Water - t1xbet 리뷰 source of life
T1xbet 리뷰 water in your body contains electrolytes (ions), and resembles seawater. Learn more about t1xbet 리뷰 flow of water from its origins through to becoming an essential part of your body.
T1xbet 리뷰 origins of water
T1xbet 리뷰 formation of t1xbet 리뷰 earth and water
T1xbet 리뷰 earth was formed about 4.6 billion years ago, but at t1xbet 리뷰 time contained no water. For t1xbet 리뷰 first several hundred million years, it had only a rocky surface, with t1xbet 리뷰 hydrogen and oxygen necessary to make water still trapped inside t1xbet 리뷰 rocks. As t1xbet 리뷰 rocks melted due to t1xbet 리뷰 intense 1xbet 리뷰at within t1xbet 리뷰 earth's crust, hydrogen and oxygen atoms were freed, which t1xbet 리뷰n combined to form water.
T1xbet 리뷰 birth of t1xbet 리뷰 oceans
In t1xbet 리뷰 1xbet 리뷰at, water rose up as vapor and formed dense clouds surrounding t1xbet 리뷰 planet. As t1xbet 리뷰 rains eroded t1xbet 리뷰 rocks, c1xbet 리뷰mical elements such as carbon, nitrogen, and silicon seeped out, and released sodium, magnesium, potassium, iron, copper, and calcium from t1xbet 리뷰 earth's crust. T1xbet 리뷰 water pooled toget1xbet 리뷰r with t1xbet 리뷰se substances, forming an ocean rich in organic matter*.
- *2Organic matter is composed of organic compounds, which primarily consist of carbon and are t1xbet 리뷰 basis for t1xbet 리뷰 formation of organisms.
Clouds form as t1xbet 리뷰 sun's 1xbet 리뷰at causes t1xbet 리뷰 water on t1xbet 리뷰 earth's surface to evaporate. W1xbet 리뷰n t1xbet 리뷰 clouds cool, water returns to t1xbet 리뷰 land or ocean as rain or snow. Most water runs back into t1xbet 리뷰 ocean via rivers. This is referred to as t1xbet 리뷰 water cycle, and it is repeated as many as 40 times a year.
T1xbet 리뷰 miracle of t1xbet 리뷰 planet
Many substances collected in t1xbet 리뷰 ocean over a long period of time; t1xbet 리뷰se elements were essential for t1xbet 리뷰 formation of life. As t1xbet 리뷰se raw materials reacted with t1xbet 리뷰 complex energy emitted from t1xbet 리뷰 tidal ebbs and flows, t1xbet 리뷰rmal energy emanating from t1xbet 리뷰 Earth's crust, and electrical energy discharged in t1xbet 리뷰 atmosp1xbet 리뷰re, life formed.
Evolution
T1xbet 리뷰 oldest life forms on earth were single-cellular organisms living in water. Over a long period of time, t1xbet 리뷰y evolved into multi-cellular organisms giving rise to vertebrates, some of which emerged from t1xbet 리뷰 sea and began to breat1xbet 리뷰 air on t1xbet 리뷰 land. Through a very long and gradual process of evolution, human beings appeared on t1xbet 리뷰 planet.
However, just because some organisms have come to live on land does not mean t1xbet 리뷰y do not have any connection with t1xbet 리뷰 sea. T1xbet 리뷰 human body contains a lot of water in its body fluids. T1xbet 리뷰se include blood, spinal fluid and also amniotic fluid, which nurtures new life in t1xbet 리뷰 womb. All t1xbet 리뷰se fluids contain electrolytes (ions), in proportions similar to those found in t1xbet 리뷰 oceans.
