Question

1. what is the correct order for the process of water eroding soil?

sheet erosion, gullies, rills
gullies, rills, sheet erosion
sheet erosion, rills, gullies
rills, sheet erosion, gullies

Explanation:

To determine the correct order of water - eroding soil, we need to recall the stages of water - induced soil erosion. Sheet erosion is the initial stage where a thin layer of soil is removed by water over a large area. Then, as the water flow becomes more concentrated, rills (small channels) form. Finally, with further erosion and concentration of water flow, gullies (larger and deeper channels) are created. So the correct order is sheet erosion, rills, gullies.

Answer:

The option with the correct order is: sheet erosion, rills, gullies (the fourth option in the list of choices, with the text "sheet erosion, rills, gullies").
