A Complete Explanation of Land/Earth Tides

Land tides, also called Earth tides, are very small deformations or movements in the Earths lithosphere (surface) caused by the gravitational fields of the sun and moon as the Earth rotates within their fields. Land tides are similar to ocean tides in how they are formed but they have very different impacts on the physical environment. Unlike ocean tides, land tides only change the Earths surface by around 12 inches (30 cm) or so twice a day. The movements caused by land tides are so small that most people are not even aware that they exist. They are very important to scientists like volcanologists and geologists however because it is believed that these small movements may be able to trigger volcanic eruptions. Causes of Land Tides Like ocean tides, the moon has the greatest effect on land tides because it is closer to the Earth than the sun. The sun does have an effect on land tides as well because of its very large size and strong gravitational field. As the Earth rotates around the sun and the moon each of their gravitational fields pull on the Earth. Because of this pull there are small deformations or bulges on the Earths surface or land tides. These bulges face the moon and the sun as the Earth rotates. Like ocean tides where water rises in some areas and it is also forced down in others, the same is true of land tides. Land tides are small though and the actual movement of the Earths surface is usually no greater than 12 inches (30 cm). Monitoring Land Tides Due to these cycles, it is relatively easy for scientists to monitor land tides. Geologists monitor the tides with seismometers, tiltmeters, and strainmeters. All of these instruments are tools that measure the motion of the ground but tiltmeters and strainmeters are capable of measuring slow ground movements. The measurements taken by these instruments are then transferred to a graph where scientists can view the distortion of the Earth. These graphs often look like undulating curves or bulges indicating the upward and downward movement of land tides. The Oklahoma Geological Surveys website provides an example of graphs created with measurements from a seismometer for an area near Leonard, Oklahoma. The graphs show smooth undulations indicating small distortions in the Earths surface. Like ocean tides, the largest distortions for land tides appears to be when there is a new or full moon because this is when the sun and moon are aligned and the lunar and solar distortions combine. Importance of Land Tides In addition to using land tides to test their equipment, scientists are interested in studying their effect on volcanic eruptions and earthquakes. They have found that although the forces causing land tides and the deformations in the Earths surface are very small they do have the power to trigger geologic events because they are causing changes in the Earths surface. Scientists have not yet found any correlations between land tides and earthquakes but they have found a relationship between the tides and volcanic eruptions because of the movement of magma or molten rock inside volcanoes (USGS).

The Role Of Religion On The Growth Of The Ancient...

The Role of Religion What role did religion play in the growth of the Ancient civilizations? Religion can invade, conquer, and rule masses of people far more effectively and efficiently than any empire or conqueror. This is not to spark a heated discussion about religions. Its purpose is, to say that, even though it is highly debatable whether religions are false or true, most of them serve a very basic purpose of establishing morals and values. Early religions were used as a source of power and economic growth. Even if one doesn’t believe in or agree with the teachings of any religion, history shows proof that it creates a sense of order. There are many religions in the past that have brought order and civilized conduct to large numbers of people, not through military conquest, but through the promise of reward or the fear of punishment. Religion is the glue that binds local communities into nationhood and creates common understandings and shared values that are essential to the growth of a civilization. No religion is fully formed at its start, so why did some reli gion play such a big role in growth of the Ancient Civilizations. The rise, development, and spread of monotheism (the belief in one God), is one of the most significant and fascinating dimensions of human civilization.

In the heroic poem of Gilgamesh the Gods decided to destruct world by deluging Earth for six yearss and darks. Utnapishtim was chosen to construct a boat in order to re-start world after the inundation. In The Bible, God decided that there was excessively much immorality in the universe and decided to deluge Earth for 40 yearss and darks. God Chose Noah to construct an Ark to salvage 2 of each animate being and restart world after the inundation. In both The Epic of Gilgamesh, and the Bible, a narrative of a great inundation occurs these narratives compare and contrast in several important ways. We will write a custom essay sample on The Epic Of Gilgamesh And The Bible or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page In both narratives world was exterminated because things were acquiring to helter-skelter. In Gilgamesh the God Enlil # 8217 ; s ground for desiring to destruct adult male was # 8220 ; the tumult of world is unbearable and sleep is no longer possible # 8221 ; The other Gods agreed with this. In the Bible, God besides saw how the evil of adult male had taken over earth.Utnapishtim was chosen to last the great inundation because he was a true worshipper of the god Ea, who came to warn Utnapishtim about the flood. Noah was the only man on earth who found grace in the eyes of God, and was really good. Because of this, God came to warn him about the flood and told him to build the ark. They each approached their Journey by building a large boat, and bringing his family and two of every flesh being onto the boat. Utnapishtim’s boat was two hundred feet tall, with six stories. Noah’s ark was thirty cubits high, and three stories. They each survived by staying in the boat during the whole flood, until it was over. From the god Ea, Utnapishtim was rewarded life eternal. Noah was blessed by God and was rewarded all earth’s flesh as meat for him and his family. The differences between Hebrew and Babylonian cultures that these stories suggest is that what people want as a reward is different. In Babylon culture, immortality is considered a gift. In Hebrew culture, rewards of food and blessings i s what Noah wanted. If I had to Choose between being Noah, or Utnapishtim, I would be tempted to have eternal life, like Utnapishtim, but I would probably choose to be Noah, because I would be blessed. Also, Noah is more recognized today than Utnapishtim.
