Which of the following erosion is not caused by wind?Options :SuspensionSaltationSurface creepSplash erosion

To determine which type of erosion is not caused by wind, we need to analyze each option:

1. Suspension: Suspension erosion is a process where small particles are carried by wind and remain suspended in the air for a period of time. This type of erosion is indeed caused by wind.

2. Saltation: Saltation erosion occurs when wind picks up and transports larger particles, causing them to bounce and collide with the ground. Again, this type of erosion is caused by wind.

3. Surface creep: Surface creep erosion is a slow movement of soil and sediment on the ground surface due to the force of gravity. This type of erosion is not primarily caused by wind, but rather by the effects of gravity.

4. Splash erosion: Splash erosion happens when raindrops hit the ground and dislodge soil particles, causing them to splash and move. This type of erosion is not caused by wind, but rather by the force of raindrops.

Therefore, the type of erosion that is not caused by wind is surface creep.
