Yes.

That depends on the soil.

The effect of salt water is the greatly strengthen the first reflection 
from the earth in the far field, which forms the vertical pattern. In 
directions other than salt water, it's the usual reflection from lossier 
earth.

The earth affects verticals two ways. First, loss due to return currents 
in the soil under the antenna, which is reduced by a good radial or 
counterpoise system. Second, loss in that first reflection.
