How is dome mountains formed?
Sometimes volcanic eruptions break down mountains instead of building them up, like the 1980 eruption that blew the top off Mount St. Helens. When magma pushes the crust up but hardens before erupting onto the surface, it forms so-called dome mountains. Wind and rain pummel the domes, sculpting peaks and valleys.
What are the characteristics of dome mountains?
Dome mountains are formed where a region of flat-lying sedimentary rocks is warped or bowed upward making a structural dome. Their topography is characterized by a relatively flat, dissected surface sloping gradually toward the surrounding lowlands, or basins.
How are domes formed?
Salt domes result when rock salt rises through overlying sedimentary rock. Salt accumulates as ancient seas dry up over time. Eventually, sediments form over this layer of salt. Salt is less dense than most other rocks, and it slowly moves upward toward the surface, forming a dome-shaped hill.

What is the difference between dome mountains and volcanic mountains?
There are two main types of volcanic mountains: volcanoes and dome mountains. Volcanoes are formed when magma erupts all the way to the surface of the Earth. The magma will harden on the Earth's surface, forming a mountain. Dome mountains are formed when a large amount of magma builds up below the Earth's surface.
