A scientist observes that over several decades, fence posts placed in soil on a slope became tilted. Have erosion, deposition or

Oksana_A [137]

Answer:

Erosion

Explanation:

At first the fence posts were straight up, but over time that became tilted. The reason fro this is erosion. The erosion managed to remove part of the ground in whist he fence posts have been placed, thus their basis has been weakened, and they have tilted. If the process continues they will soon fall on the ground. Deposition has occurred for sure somewhere, but from this information it is not clear where. There has not been deposition on one side and erosion on other as the fence posts would have been standing straight if that happened. The deposition always occurs as a result of the erosion, but the material can be deposited anywhere from few cm away to several thousands of km away., depending on the transferring medium.
