What is a synonym for "peak"?

The term "peak" refers to the highest point of something, commonly associated with mountains or elevated structures. Therefore, a synonym for "peak" is "summit," which also denotes the highest point or top of a specific place, particularly in geographical contexts. Both terms convey the idea of reaching an apex or maximum elevation, making them interchangeable in certain phrases, such as "the summit of the mountain" or "the peak of the hill."

In contrast, the other options do not share this meaning. "Base" refers to the bottom support or starting point of an object, while "valley" signifies a low area between hills or mountains. "Bottom" describes the lowest part of something, which is opposite in meaning to "peak." Thus, "summit" is the only option that aligns closely with "peak" in context and definition.
