Quizplus · Accepted Answer

Depletion of underground aquifers and water logging of irrigated soils are both examples of human-caused changes that occur over a gradual period of time, making option C the best choice. Option A (natural and gradual) does not apply as these changes are primarily caused by human activities like excessive groundwater pumping and irrigation. Option B (human caused and catastrophic) does not apply as these changes do not typically result in sudden or disastrous events. Option D (natural and catastrophic) does not apply as these changes are not primarily caused by natural forces.
