Which volcano type is known for being broad and dome-shaped?

The broad and dome-shaped characteristics of a shield volcano are due to the low-viscosity basaltic lava it erupts. This type of lava can flow over great distances and accumulates in broad layers. As a result, shield volcanoes have gentle slopes and a sprawling shape that resembles an ancient warrior's shield lying on the ground. Well-known examples of shield volcanoes include Mauna Loa and Kilauea in Hawaii, which showcase these features distinctly.

In contrast, dome volcanoes are typically steep-sided and formed from more viscous lava, which piles up near the vent, leading to a more stratified and compact structure. Extinct and active volcanoes do not describe specific shapes or profiles but refer to the volcanoes' current activity status, rather than their physical form. Therefore, the distinct broad and dome-like structure specifically aligns with the characteristics of shield volcanoes.
