Which is an example of natural erosion? ice forming in cracks of rocks acid rain falling on sidewalks waves washing over rocks on the beach water washing away soil in an area with off-road vehicles

 waves washing over rocks on the beach

Explanation:

A natural erosion is a phenomena of removal of the top layer of the soil or any other surface material by the action of the natural physical agents like water, wind and others. Waves washing over rocks on the beach is the correct example of natural erosion because waves from any water body are naturally generated by the effect of wind and gravity these can wipe the surface materials present over the rocks on the beach.

object 2 because all the other ones are wrong

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
