ii. Sinking to the bottom of the swamps
iii. Death of huge ferns and leaves covering the swamps
iv.High pressure turning pete to fossil fuels
v. Formation of sedimentary rock

• A. iii-ii-i-v-iv
• B. iii-ii-i-iv-v
• C. iii-i-ii-v-iv
• D. iii-i-ii-iv-v

Answer 1

The correct option is A iii-ii-i-v-iv

The correct sequence of formation of fossil fuels is: Death of huge ferns and leaves covering the swamps -> Sinking of these dead plants to the bottom of the swamps -> Formation of a spongy layer called pete -> Formation of layers of sedimentary rocks over it -> High pressure of the sedimentary rocks turning pete into fossil fuels.
