts of H2O and CO2 in the atmosphere create an insulating layer which is enough to keep the Earth at a mild temperature. Out of the three planets, Mars is the farthest from the Sun. It is possible that Mars had liquid water earlier in its history. The CO2 dissolved into water; however, Mars has less mass than Venus or the Earth. Because of Mars’ smaller mass, it has less tectonic activity and Volcanism stopped early in its formation. This did not allow the atmosphere to be renewed from CO2 or H2O

The air is not breathable by humans! Venus's atmosphere also contains traces of extra compounds and elements, such as neon, argon, carbon monoxide, and helium. Atmospheric pressure is over 90 times heavier than that of Earth; sheer crushing power. Clouds of sulfuric acid lay above a layer of carbon dioxide near the crust. These sulfuric clouds block most Muggle attempts to see Venus. On Venus, the climate changes all the time, from an extremely cold temperature to an extremely hot one. The temperature ranges from -364 to 870 degrees Fahrenheit. Venus is the hottest planet in the Solar System, and yet it is Mercury that is the closest planet to the Sun, Venus being second in

be more than 90 times heavier than on planet Earth. Although Venus is not the closest

Scientists examined the Venusian atmosphere and found out that above the clouds the temperature is about 13oC, in contrast, at the surface of Venus the temperature gets as high as 465oC. It is believed that the principle cause of the extreme surface temperature is the consequence abundant carbon dioxide (CO2) in the atmosphere. Scientists concluded that Venusian atmosphere undergoes greenhouse effect. In essence, the heat delivered from the Sun enter the atmosphere and is radiated out, then again, it does not leave the atmosphere due to its heavy clouds that impede it from such. For this reason, Venus’ surface temperature is higher than that on Mercury – higher than any other planet! – leaving no chance of life.

Second, the author points out that there are no water and oxygen in the Venus atmosphere. The lecturer, on the contrary, thinks that the carbon dioxide and sulfur component of Venus atmosphere can be used to produce oxygen

The world renowned SETI institute (Search for Extraterrestrial Intelligence) has identified over a thousand extraterrestrial planets, and scores of which are sprinkled with oceans and lazily drift around in the Goldilocks zone, or the hypothetical distance a planet must be from its star to harbor temperatures that consistently keep its surface water in a liquid form. But even amidst these encouraging similarities with Earth, these seemingly habitable planets are usually half the size of our home world. The smaller the size of a planet, the less stable the barometric pressure and temperatures tend to be because the atmosphere does not permit the same amount of room for pressure and temperature inconsistencies to disperse, as Earth does. For example, astronomers theorize that Venus, Earth, and Mars were all potentially habitable planets during their

Humans have longed to believe in extrasolar planets, as surely there have to be planets elsewhere in the universe. Claims of supposedly discovered extrasolar planets can be dated back to 1855 when Captain S. W. Jacobs from the Madras observatory, claimed that he had discovered a planet orbiting a binary system (Jacobs 1855), all the way up until 1991 when a team of astronomers announced then retracted the alleged discovery of an extrasolar planet around a pulsar star (Lyne and Bailes 1992). Planets are extremely hard to detect as they are a very faint light source and the light from its parent star is much brighter and essentially blocks out light from a planet (Winters 1996). It was not until 1992 when the first exoplanets were confirmed

The main components of the Earth 's atmosphere is nitrogen and oxygen, the nine planets in the solar system composition is very special. Composition of the global atmosphere more of the ingredients can be divided into stable and unstable constituent components. The former include nitrogen, oxygen, argon, helium, krypton, methane, hydrogen, xenon, these gases the ratio between the height range from the surface to 90km are stable. Unstable atmospheric components include carbon dioxide, sulfur dioxide, ozone and water vapor and the like. In addition, the atmosphere also contains a number of solid and liquid impurities, mainly volcanic, seismic dust, rock weathering, forest fires and human activities, sulfide and nitrogen oxides.

The atmosphere of Venus made up of 98% carbon dioxide and 2% Nitrogen. This atmosphere also has the presence of helium, neon and argon. This is yet another thing which makes Venus different from Earth.

Venus and Earth are often called twin planets due to their similar sizes and locations, so Venus might seem like a reasonable interplanetary vacation spot. However, upon arrival, the “crushing ninety atmospheres” of surface pressure and “strongest greenhouse effect in the solar system” will render the trip a massive failure (Natural History). Despite their similarities, Earth and Venus differ greatly with regards to their atmospheres, making Earth a much more hospitable environment for human habitation. Even though Earth’s atmosphere does not receive nearly as much appreciation as its oceans or rivers, the layers of gas enveloping Earth are even more essential to the human race, making atmospheric destruction even more alarming.

Any factor that alters the amount of radiation received from the sun or heat lost to space may influence the climate. Therefore, any enhancement of the Greenhouse effect is a cause for concern. Besides fluctuations of solar radiation due to the earth orbiting around the sun, human activities influence the number of greenhouse gases.
