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
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
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's atmosphere is made up of carbon dioxide. Nitrogen and clouds of sulfuric acid are also there. Nitrogen makes up three fourths of the atmosphere. This causes a greenhouse gas effect that heats the planet, making it even hotter than Mercury. Venus's clouds also shield the planet. Venus has wind speeds of up to 224 mph, keeping Venus's clouds in constant motion. The planet spins very slowly, only once every 243 Earth days, but the clouds circle the planet every four days. On Venus the sun's light rays usually fail to get through Venus's thick atmosphere. That means that Venus's temperature changes a lot from night to day. Venus's clouds appear to be white or yellow. That is why Venus's atmosphere and climate is the way it
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
The atmosphere also contains traces of carbon monoxide, argon, helium and neon. The closest layer to the surface of Venus is a thick layer of carbon dioxide, which is much denser and hotter than that of Earth. There is early evidence that sulphuric acid also lay within the atmosphere of Venus, as another layer within those that surround Venus is consisted of sulphuric acid. The atmosphere of Venus circles the celestial body in just four day due to its “super rotation” and “vigorous circulation”. Venus is the hottest planet in our Solar System even though it is further from the Sun than Mercury though, it used to have a climate much like Earths but runaway greenhouse gasses have affected the
The atmosphere is so dense that it is the equivalent of being under the sea at about half a mile. Venus also has one of the strongest greenhouse effect of any planet in the solar system due to the large presence of carbon dioxide and sulfur dioxide. Venus' suface is then hotter than Mercury's surface. There is not much variation of the temperature on Venus depending on day and night because there is thermal inertia. Another contributing factor to the climate is that winds are very low. The clouds are also capable of producing lightning. There also is an ozone layer in the atmosphere of
I force my fingers, numb from the cold, to work, as I finish assembling Professor Polgara’s new Scope 72, a fantastic black and golden telescope. She lent it to me with the promise of it being returned in absolute perfect condition, and accompanied by a report on my observations. My assignment for this morning: the elusive planet Mercury.
Planet surface conditions: Mercury’s surface is similar to our moons. Its surface is littered with deep craters. 3.8 billion years ago was overwhelmed by a huge amount of craters and was believed that the surface was volcanically active.
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
The atmospheric pressure is substantially more than that of Earth, totaling up to more than 90 times heavier than Earth’s. Closest to the surface of this planet is carbon dioxide, trapped in a thick layer against the surface. Over this layer are clouds of sulfuric acid, that reflect over 90% of the sunlight that hits the planet, and makes it very difficult for muggles to capture images of the surface. It is definitely one of the brightest objects in our night sky. The climate of this planet is a very heated one. It is the hottest planet in the Milky Way, even though Mercury is much closer to the Sun. One theory states that Venus, at one point, had a climate similar to that of Earth, but greenhouse gas effects impacted the climate permanently. Like Mercury, the temperature of this planet fluctuates greatly, going from -364 to 870 degrees
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
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.
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
pics snapped by means of a NASA spacecraft have furnished the primary complete photo of ways the single rocky plate that encapsulates Mercury is contracting, warping the surface into puckered ridges and scallop-edged cliffs known as lobate scarps."it's far Mercury's model of a mountain belt," Paul Byrne, a planetary geologist at the Carnegie institution in Washington, D.C., and lead author of the have a look at in Nature Geoscience.
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.
