Planetary Comparison Essay

Man first came to live by finding shipway to sustain his lifetime. He could think, decide, create an opinion and work with his b are hands. by and by many old age of survival, he became more curious at the things roughly him. He saw the moon, the sun and the stars. It was when the man was curious that human life was considered intelligent life. With stunned mans curiosity, he wouldnt care roughly the orbiter that he is legionsing his life. Without his brain, he wouldnt know that opposite planets and former(a) heavenly bodies experience aside from the planet hide out.The properties of planet universe oerwhelm its systema skeletale, density, reflection of get out and age. The shape of the dry land resembles that of a sphere. It is a planetary planet because of gravity. What makes the reason spherical is the bulging characteristic it has on the equator. The bulges exist on this part of the planet because of rotation. Properties of the globe Density As of the Earth s density, it refers to the mass per unit volume of the planet. The density of the Earth drop be better imagined if compared to the density of iron, rock or pissing.The density of is 8 grams per cubic centimeter, 2. 5 grams per cubic centimeter for a rock. With urine, it is just a gram per cubic centimeter. Deep down the planet is surely a dense section of the Earth (Newman, 2000, p. 267). Reflection of Light An new(prenominal) proportion is reflection of light. The Earth has 37% albedo, which means that it has 37% of light that it is cap equal of reflecting. Again, to get the clearer picture, the reflection of light of the Earth shadower be compared to that of dirt, clouds and ice. diddley can except reflect around 10%, while water and clouds have just equal albedo. When albedo is moderate, it means that the reflection of light ranges from 40 to 60 percent. Meanwhile, ice has a high albedo because its reflection of light is just about a unshakable star hundred percent (Hamilton, 2001). Age of the Earth The age of the Earth is likewise an new(prenominal) airplane propeller of the planet. Planet Earth is as old as billions of years. With the help of radioactive dating of st nonpareils, scientists and geologists discovered that the Earth existed 3. to 4. 5 billion years past (Hamilton, 2001). The Earths Interior The Earths interior is characterized by explosions, earthquakes and seismic waves. there are waves that travel in both solid and liquid parts of the Earth. There are as well as waves that run only on solid ground (Hamilton, 2001). Inside the Earths interior, one can find nickel, iron and solid in the inner outcome. In the Earths outer center of attention are nickel, iron and liquid. Its chimneypiece are oxygen and silicon, which, when combined, form silicate rocks.The temperature inside the Earths core is hotter than the approach of the sun because of radio natural action and collisions. During the early years of history, the Eart h is form by numerous collisions and the heat from this activity contri notwithstandinged to the 6500K temperature of the planets core (Hamilton, 2001). Surface Changes It is a fact that the surface of the Earth changes constantly. One activity that contributes in the surface change of the planet is continental drift. Continental drift, as its name implies, refers to the drifting apart of the Earths continents.The continents move over time, and such movements were better understood and explained as the Plate Tectonics possible action came out, describing the lithosphere of the planet (Hamilton, 2001). If the lithosphere breaks, tectonic plates are built. In this planet, at that place are plenty of minor tectonic plates. With major tectonic plates, there are only seven. There is movement among these plates at contrasting kinds of boundaries which embroil transform boundaries, spreading or divergent boundaries and collision or focused boundaries.These boundaries pave way to the formation of oceanic trenches, mountains, volcanic activities and even earthquakes. create ment aloney two pieces of large lands collide (Hamilton, 2001). The tension caused by the collision alters the shape of the pieces of land. This is what happens to planet Earth. any(prenominal) type of activity there is, the surface of the Earth provide always be affected (Hamilton, 2001). Even erosion affects the surface of the Earth. Erosion happens when particles like rock, soil and sediments are displaced or moved to early(a) places.What cause the displacement are agents like water, living organisms and wind. Ice is also another cause of displacement because of the downward slope (Hamilton, 2001). The Earth and the former(a) Nine It cannot be denied that the Earth is special because compared to other planets in the solar system it is only the Earth that is capable of sustaining life. It has an atmosphere. It has displacement of lands. It has plate tectonics. It has water. It has humans . The one thing that separates the Earth from the other planets is the human being and human life.There may be signs of the existence of life in Mars, and that there are other forms of life in the moon of Saturn, but only Earth is capable of supporting and maintaining life (Moskowitz, 2008). Intelligent manner Even if it may be proven in the future that there are indeed organisms living in Mars, it is still safe to say that the Earth is shell to intelligent life. Other planets may be able to host life, but only the planet Earth is capable of hosting the intelligent kind (Moskowitz, 2008). Life on other planets would not even be possible without the planet Earth, according to Gregory Laughlin.Laughlin is a planet hunter and an astrophysicist at the prestigious University of California, Santa Cruz. Gregory was able to say this because the Earth delicately transferred some of its materials to the other planets. These tiny materials can be found in the planets crust (Moskowitz, 200 8). water system Another feature of the Earth which cannot be found in other planets is water. The planet is indeed a place conducive for evolution because it has water in it, in that amount. The amount of water on Earth is almost magical. The amount of water present in this planet is just overflowing to keep a desert alive.There is not too much(prenominal) water to drown the Earths mountains (Moskowitz, 2008). Water on Earth is different from the water in the other planets because the water in the other planets either fry or freeze. This can be explained through and through the remoteness between the planet earth and the sun (Moskowitz, 2008). Distance Distance, of course, is a unmatched feature of the planet. The Earth indeed has the best location in the solar system because if we depend on too much sun, therefore the blank space between the planet and then sun is just right enough to match the Earths geological timescales (Moskowitz, 2008).It is the temperature we get fro m the sun that regulates the Earths atmosphere. It is the distance between the Earth and the sun that keeps the temperature of the Earths surface around the temperature of the waters (Moskowitz, 2008). Size The size of the Earth is also another unique feature of the planet. A smaller Earth will not leave space for the planet to hold on to the atmosphere. A bigger Earth may be a hotter Earth for humans. Hotter in this sense means the kind of warmness which humans will not be able to tolerate (Moskowitz, 2008). Getting More Detailedhydrargyrum is the nearest planet to the Sun. Among all the other planets, it is the eighth largest. It has two moons to wit Titan and Ganymede. While these moons are smaller than Mercury, they are more colossal than the planet. Mercury, compared to the Earth, is immediate to the sun (Arnett, 2008). Venus, on the other hand, is the sixth largest planet in the solar system. It is also nearer to the sun compared to the Earth. It is an inferior planet with phases easily seen through a telescope from the Earth (Arnett, 2008). Aside from the Earth, Mars stands out to be a popular planet since the early times.Today, there are observatories that are ground-based just to study Mars. The size of Mars is a obstacle in studying it, but the planet still shows features that can host life (Arnett, 2008). The biggest planet in the solar system is Jupiter. When it comes to mass, this planet is double massive compared to the Earth and to the other planets as well. In fact, when compared to the Earths mass, Jupiter has 318 times more (Arnett, 2008). Saturn is a popular planet since the prehistoric years because there was Galileo in 1610, holding a telescope, observing this planet with rings.Galileo knew that Saturn looked different and he thought that the Earth passes through the rings after some years on a regular basis (Arnett, 2008). If the Earth is spherical, then the planet Uranus is ecliptic. Unlike the Earth, Uranus poles are hotter than i ts equator. The poles of this planet are more overt to the suns energy than the equator (Arnett, 2008). Neptune is far from the sun, but its core measures the said(prenominal) as that of the mass of the Earth. Its core is made of rocks. It does not have a unique internal layering like that of Saturn and Jupiter, but the composition is nonetheless distinct.Whatever heat it receives from the sun is nothing compared to the heat it can generate itself through its core (Arnett, 2008). Pluto is the smallest planet in the solar system. It has an eccentric orbit, which makes it closer to the sun at times than Neptune. Unlike the Earth and all the other planets, this heavenly body rotates in the opposite direction (Arnett, 2008). Above all these, it is still the Earth that stands out. All these pieces of information would not be cognize without the human mind, made possible with life, sustained by the Earth.
