Volcanoes are distinct geological features formed primarily through volcanic activity. When magma from beneath the Earth's crust escapes to the surface, it can either flow out gently to create wide, gently sloping structures or erupt explosively, resulting in steep, towering formations. These volcanic structures can build up over time, leading to the creation of various types of volcanoes, such as shield volcanoes, stratovolcanoes, and cinder cones.

While mountains can be formed due to various geological processes, including tectonic activities and erosion, and plains can arise from sedimentation or weathering, they are not exclusively products of volcanic activity. Valleys also can be shaped by a variety of forces, including glacial or river activity, and do not directly result from volcanic processes. Therefore, the correct answer identifies the specific landform that directly results from the processes associated with volcanic eruptions.
