Question

Which of the following is true of water budgets?

Answer 1

Answer:

B. In the winter, when water use is low, precipitation exceeds evapotranspiration

Explanation:

A water budget can be seen as the relationship between the inflow and outflow of water through a specified region.  It gives a general Idea of the relationship between the demand and supply of water in that region.

Evapotransipration is the loss of water from the soil through evaporation from the soil and other surfaces and by transpiration from plants, while precipitation refers to  rain, snow, sleet, or hail that falls to the ground.

During winters due to the cold temperatures, the rate of water loss from the soil and from plants is much lower than the amount of precipitation which is on form of snow.

Snow covers most of the soil, freezing the soil water at the surface of the soil, making it difficult for evapotranspiration to occur. In addition to that, most deciduous trees shed their leaves during this period further reducing the total amount of transpiration in that region.

This makes option B correct
