Question

Read the following scene:

Rainwater flows quickly over a grassland, filling lazy streams and soaking deeply into the ground. Days later, nearby vegetation grows quickly and the grassland seems to come to life.
Conclude that the above scene best represents which of the following two loops?

A) precipitation loop and evapotranspiration loop
B) surface runoff loop and groundwater loop
C) precipitation loop and groundwater loop
D) surface runoff loop and evapotranspiration loop

Answer 1

Option (B)

Step-by-step explanation:

The surface runoff usually refers to the flowing of water along an inclined surface over a large or small distance. These waters are accumulated in the land areas, rivers, and streams.

On the other hand, groundwater refers to the water that is present below the surface of the earth. When water accumulates over the land areas that are porous and permeable, it allows the water to percolate down into the deeper zone and eventually becomes groundwater.

In the given condition, the flowing of the water over the grassland areas and adding to the streams refers to the surface runoff loop. And the percolation of water into the deeper root zone and enriching the vegetation refers to the groundwater loop.

Thus, the correct answer is option (B).
