Question

How does terrace farming help in soil conservation?
A. Prevents water flow
B. Prevents soil erosion only
C. Prevents it from gathering speed and washy soil away
D. Manipulates water flow

Answer 1

Hint: In horticulture, a terrace is a bit of a slanted plane that has been cut into a progression of progressively retreating level surfaces or stages, which look like strides, for the motivations behind more viable farming. This sort of finishing is hence called terracing.

Complete answer:
Terrace development, strategy for developing harvests on sides of slopes or mountains by planting on graduated terraces incorporated with the incline terrace farming. In this, a terrace is a bit of the slanted plane that is cut into a progression of progressively subsiding stages that take after advances. This keeps downpour from washing endlessly soil, henceforth forestalling soil erosion. The significant advantage is the preservation of soil and water. Terraces diminish both the sum and speed of water moving over the soil surface, which incredibly lessens soil erosion.
Hence, option (C) is correct.

Note: The terrace farming give these additional advantages:
(1) The complete region can be cultivated since grassed streams are not required.
(2) At the end of grassed streams likewise dispenses with the bother they cause when plowing or applying herbicides.
(3) THe top releases are diminished because overflow is incidentally put away.
(4) The silt and different pollutants settle out behind the terrace edge before dirtying water in an accepting stream In many frameworks, the terrace is a low, level edge of earth worked over the slant, with a channel for overflow water simply over the edge.
