Mercury is like a large rock. Its surface geology is quite similar to Earth's moon. It has many craters from ancient impacts, and also basins and plains. Some of the craters have filled with lava from the planet's interior, and have become lava plains as a result. Boulders and dust from pulverized rock are found on the surface. There are no rivers. The Mariner 10 and Messenger missions sent back many pictures of Mercury's surface, so we know that there is no weather there to affect the surface. From a geological standpoint, Mercury is identified as a planet that has been long dead. Even though it has not been completely mapped by cameras, scientists studying Mercury believe that its surface has not changed for billions of years.
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

These plates, along with several smaller ones, are called the lithospheric plates, because they are part of the lithosphere, which is the outermost part of the Earth's shell. . The plate boundaries can be three different types: divergent, transform or subduction. Divergent boundaries occur when the plates are moving away from each other. Transform boundaries are where the plates slide against each other with a back and forth motion. Subduction boundaries occur when an oceanic plate moves under a continental plate. This movement causes volcanic activity and earthquakes. (This boundary is also called convergent.) This activity is always happening, because the plates are constantly in
There are three different types of plate boundaries. The first type of plate boundaries is, the spreading boundary. A spreading boundary is when two plates move apart. The spreading boundary is also known as a divergent boundary. The second type of plate boundary is a colliding boundary. A colliding boundary is when two plates come together, or collide. It is also known as convergent boundary. The third is, a sliding boundary. A sliding boundary is when two plates slip past each other moving in opposite directions. It is also known as transform boundary. Those were the three different types of plate
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
Earth is the only known planet in our solar system that can/does sustain life. About 200 million years ago, each continent formed a super-continent called "Pangea". Pangea split due to the movement of Earth's tectonic plates. "Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle. This strong outer layer is called the Lithosphere.". Convergent boundaries are one of the three types of plate boundaries that occur on Earth. The other two are: divergent and transform margins. During a divergent margin, two plates are spreading apart. Transform margins show the grinding of two plate in a mostly horizontal motion. One example is the San Andreas Fault Line, where the North America and Pacific plates grind past each other in a horizontal fashion. The major plates are: North American Plate, South American Plate, Pacific Plate, African Plate, and the Eurasian Plate. "Lithospheric plates are regions of Earth's crust and upper mantle that are fractured into plates that move across a deeper plasticine mantle. Earth's crust is fractured into 13 major and approximately 20 total lithospheric plates. Each lithospheric plate is composed of a layer of oceanic crust or continental crust superficial to an outer layer of the mantle. Containing both crust and the upper region of the mantle, lithospheric plates are generally considered to be approximately 60 mi (100 km) thick. Although containing only continental crust or oceanic crust in any one cross-section, lithospheric plates may contain various sections that exclusively contain either oceanic crust or continental crust and therefore lithospheric plates may contain various combinations of oceanic and continental crust. Lithospheric plates move on top of the asthenoshpere (the outer plastically deforming region of
There are three distinct types of plate boundaries existing, which are supported by geological observation, geophysical data, and theoretical considerations. Their names and categories are based on if adjacent plates move apart from each other (divergent plate margins), toward one another (convergent plate margins), or slip past one another in a direction parallel to their common boundary (transform plate margins) (Pitman, W.C., 2007).
The theory of plate tectonics states that Earth’s outer shell is divided into plates. The crust and upper mantle is broken into plates that move around on the mantle, changing in size throughout time. The lithosphere makes up the crust and upper mantle and the asthenosphere a plastic like layer beneath the lithosphere. There are three types of plate boundaries. Divergent boundaries where two plates move away from each other. The ocean widens and new crust forms at the mid-oceanic ridge. Convergent boundaries has three types of converging, moving two plates towards each other. First we have an ocean floor plate that collides with a less dense continental plate. Next an ocean floor plate collides with another ocean floor plate. Finally a continental plate collides with another continental plate. Transform boundaries were two plates slide past one another. The resulting effects of plate tectonics is landforms such as rift valleys,
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
Mercury is the closes to the sun and Venus is 2nd close to the sun. Mercury and Venus are inter planets that means they are two of the 4 inter planets. They are not made of gas that is only the outer planets are the only ones that can be made of gas. Venus earth's closest neighbor in the solar system. Venus is the brightest object in the sky after the Sun and the Moon, and sometimes looks like a bright star in the morning or evening sky but I have never seen it before. Mercury is named for the ancient Roman god of trade and profit the roman people believed in many
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.
The three major types of tectonic plates are divergent, subduction and transform. Divergent plates tend to move apart from each other. Subduction plates are when oceanic plate moves under a continental plate. This can cause volcanos to erupt and large sized earthquakes. Transform plates slide back and forth against one another. The Lithosphere consists of the Earths crust and uppermost mantle. The North American plate and the South American plate are the major plates of the lithosphere. The lithosphere also consists of the Pacific plate, the African plate and the Eurasian plate. The Pacific plate is the only major plate that is mainly underwater and is also the largest plate in the lithosphere. The Earth was once one large continental body called Pangea, before the plates started
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
Finally, this leads to the idea of Venus having very thick and dense clouds hence heavy atmosphere composed of 96.5% of carbon dioxide (CO2) and 3.5% of Nitrogen (N2).
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 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
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.
