Some roads are salted heavily in winter . describe one way place ts growing near these roads could be harmed my the salt

Salt at higher concentrated levels causes soil aggregates to break down, collapsing soil pores and reducing movement of air and water, thus causing less water infiltration and increased erosion. All of this creates a surface above the soil and once it dies it creates a crust like blockade, keeping saplings from breaking through. This also basically suffocates the plants already living there. Hope it helped!!

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.

They are all solids.
