Most soda drinks erode the teeth fastest because they do contain acids- phosporic and carbonic acid.
Gullies are commonly found in steep terrain, such as mountains, hillsides, and cliffs. They form when water erodes the soil and creates channels or grooves in the landscape. Gullies can also occur in agricultural fields or urban areas where poor drainage contributes to erosion.
"Flowers" and "hillsides" are the nouns here.

The fastest part of a meandering river is typically on the outside of a bend where the water accelerates due to the increased centrifugal force. This faster flow erodes the outer bank of the bend and deposits sediment on the inner bank.
Sandy soil tends to erode the fastest due to its loose structure and low capacity to hold onto water and nutrients. When exposed to water or wind, sandy soil can quickly wash or blow away, leading to erosion.

Terrace farming is done to make use of hillsides. This is done because the slopes are too steep for farming. Terraced hillsides help to reduce erosion and surface runoff. This helps to keep the soil in place on the hillsides.
