Question

how did so much energy get into the peat that is present under the arctic permafrost?
a at one time long ago, the earth was at less of a tilt causing more direct sunlight in the arctic which increased the rate of photosynthesis and carbon storage.
b at one time long ago, the earth was at less of a tilt causing more direct sunlight in the arctic which decreased the rate of photosynthesis and carbon storage.
c at one time long ago, the earth was at a greater tilt causing less direct sunlight in the arctic which increased the rate of photosynthesis and carbon storage.
d at one time long ago, the earth was at a greater tilt causing more direct sunlight in the arctic which increased the rate of photosynthesis and carbon storage.

Explanation:

More direct sunlight generally leads to increased photosynthesis as sunlight is a key factor for the process. A greater tilt of the Earth could potentially cause more direct sunlight in the arctic at certain times in the past, which would increase the rate of photosynthesis and carbon - storage in plants that contribute to peat formation.

Answer:

D. At one time long ago, the Earth was at a greater tilt causing more direct sunlight in the arctic which increased the rate of photosynthesis and carbon storage.
