Question

Why is it that on one hand coal is found in plenty, yet it is scarce, while a rotten fruit is rare but not scarce?(3 marks)

Answer 1

in ancient times there were giants all over the earth so when these died due to pressure and heat they were melted and formed high density of oil.
so in the last 80 to 100 years we had used a large amount of petroleum bi product and now it's percentage is getting down.
