why is coal known as buried sunshine?
Answers
Answer:
Explanation:
Sunshine duration or sunshine hours is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years. It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period.
Sunshine duration is usually expressed in hours per year, or in (average) hours per day. The first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location.[1] Another often-used measure is percentage ratio of recorded bright sunshine duration and daylight duration in the observed period.
Answer:
Coal was formed millions of years ago, when the plants, which grew from sunlight energy were deposited between sand layers. The anaerobic bacteria converted the peat(dead plants) into coal which we use currently. Hence, it can be concluded that coal is actually buried sunshine.
