Answer: Mountain
Step-by-step explanation:
A mountain is a large, natural rise in elevation. It's sides are steep and sloppy and as a result of the rise, bedrock is exposed on those sides. Mountains have peaks which are their tallest points.
Mountains and hills are similar but with certain definitions, mountains are taller than hills. There are several famous mountains in the world such as Mt. Everest and Mt. Kilimanjaro.
