Etymology

Origin of declivity

First recorded in 1605–15; from Latin dēclīvitās “a slope, hill,” equivalent to dēclīvi(s) “sloping downward” ( dē- prefix indicating downward motion + clīv(us) “slope, hill” + -is adjective suffix) + -tās noun suffix; see de-, -ty ²

Explanation

If you're standing at the top of a hill looking down to the bottom, you're staring down a declivity, a downward slope of any kind. The word declivity comes from the Latin words de, which means "down," and clivus, which means "slope." If you're at the bottom of the hill looking up, you'll see the opposite of a declivity. From that position you'll be looking at an acclivity, an upward slope.
