A monolith is a geological feature. It is a massive stone or rock.

Uluru is often called the world's largest monolith

Erosion usually causes the geological formations, which are often made of very hard and solid igneous or metamorphic rock.

In other words, a monolith is what's left after most of an original rock or mountain is worn away.
