Three landforms that can be created from ash are cinder cone volcanoes, composite volcanoes, and shield volcanoes. Lava plateaus can also be formed.
volcanoes are usually the mountains,the plate boundaries colliding depend on where the volcanoes are formed so they are not purposely always formed by mountains.
The shaped surface of the Earth is particularly featured by the landform. And Earth has three main landforms, (1) the valleys or the lower regions of the Earth and formed from the effect of eroding movement of water over rock and soil, (2) the mountains or a large vertical landforms, the Earth's natural elevation, and (3) the plains or the mostly flat and broad areas landform, more than 50% of the Earth's interior.
