Copper mining had gone on there for more than 90 years! The damage couldn’t be reversed overnight. Although I should mention that by 1996, the water in one of the rivers flowing through the basin was clean enough that it was the site of the Olympic white water kayaking competition. ...
The virus has spread faster and wider than any other since the founding of the People’s Republic in 1949, and has proven to be the most difficult to contain. It is both a crisis and a major test for China. The Communist Party of China (CPC) and the Chinese government have addressed ...
Both oil and gas are less dense than water, so they generally tend to rise upward through water-saturated rock and sediment. Oil pools are valuable underground accumulations of oil, and oil fields are regions underlain by one or more oil pools. When an oil pool or field has been discovered...
When the sun's rays strike water surface, some of the water becomes absorbed by the air as water vapor. The warmer the air is, the more vapor it can hold. When the air has absorbed its maximum amount of vapor, it is said to be saturated. If the air is then cooled, some of the...
