How does sediment loss affect land and soil quality?

A natural process, which can take place due to water, wind, or other kinds of erosion is considered as sediment loss. However, when much of the sediment gets lost, it can even result in the weakening of the undermine ecosystems, foundations of homes, and even can lead to the destruction of landforms.  

The loss of sediment influences the quality of soil and land as it signifies a loss in nutrients, which the land may require for doing vegetation. It can also result in flooding that can conduct toxins into the water bodies.  

out of these options:

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or
