Hey mate ,hope this will help you :)
a)A ridge or a mountain ridge is a geographical feature consisting of a chain of mountains or hills that form a continuous elevated crest for some distance. The sides of the ridge slope away from narrow top on either side.
b)A gap is a low area between two higher-elevation landmasses, such as mountains. Gaps are similar to passes, but more rugged and difficult to navigate.
c)A pass is a gap, or break, in high, rugged terrain such as a mountain ridge. A pass forms when a glacier or stream erodes, or wears away, the land between areas of higher terrain.
d) A saddle is the lowest area between two highlands (prominences or peaks) but has two wings which span the divide (the line between the two prominences) by crossing the divide at an angle, so is concurrently the local highpoint of the land surface which falls off in the down direction.
