Final answer:
Dome mountains and volcanic mountains form through different processes and have distinct characteristics.
Step-by-step explanation:
Dome mountains and volcanic mountains form through different processes and have distinct characteristics. 
Similarities:
- Both types of mountains are formed by internal forces of the Earth's crust.
 - Both types of mountains have a conical shape, although the slopes of dome mountains are generally gentler than those of volcanic mountains.
 
Differences:
- Dome mountains are formed by the uplift and folding of rock layers, while volcanic mountains are formed by the eruption of magma onto the Earth's surface.
 - Dome mountains are non-explosive and are made up of hardened sedimentary or metamorphic rocks, while volcanic mountains are formed through explosive eruptions and are composed of volcanic materials such as lava and ash.
