(; -; ) which of the following situations shows an interaction involving all five of earth's spheres?
a) a polar bear floats on an iceberg
b) a farmer in the rain forest growing coffee beans.
c) a glacier flows overland taking rocks and trees with it as it melts.
d) an alligator on the lake shore eats a bird

Option C

Explanation:

The five spheres of earth are Atmosphere, cryosphere, biosphere, lithosphere, hydrosphere.

The glacier(cryosphere) flowing( hydrosphere)by taking rocks( lithosphere)and trees( atmosphere and biosphere) with it self when it melts  is an example which includes all the five spheres of the earth.

Hence, the correct answer is option C
