The first planet after the Sun, Mercury, has very similar geological features with the Earth's moon. Its surface is covered with varying sizes of craters which was used by scientists to determine the planet's age. It is said that these craters are the "scars" from asteroid and comets during the Late Heavy Bombardment Period. Measuring 1550km, the Caloris Basin is the largest crater in Mercury's surface and 14 other large crater basins were found. Although it has been identified that Mercury's surface is geologically inactive, large deposits of water ice can be found near its poles. These bodies of water ice were found on deep craters around Mercury's poles and are always in the shadows. If one side of the planet is covered with craters, another …show more content…
It is also the brightest in the sky next to the Sun and the moon. This brightness of Venus is caused by the thick clouds of sulfuric acid that reflect sunlight back into space. Runaway greenhouse gases is responsible for the large amounts of carbon dioxide in Venus' atmosphere. Its atmosphere also includes 3.5% of nitrogen and less than 1% of carbon monoxide, argon, sulfur dioxide and water vapor, leaving 96% of its atmosphere with carbon dioxide. The greenhouse effect on this planet is also responsible for Venus being the hottest planet in the Solar System. This extremely dense atmosphere is equivalent to the pressure one would experience when diving 3000ft beneath the ocean and Earth-like atmosphere can be experienced 50-60km above the surface of Venus. Significant temperature changes were not recorded in Venus, thus, day and night temperatures do not differ. This is true for seasonal changes as …show more content…
The breaking apart of this supercontinent was due to the movement of the Earth's Tectonic Plates. Tectonic Plates are large masses of the lithosphere or outer layer of the Earth's surface. The layers included in the Lithosphere are the Crust up to the upper layer of the Mantle. The Oceanic Crust is thinner and denser than the Continental Crust and can be found underneath the ocean. It is also more active than the Continental Crust that stretches 200 km below the Earth's surface. This crust drifts and moves either horizontally or vertically causing geological phenomenons such as earthquakes, volcanic eruptions, etc. The major tectonic plates are North American, Caribbean, South American, Scotia, Antarctic, Eurasian, Arabian, African, Indian, Philippine, Australian, Pacific, Juan de Fuca, Cocos, and Nazca. These plates move an estimate of 1 to 10 cm per year causing interaction at plate boundaries. When two plates are colliding or moving toward each other it is in Convergent boundaries. If these two plates are Oceanic Crusts, they are in Subduction zones wherein the denser plate in forced beneath the less dense plate and would eventually melt or destroy. On the other hand, when two plates move away from each other it is in Divergent boundaries. New crust material from molten magma formed below may fill the space between these plates or become ocean basins.
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
Two plates can separate to split continents apart, to form new oceans, or to enlarge existing oceans by forming new crust in giant rifts in the ocean floor. Plates can converge and collide, forming chains of volcanic islands and deep trenches in the ocean, volcanic mountain belts along coasts, or giant belts of folded mountains between continental masses. These movements and their physical consequences are studied in the branch of geology called plate
It also includes small amounts of other gases, such as carbon monoxide, argon, neon, and helium. The atmospheric pressure on Venus is over 90 times heavier than that on Earth. Over a thick layer of carbon dioxide closest to the surface are layers of clouds of sulfuric acid, which have obstructed Muggle attempts to observe Venus closely. Venus is the hottest planet in our solar system, and this is due to the effect of runaway greenhouse gases, which left a permanent mark on the planet’s climate. Venus’s temperature ranges from -364 to 870 degrees Fahrenheit. Venus is one of the brightest planets in the sky, and this is due in part to its clouds, which are highly
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
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 planet's atmosphere is also surrounded by thick, acidic, sulfuric clouds. The atmospheric pressure is approximately 90 times that of Earth, and the atmosphere is made up mainly of carbon dioxide, with the remaining 3.5% taken up with nitrogen and a few other elements. The thick sulfuric clouds surrounding the planet make it difficult to view the surface with any accuracy, and the huge pressure and heat below the clouds mean that the atmosphere is not conducive for human-made crafts to survive in the climate. Venus's atmosphere is in constant circulation of the planet, circling it in a mere 4 Earth days. The winds near the atmosphere of Venus are approximately 220mph in order to facilitate this speedy atmospheric rotation, although the winds on the surface are much much slower. In summary, Venus would be a bad (and unpleasant) choice for human habitation, due to enormous levels of atmospheric pressure, very high temperatures, and sulfuric acid
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
The thicker sections fo the plates are the continents; the thinner parts make up the ocean beds. When two plates meet, the result is geologic upheaval on a vast scale. Such an encounter occurred about 20 million years ago in the region between North and South America. The Cocos Plate, a piece of the Pacific crust some 300 miles wide, moved eastward until it met the crustal plate underlying the Caribbean. The eastern edge of the Cocos Plate was driven beneath the western edge of the Caribbean Plate. As the Cocos Plate was forced downward, the friction, as well as the hear deep within the earth, liquefied its rock into magma, which found release by thrusting up in a chain of volcanoes. The volcanic islands that resulted formed a line of stepping-stones between the northern and southern
Wow! She wasn’t kidding! I count about 54 craters before I lose count, and I am sure I can only see a fraction of its surface. Since Mercury doesn’t have much of an Atmosphere, it is a frequent target to meteors. Muggle scientists believe that there might even be ice in some craters…
Venus' atmosphere and climate has been studied carefully as it is believed this is what our atmosphere may come to be in the future. With an atmosphere made up of approximately 96.5% carbon dioxide and 3.5% nitrogen it has an astonishing atmospheric pressure of about 1352 pounds per square inch - which is approximately 90 times that of Earths.
. The two inner planets Mercury and Venus moves from east to west along the ecliptic between their time of greatest distance from the Sun to the east as an evening star and their greatest elongation west as a morning star.
Some nitrogen and clouds of sulfuric acid are also their. The air of Venus is so dense that the nitrogen is four time the amount on Earth. This composition causes a runaway greenhouse effect that heats the planet even hotter than the surface of Mercury, although Venus is farther from the sun. In addition to warming the planet, the heavy clouds shield it, preventing observations of thesurface and protecting it. Winds of about 224 mph keep the clouds of Venus in constant motion. Though the planet spins slowly, only once every 243 Earth days, the clouds zip around the top of the planet every four days. But wind speeds drop closer to the surface, where they only move a few miles per
Adjacent plates pull apart, such as at the Mid-Atlantic Ridge, which separates the North and South America Pates from the Eurasia and Africa Plates. This pulling apart causes "seafloor spreading" as new material from the underlying less rigid layer, or "asthenosphere," fills the cracks and adds to these oceanic plates.
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.
Venus is the 2nd planet from the Sun. Venus' reflective nature and close proximity to Earth are major factors in it's being one of the brightest objects in the sky after the Sun and Earth's moon. It is often referred to as
