The Origin Of Water On Earth Essay

The science that is connected with planet earth encompasses geosciences or earth science among others. Containing old histories, this is considered as a part of planetary science while it possesses holistic and reductionist approaches in the science of the planet Earth. This discipline can cope with lithosphere, atmosphere, biosphere or hydrosphere. Quantitative understanding has been developed by the scientists to understand the ground systems with the tools by mathematics, physics, chronology, biology, chemistry alike that help to know how the universe is evolved.

water covers more than 70 percent of the planet's surface, making our rivers, lakes, oceans,

fresh water found on planet earth is only a mere one percent (1%) and we have to bear in mind that within that one percent some are found in lakes, rivers, streams and underground aquifers.

Around the world our water supply is depleting. Our water is becoming contaminated making it harmful for both mammals and aquatic life. Today over one billion people go without adequate water supply and every fifteen seconds a child dies of waterborne illness. Sources of water that once supplied water to millions can no longer meet the supply and demand of the water need. Scientist predict that the amount of useful water will keep depleting greatly in the years to come. In the next couple of pages it will talk about both the geological and human reasons as to why are water supply is depleting.

The earth is like a living organism; it thrives full of life with a fragile balance. This balance has been thrown off by many different things. Water seems to be one of the biggest problems with this offset balance. Water is a magic liquid keeping all of life thriving. Humans drink and use water, plants use water, water is used in everyday life, and it’s slowly being taken away. In the future, there will be no water left to sustain life on earth.

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

The water cycle of the Earth is in constant balance, evaporating water from the oceans and other bodies of water, and depositing it on land through snowfall and rainfall, before ultimately returning it to the oceans via vast river networks. An amazing fact of the water cycle is how much water for the cycle is stored in the ocean phase, 96.5%, leaving a small amount available for deposition and runoff (United States Geological Survey, 2014).

Water has been around for almost as long the Earth has been around, approximately 4.6 billion years ago. In some shape or form, water has continued to be an important resource since the formation of Earth and continues to be today as well. Water being a finite abundant substance, it covers up approximately 70 percent of the Earth’s surface. It is without a doubt an essential resource needed to sustain life on Earth. Nonetheless, not only is water an important resource for all living organisms for subsistence, but it also serves other purposes: agriculture purposes, medical and health purposes, tourism and much more. However, with the recent emergence of the issue surrounding

Water is essential for life as we know it on earth. It is used by plants

Earth is a perfect distance from the sun so the temperature of the Earth is the right tempeture for water.

The Importance Of Water To Living Organisms Water is normally the most abundant component of any living organism. As most human cells are approximately 80% water and 60% of the human body is made up of it, it is extremely important in many different ways to both the survival and the well being of living organisms. Evolutionists believe that life probably originated in water and even today thousands of organisms make their home in it. Water also provides the medium in which all biochemical reactions take place. The importance of water to living organisms originates from its many properties including its solvent properties, its high specific heat capacity, its high latent heat of vaporization,

Water is a substance that is in great abundance on this planet and life almost certainly originated from it. It is required for multiple purposes and explains several day-to-day mechanisms (Chemical Elements and Water, 2007). The biological significance of water in the human body alone is 70% therefore demonstrates how crucial it is.

Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard. This region is thought to be one of the droughtiest places in the world, most of it’s territory is deserted. Freshwater accounts to 1 percent of the world’s supplies, while the population comes

Water is the lifeblood of every living creature on earth. Approximately 70 percent of the earth's surface is covered with water. Thought the wonders of nature, water can take on many different forms, form the water we drink, to the ice we use to chill a glass of lemonade, to the water vapor used to steam clean equipment equipment. It is easy to understand the significance water plays in our lives, but it may be much more difficult ot understand the water that exists below the earth's surface, called groundwater.
