It is believed that only 55% of Mercury has been mapped, however, that 55% has yielded a number of interesting finds, there are three significant geological features on Mercury, these are: smooth plains, intercrater plains and rugged highlands. The smooth plains resemble Lunar Maria, that is, large dark basaltic plains formed by ancient volcanic eruption, found on the Earth’s moon. The Intercrater Plains are impact craters, pocked with a number of smaller craters, which cover 70% of the examined surface. These craters are particularly deep, due to the planets lack of an atmosphere to slow the bodies before impact. The rugged highlands resemble mountainous regions of the Earth; however, there is no evidence of tectonic motions to have caused them. Mercury is made up of predominately iron, its crust is only 500-600km thick and there is evidence of volcanic activity, although it is believed that the planet has been geologically dormant for billions of years. The atmosphere on Venus is composed of mostly Carbon dioxide with small amounts of nitrogen and sulphuric acid. This composition causes a runaway greenhouse gas effect that makes the planet even hotter than Mercury, despite the fact that Mercury is much closer to the sun. The air on Venus is incredibly dense due to the Nitrogen content, which, whilst admittedly is only a small part of the atmospheric composition, is at least four times the amount on Earth. This Atmospheric composition therefore creates a thick layer of
There are characteristics of Mercury that make it an appropriate target, and some that make it not. The different characteristics presented in the case are as follows:
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
Venus has an atmosphere of about 96.5 percent carbon dioxide. Nitrogen is present at around 3.5%. Argon, neon, helium and carbon monoxide are also present, as well as other compounds and elements. Because of this, the atmosphere of Venus has an atmospheric pressure that is much heavier than that of earth--over 90 times heavier. The atmospheric closest to the surface of the
Mercury is a heavy, silver-white, highly toxic metallic element. It is the only metallic element that is liquid at room temperature. Mercury can be used in thermometers, pesticides, pharmaceutical preparations, surfaces of mirrors, and dental fillings. There are several forms of mercury which include elemental or metallic mercury, inorganic mercury compounds, and organic mercury compounds. Elemental/metallic mercury is liquid at room temperature and turns into a colorless, odorless gas when heated. (Mercury: Basic Information, 2014)
Summary: (about 5 sentences) Mercury was one day old when he start walking and invented the lyre with an empty turtle shell. Also, still as a day old baby he stole two cattle from Apollo while he was asleep, because he was so hungry. Apollo realized afterward that Mercury was the one that stole his cattle’s, and went to his house to talk to him. Mercury felt bad of what he did, and gave the lyre to Apollo, this gesture made him so happy that he gave to Mercury a gift, a magic wand that has power to stop fighting.
There are a few other reasons why Venus cannot sustain human life. One of them is because of a huge cloud that surrounds Venus. This cloud is made up of corrosive acid, which is due to the sulfur from volcanic eruptions on Venus. The second reason is because the atmosphere pressure on Venus is also ninety times stronger than it is on earth, which is strong enough to crush a car. The third and final reason we would not be able to live on Venus is because the atmosphere of Venus is nearly all Carbon Dioxide, which makes the temperatures over nine hundred degrees Fahrenheit.

Venus named after the Greek goddess of beauty and love and the sister planet of Earth, has an interesting atmosphere and climate. Venus consists of 96.5% of carbon dioxide and 3.5% of nitrogen. Although there has been traces of other elements and compounds such as carbon monoxide, argon, helium and neon. The composition of Venus makes the atmospheric pressure more than 90 times heavier than Earth! The surface closest to Venus is a thick layer of carbon dioxide. Over the layer of the thick carbon dioxide, unearths layers of clouds filled of sulfuric acid which reflect 90% of the sunlight that hits Venus. Venus is one of the brightest objects in our sky. Venus is the brightest planet in the solar system. A theory of Venus, is that once it was a lot like Earth. The temperatures on Venus range from, -364 to 870 degrees
In the passage presented the author looks into the problem of declining readership of The Mercury, a weekly newspaper, and recommends actions to boost its circulation. However, the argument is riddled with logical flaws because it fails to analyse the causes of the problem deep enough and fails to take into account possible unintended consequences of suggested actions.
Due to runaway greenhouse effect that irrevocably changed the conditions on Venus, the climate of the planet can be called truly hellish: the temperature on Venus can go up to 870 degrees Fahrenheit and the pressure equals that of about a kilometer under Earth’s oceans. Thick sulfuric clouds downpour constant acid rains on the surface that are immediately evaporated. The winds at the surface are slow but they are carrying around considerable amount of dust and rocks. However the atmosphere of Venus is layered and at about 50-65 km above the surface the temperature, pressure and the atmosphere composition closely resembles that of the Earth and is practically “habitable”. That makes it a possible place for exploration and maybe even
It is curious discoveries and predictions we make about the contents in our solar system. Mercury’s, the smallest planet, core has been studied and theorized about. When it comes to density and size, “geologists estimate that Mercury's core occupies about 42% of its volume, compared to Earth's 17%.” (https://phys.org/news/2015-08-planet-mercury.html (Links to an external site.)Links to an external site.). The theory most widely assumed is that “was once a larger planet … struck by a planetesimal measuring several thousand km in diameter. This impact could have then stripped away much of the original crust and mantle, leaving behind the core as a major component.” Planetesimals are dust, rock and other space matter: regarding its most impactful
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.
Mercury is an element of the earth, and can take place naturally as well from manmade. Mercury continuously comes up towards the surface of the earth’s crust, because of the high temperature of the earth’s mantle, and this can make mercury a very mobile source. Surface rocks can contain high levels of concentrated mercury, which can add to the levels of emission standards of mercury. Natural sources can come from the earth crust, volcanoes, and erosion. Others are from weather, floods, and forest fires. This type of contamination is beyond mans control, and must be considered part of our atmosphere mercury levels. Scientist to this day have been struggling to separate the two from mans involvement to the natural output of mercury. Other
Mercury, named after the Roman God of Thievery, Commerce, and Travel, is the first planet from the Sun. It is unique because it shows at both morning rise and evening set of the sun. It is rocky, heavily cratered, covered in boulders, and also pulverized dust. The majority of it's surface bears a strong resemblance to that of Earth's moon. It's lack of atmosphere causes wild temperature fluctuations. Temperatures can range from 90 kelvin to 700 kelvin thus creating a planet, from all observations, that cannot sustain life--it is geologically dead. Mercury also has a magnetic field generated by the planet's core that can deflect solar wind and which has a magnetosphere that changes. This was surprising for such a slow rotating planet--one that rotates completely every 88 Earth days.
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.
