What can be the combined effect of reduced inflow and increased siltation in a lake?

Answer and explanation

Correct answer: Both water volume and effective depth of the lake may decrease

The direct answer is A: both water volume and effective depth may decrease. Reduced inflow means less new water enters the lake. Increased siltation means soil and sediments settle on the bed, raising the bottom and reducing the space available to store water. Together, these changes can lower storage capacity and effective depth, especially if evaporation and use continue. B is wrong because such changes cannot immediately turn a lake into an ocean. C is wrong because silt and low inflow do not automatically create glaciers; glaciers require long-term snow and ice conditions. D is wrong because siltation generally harms water quality and “always” is too absolute. Cue: less inflow + more silt = shallower, smaller capacity.
