What are mountains called that are built by successive deposits of volcanic materials?

Volcanic mountains are formed through the accumulation of volcanic materials such as lava, ash, and tephra over time. This process often involves multiple eruptions, where successive layers of these materials are deposited, contributing to the mountain's height and structure. As volcanic activity continues, these layers stack upon one another, creating the distinctive shape and elevation associated with volcanic mountains.

While other types of mountains, such as cinder cone and shield volcanoes, also involve volcanic processes, they have specific characteristics that set them apart from the general category of volcanic mountains. Cinder cone volcanoes are typically formed from the explosive ejection of lava and ash, resulting in a steep, conical shape, while shield volcanoes are characterized by their broad, gently sloping profiles built up by the flow of low-viscosity lava. Dome mountains, on the other hand, are formed through the uplift of rock layers but do not specifically relate to volcanic activity. Therefore, the term "volcanic mountains" accurately encompasses all mountains created by the continuous deposition of volcanic materials, making it the most fitting choice.
