Answer: E. Is produced by "fracking", which uses high-pressure water and chemicals to make new "fractures" in the shale that allow the gas to escape to wells.
Explanation:
The Marcellus is a large area in the eastern part of the USA. Natural gas is extracted here through fracking or hydraulic fracturing. This is a process in which water at high pressure is injected into a drilled holes thereby creating holes in the rocks housing the gas and petroleum and sending them into a well
.
While fracking provides natural gas, a cleaner source of energy than coal, fracking has some environmental costs such as ground water contamination and the risk of setting off earthquakes.

The problems with Hawaii's food supply mainly have to do with 90% of the food being imported. Should something happen to the boats, a lot of islanders would not have a way to get food and Hawaii could crumble in just 10 days.This being said, some people have found ways to get their own food should the boats not show up one day.

Explanation:
This is what I put for my answer.
Answer:
b conditions in the atmosphere that occur for years at a time in an area
Explanation:
- Climate is defined as permanent conditions that develop over the area due to its geographical properties such as the latitude, nature of terrain and size shape and area covered by the landmass.
- Its distance from the sun and it's positioning on the globe and is differentiated from the weather that is aggregate conditions that prevail over the region for a short period of time like a few days or hours, etc.
- <u>While the climate of a place can be for months, years, and even decades as the polar climate, tropical climate, the Mediterranean climate, the oceanic climate, the continental climate, and the subarctic climate.etc. Hence is a long term meteorological variable.</u>
