Evidence for (or against) water on Mars Research Paper

Evidence for (or against) water on Mars - Research Paper Example Scientists pondered the possibility of life on the red planet, while artists and dreamers such as H.G. Wells took the notion even further, imagining a Martian conquest of Earth in his 1898 book "War of the Worlds."† (Doydey and Lamb). Some astronomers argue that water exists on mars planet in the form of water ice. Many scientists claim that Mars contains water because it supports life of all forms. The Mars volcanic activities that lead to freezing and melting of ice can be another example of underground water existence. Polar ice caps can exemplify water existence on Mars because of carbon dioxide ice. Therefore, volcanic activities, the existence of polar ice caps and presence of chemical compounds on the Martian surface rocks confirm water in the Mars planet. Notwithstanding that there were hundreds of investigation held, the issue is still controversial and needs further research. However, this research can be implemented only with the help of further technological achieve ments. The planet Mars consists of water in the form of ice. Mars planet has two polar ice caps, which are constant. The Martian pole in winter is in constant darkness and the surface is chilled. This contributes to approximately 30 percent of the atmosphere, which is in the form of carbon dioxide ice (dry ice).... Dowdey and Lamb agree with his â€Å"Mars is replete with water, but most (if not all) of it is in frozen or vapor form. For instance, ice caps the planet's poles, and patches of ice lie over dunes in craters† (Dowdey and Lamb).The Martian surface rocks occur in high latitude areas, which are known as permafrost, which is in a freezing state below the 0 °C. Most permafrost areas are located in high latitudes, and ice is not always present, but they occur due to hydraulic saturation of the bedrock materials. Water vapor is always presented in the atmosphere but the permafrost is lacking of liquid water. The present condition of the surface of many planets does no longer support the existence of water in liquid form for a longer period. This is because the atmospheric temperature is too low. In this case immediate freezing and sublimation processes occur. The research study indicates that the liquid water exists in liquid water flow on the earth’s surfaces thus creating larger surface areas for oceans or seas. There are varied proofs about the presence of water in Mars. With increased technology, the scientists are now able to use advanced cameras of Mars orbiters including the mars odyssey, global mass surveyor and reconnaissance orbiters for visual confirmation of the presence of water in the mars planet. With the help of different technical tools modern scientists are very much focused on possible effective ways of water finding on Mars. Quality of water is another important issue for their concern. Further on we will focus on different theories and hypotheses about water existence on Mars planet. NASA's  charge  to  researchers  on  the  mission  has  been  simple:  Ã¢â‚¬Å"Follow the water," meaning examine all aspects of water-or ice on Mars. No water

Economy and Socal Life in Kenya Assignment Example | Topics and Well Written Essays - 1000 words

Economy and Socal Life in Kenya - Assignment Example Kenya has made progress towards enhancing effectiveness in the political system with the implementation of a new constitution. Kenya has a population of 44 million with most people living in the rural areas. The capital city is Nairobi. It is also the hub for many government services. The other major towns and cities in Kenya are Nakuru, Mombasa, and Kisumu. Kenya is bordered by countries like Uganda, South Sudan, Tanzania, Ethiopia, and Somalia. The two main languages in Kenya are Swahili and English. It provides information on the people, infrastructure, education, security, and transport. Kenya is made of 42 tribes that are spread out in different parts of the country. The notable ethnic groups in Kenya are Kikuyu, Luo, Luhya Kalenjin, Kamba, Kisii, and Meru. The chart shows ethnic group distribution according to the data presented by the CIA World Factbook. The major religions in Kenya are Christianity and Islam. Majority of Kenyans fall between 25 and 54 years. The majority of Kenyans are young. The country struggles with high infant mortality rates, HIV/AIDS, famine, and floods. According to the CIA World Factbook, Kenya ranks 31 when compared to other nations in the world. It is clear from the graph that Kenya has many non-Africans who are citizens and foreigners. The country has expatriates who work with large business corporations or non-governmental organizations that deal with environmental issues, aid, and relief and activities. Most of the expatriates live in highly secured estates. The estates have secured houses with compounds to limit movement in and out. The diverse nature of the Kenyan population makes it easy for foreigners to fit in. The culture can be termed as friendly with most people believing in the concept of African hospitality. Kenyans find it easy to help foreigners.
