Answer:
A. Natural gas well
Explanation:
The hydrogen is a gas that can be found in numerous places on Earth, as it is found in all of the spheres. The water has it as one of the two chemicals that make it, it can be found in solid quantities in the atmosphere, as well as in the lithosphere. One place where this gas can not be found is a natural gas well. The natural gas is a fossil fuel, but it doesn't have hydrogen in its composition. This gas is mostly made out of methane, with smaller percentages of ethane, propane, butane, and pentane. If the situation is that the natural gas is almost entirely composed of methane, then it is considered to be a dry gas.
Answer:
1- One of the most immediate and obvious effects of worldwide warming is the increase in temperatures around the world. The average worldwide temperature has increased by about 1.4 degrees Fahrenheit (0.8 degrees Celsius) over the past 100 years, according to the National Ocean-related and (related to the air outside) Management (NOAA).
The (related to the air outside) carbon dioxide concentration has risen from about 270 parts per million (ppm) before 1700 to about 355 ppm today. Climate changes, including a mean worldwide surface temperature rise of between 2.8 and 5.2°C, have been (described a possible future event) by five independent general circulation models (GCMs) for a doubling of the carbon dioxide concentration. The goals of this paper are to examine plant responses to rising carbon dioxide levels and (related to the Earth's weather) changes and to understand/explain the results of these changes on crop water use and water supplies for the United States.
2- Human activity has increased the direct warming effect of carbon dioxide in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Once-a-year (glass building where plants are grown) Gas Index.
I hope this helped you! Make sure you put this in your own words, and if you want me to put it in your own words for you, let me know! Also, you do not have to write all of that, just write the most important stuff! : )
Answer:
mountain systems and fresh water
Explanation:
mountain systems are a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Take the Himalayan mountains for example.
Fresh waters are natural occurring waters except seawater and brackish water. for example they have lake Baikal,the Yangtze river etc.
