The Movement And Distribution Of Water On Earth

Apart from the article by Barnett, several other papers have been written concerning water crisis. For instance, the American Water Works Association writes that in as much as the world is covered with 70% water, 97% of it is salty, and therefore it is not suitable for consumption. Another 2% is ice that is found at the poles. Primarily, this cannot be accessed for consumption since it is far from habitable places. Only 1% is available for use (American Water Works Association).

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

The Earth is a huge planet this is covered by 70 percent water. Astonishingly from this 70 percent the human population can only use 1 percent of the world’s water the rest of it is salt water, frozen, or in some way unattainable (Santa Clara Valley Water District, 2016). Humans have found many different ways to obtain this 1 percent of fresh water they need, but the techniques vary depending on location. In San Jose, California we obtain our water from 3 major sources: groundwater, imported surface water, and local mountain surface water. These 3 sources contribute different amounts of water to the San Jose community. Imported surface water composes about 50 percent of our water supply, while ground water composes roughly 40 percent, and local mountain surface water composes approximately 10 percent (Santa Jose Water Company, 2016). However, these percentages can change due to factors such as weather and global warming.

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.

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 can be defined as a colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, rain and is the basis of the fluids of living organisms. Water is located all around Canada as it takes up about nine percent of Canada. Canada has about 20 percent of the world’s fresh water however only 7 percent of that is renewable as most is trapped in underground aquifers and glaciers. Canada has about twenty percent of the world’s fresh water resources. Everyone uses water, as it is a basic need to live. Water is also used for agriculture and industrial purposes.

The hydrological cycle is where water is stored in places like oceans and ponds, and then evaporated. Next, the water is condensed. Finally, water is rained down as precipitation and accumulates in ponds and oceans. This cycle continues repeatedly. Human activities that are detrimental to this cycle

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).

The Earth is a huge planet this is covered by 70 percent water.

Attention-getter: Many of us in the United States take for granted that we would always have an infinite supply of fresh water. This is not true; the authors of the Gale Encyclopedia of Science, K. Lee Lerner and Brenda Wilmoth Lerner wrote that, “less than 3% of water on Earth is fresh water” (Lerner and Lerner.)

diluted enough that they are no longer a problem. Of all the water on the earth,

While reading chapter 17 I read and was interested about water. The earth is covered with mostly water, compared to actual land. To be exact 71 percent of the earth is water where as the land mass is 29 percent. While reading the chapter a topic that caught my attention was where it talked about the water cycles. I think this would be an important factor the the water system/or to write about because without the water cycles we probably wouldn't have any water. One example of a cycle would be the hydrologic cycle this is where water runs off into the oceans, lakes, or rivers, whether it be above ground in rivers, or streams or underneath the ground. Another example is precipitation which most people know as snow, rain, sleet, hail. Precipitation

71 percent of the earth’s surface is made of water. 97 percent of earths water is saline water and not safe for human consumption. This leaves just 3 percent of earth’s water as fresh water most of which is icecaps and glaciers. 68 percent of the fresh water on Earth is found in icecaps and glaciers. 30 percent of fresh water is found in ground water leaving around .3 percent of earth’s water as surface fresh water. Of the .3 percent of surface fresh water the great lakes make up 84% of North America 's surface fresh water and about 21% of the world 's supply of surface fresh water.

Water covers about two thirds of the total surface of Earth, but most of that is saltwater. Humans must drink freshwater to live. 97% of the water on Earth is saltwater, while only 3% of Earth's water is freshwater. And 70% of the freshwater is ice in glaciers, ice caps and permanent snow. The small amount of freshwater remaining is distributed for use to the Earth's 6 ¾ billion people for agriculture, industry,

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.
