The basic properties of water
By: Lime Red Tetrahedron
Water, although exhibiting a simple chemical structure, demonstrates astounding properties that have time and time again challenged our chemical theories. These properties are those that make this vital substance necessary for life. Unlike similar compounds which are gasses at room temperature, water exists as a...
How to reduce human water consumption
By: Laurie Childree
Water is every where but not all of it is usable. We can't drink the water in our oceans as it is and the animals in the oceans and lakes need that water to survive. We have ground water that isn't drinkable in places and...

The fact that most of the Earth's surface is covered in liquid water has resulted in the favorable conditions allowing life on Earth. Waters unusually high freezing and boiling points and its stability as a molecule have all contributed to life on Earth. Water also...
Saving the Aral Sea
By: Brenda Nelson
The Aral sea sits between Kazakhstan and Uzbekistan, and was once the fourth largest sea in the world. Most people today haven't even heard of it. What was a 68,000 square kilometer sea, and thriving fishing industry, is now a sea that is 10...
How sea levels rise
By: Mishra Planeswalker
You hear it all the time on television, the radio, and in various print media. The sea levels are rising due to a man made phenomenon known as global warming. Unfortunately, the link between these two concepts is often misunderstood, if it is presented at...
How to reduce human water consumption
By: Nayab Naseer
Water covers around two-third of the earth's surface. However, only around one percent of this water is accessible freshwater. The rest is either saltwater found in oceans or water trapped in glaciers. The ever-increasing population places even more pressure than before on the available sources...
How ocean oxygen loss affects ecosystems
By: Nayab Naseer
Thanks to global warming and increased dumping of pollutants in the world's oceans, nearly two percent of the world's ocean is today oxygen depleted "dead zones". This is excluding areas where the quantum of oxygen is far less than what it ideally should be.The...
Ocean oxygen depletion: How and why
By: Nayab Naseer
Oxygen, indispensable to sustain life in this planet, is present in abundance in the earth's atmosphere, and dissolves in water to sustain marine ecosystems as well.However, of late the oceans of the world show an alarming depletion of oxygen content, compared to previous years...
Ocean oxygen depletion: How and why
By: Debbie Luyo
Ocean dead zones are getting bigger. Dead zones are regions of oxygen-deprived ocean where fish, clams, crabs, and other undersea creatures cannot survive. Ocean oxygen depletion, also known as hypoxia, is the result of a decrease in the soluble oxygen concentration of ocean water. According...
By: Darrin A Yarbrough
Acanthaster Planci or, the "Crown of Thorns" starfish has received both fame and notoriety in recent years for its mysterious invasion and decimation of sclaractinean corals on Australia's Great Barrier Reef. Although there are other contributing factors for the decline of corals along the Great...
