The Hydrologic Cycle

The hydrologic cycle is the continuous circulation of water between the earth's surface and the atmosphere. It involves various processes such as evaporation, precipitation, infiltration, and runoff. The balance between the inflow and outflow of water is crucial for the sustainability of water resources.

Mass Inflow and Outflow

The mass inflow and outflow refer to the amount of water that enters and leaves a particular system. The mass inflow includes the amount of water that enters a basin through precipitation, surface runoff, and subsurface flow. The mass outflow includes the amount of water that leaves the basin through evaporation, transpiration, surface runoff, and subsurface flow.

Change in Mass Storage

The change in mass storage refers to the difference between the inflow and outflow of water in a particular system. It is the amount of water that is stored in the basin at a particular time. The change in mass storage can be positive or negative depending on the inflow and outflow of water.

The Correct Answer

The hydrologic cycle states that the mass inflow and outflow are equal, and the change in mass storage is the difference between the inflow and outflow of water. Therefore, the correct answer is option D, "mass inflow - mass outflow = change in mass storage." This equation is important in hydrology as it helps to understand the water balance of a particular system and to manage water resources effectively.
