The feature you are describing is known as a cliff. Cliffs are formed by erosion or tectonic activity and are characterized by a steep vertical or near-vertical rock face. They can be found at the edge of plateaus, mountains, or along coastlines.
A crag is a rugged outcrop or a steep rock face on a mountain, often used for rock climbing. A cliff is a steep rock face or slope, typically found near a body of water or at the edge of a plateau. Cliffs are usually taller and more vertical than crags.
This is called a cliff, which is a vertical or near-vertical rock exposure. Cliffs often form at the edge of a plateau due to erosion or tectonic activity, creating dramatic and sometimes dangerous landscapes.
A vertical edge is A line that go straight up and down
Terracing would be the most useful Inca advancement for the farmer living on the edge of a steep mountain. Terracing involves creating flat areas on the mountain slope, which allows the farmer to plant more crops by increasing the amount of arable land available for cultivation. This technique helps prevent erosion and provides better water management for the crops grown on the mountain.
Waterfalls at the edge of a mountain are usually formed by rivers or streams flowing over the edge due to the steep terrain. The force of gravity causes the water to cascade down, creating a dramatic waterfall. Erosion and changes in underlying rock formations also contribute to the formation of waterfalls at mountain edges.
A line of steep cliffs is known as a cliff face or cliff edge. Cliffs are steep rock faces formed by erosion or tectonic activity, and they can be found along coastlines, mountain ranges, or canyons. Cliff faces can be dangerous to navigate and should be approached with caution.
The edge of a mountain cliff is called a precipice.
Every edge that is pointing straight up and down is vertical.
An escarpment is an edge of a plateau usually a steep and jagged cliff.
It is called the Continental Shelf
The steep side of the edge of a continent is called a continental slope. This feature marks the transition between the continental shelf and the deep ocean floor.
