Which of the following landforms rises well above its surroundings?
a. a canyon
b. a plain
c. a valley
d. a mountain

Option: D. a mountain

Explanation:

A mountain is the only landforms on the earth that rises above its surroundings. Mountains created due to the moving of the tectonic plates on the crust. When two plates of the earth's crust crash into each other, the land pushes upwards and forms mountains. Mountains have steep, sloping sides and rounded or sharp ridges.                                      

I believe the answer is D. a mountain.

Explanation:

Mountains often form when pressure under Earth's surface pushes upward, yet many factors impact their ultimate height, including the erosion of the areas between mountains, known as channels.

If you search for mountains, they should be taller than caynoyns, plains, and valleys.
