The element of nature that can cause mechanical weathering by flowing over or carrying rocks along in a current is water.

Here's how water causes mechanical weathering:

* Abrasion: Water carries sand, gravel, and other sediment particles, which act like sandpaper grinding against rocks, wearing them down. This is particularly effective in fast-flowing rivers and streams.

* Hydraulic Action: The force of rushing water can create pressure that can crack rocks and break them apart. This is especially common in areas with strong currents or waterfalls.
