Question

Arrange these harmful soil erosion classes from low to very high soil loss. A. Catastrophic erosion, B. Medium erosion, C. Severe erosion, D. Serious erosion, E. Weak erosion.

• A. E \(<\) B \(<\) D \(<\) C \(<\) A
• B. B \(<\) C \(<\) D \(<\) A \(<\) E
• C. C \(<\) D \(<\) E \(<\) B \(<\) A
• D. A \(<\) B \(<\) C \(<\) D \(<\) E

Hint:

Severity of erosion increases from weak to medium, serious, severe and catastrophic.

Answer 1

The Correct Option is A

Concept:
Soil erosion may be classified according to the severity of soil loss.

Step 1: Lowest erosion.
Weak erosion causes the lowest soil loss. \[ \text{Lowest}=E \]

Step 2: Medium and serious erosion.
Medium erosion is followed by serious erosion. \[ B<D \]

Step 3: Severe and catastrophic erosion.
Severe erosion causes high soil loss, while catastrophic erosion causes very high soil loss. \[ C<A \]

Step 4: Final order. \[ E<B<D<C<A \] \[ \therefore \text{Correct Answer is (A)} \]
