Question

Consider the following statements about Erosion:
A. Accelerated erosion is man made and it erodes soil faster than the geologic erosion
B. Attrition is mechanical breakdown of soil particles due to collision with each other
C. Saltation is the transportation of soil particles by rolling over the stream beds in the form of mud
D. Splash/Raindrop erosion is removal of thin layer of soil from soil surface
E. Rill erosion is the advance stage of gully erosion
Choose the correct answer from the options given below:

• A. A, B, C Only
• B. B, C, D Only
• C. C, D, E Only
• D. B, C, D, E Only

Hint:

Erosion sequence:
Splash \(\rightarrow\) Sheet \(\rightarrow\) Rill \(\rightarrow\) Gully.
Saltation: particle transport by rolling.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Erosion is the process of soil removal.
It has different types and processes.

Step 2: Key Formula or Approach:
No specific formula.
Need to know erosion processes.

Step 3: Detailed Explanation:
A. Accelerated erosion is man-made and faster than geologic erosion - correct.
B. Attrition is mechanical breakdown due to collision - correct.
C. Saltation is transportation of soil particles by rolling over stream beds - correct.
D. Splash/Raindrop erosion is removal of thin layer of soil - this is actually sheet erosion.
Splash erosion is the detachment of soil particles by raindrop impact.
Thus, D is incorrect.
E. Rill erosion is an advance stage of gully erosion - this is incorrect.
Rill erosion is the formation of small channels, which advance to gully erosion.
So, gully erosion is the advance stage of rill erosion, not the other way.
Thus, E is incorrect.
So, A, B, and C are correct.

Step 4: Final Answer:
The correct statements are A, B, and C.
Hence, the correct option is (A).
