The Cause And Effects Of Acid Mine Drainage

... leachate, seepage, or drainage that has been affected by the natural oxidation of sulfur minerals contained in rock which is exposed to air and water. The major components of ARD formation are reactive sulfide minerals, oxygen, and water. Biological activity and reactions is what is responsible for the production of ARD. These reactions make low pH water that has the ability to mobilize heavy metals contained in geological materials with which it comes in contact. "ARD causes a devastating impact on the quality of the ground or surface ...

Dna Chips And The Pharmaceutical Industry

... also called the DNA array or biochip. These DNA chips are the newest tools being used in the study of genomics. DNA chips are changing the way researchers analyze the genetic make-up of cells, and will soon render traditional pharmaceutical research obsolete. This allows for whole new generations of drugs that will be made to combat diseases by effecting changes in a their specific genetic design. PROBLEM STATEMENT Currently the pharmaceutical industry is a very high risk industry in which fewer than one in ten promising drug products ...

How Earthquakes Are Caused

... to continent plate boundary, the sea floor lithosphere is subducted into the mantle, with almost the same effects. Most islands and island chains are results of volcanic activity. You see, even though neither plate is actually being subducted on two of the convergent plate boundaries, one plate is pushed a bit under the other normally. At the sea floor to continent boundary, the sea floor is subducted. As the plates move together, molten material from the mantle seeps up between the converging plates. The gap is closed as the plates move ...

Global Warming

... how the earth's climate responds to these gases, global temperatures are rising. Energy from the sun makes the earth's weather and climate, and heats the earth; in return. Greenhouse gases (water vapor, carbon dioxide, and other gases) trap some of the energy that leaves, botteling heat like the glass panels of a greenhouse. Without this natural "greenhouse effect," temperatures would be alot lower than they are now, and life like today would not work. Instead, thanks to greenhouse gases, the earth's average temperature is better, ...

Comets

... coma is composed of atoms and molecules of gas that travels with the nucleus. The coma may be up to 100,000 kilometers in diameter. The third feature of a comet is the head. The head is just the name given to the coma and nucleus. The last of the features of the comet are the tails. Most have two tails. One tail is made from dust particles and the other, called ion tail, is made gases. As a comet approaches the sun, the frozen gas becomes unfrozen which causes the dust particles to become free. Light pressure from the sun and some o ...
