Solution
The correct option is B Soil is protected against loss
Soil conservation is a method of
protecting soil from getting eroded either by wind or by water.
Few soil conservation methods include:
Graduated terrace steps
which are commonly used to farm on hilly or mountainous
terrain. Terraced fields decrease both erosion and surface runoff.
Wind breaks: Row of trees or a
fence, wall, or screen that provides shelter or protection of soil from the
wind.
Conservation tillage is a method
of preparing soil from getting eroded. This technique involves leaving the previous
year crop residues until the next crop is planted.
