FAQs on Types of Volcanoes Video Lecture - Geography Class 11 - Humanities/Arts

1. What are the different types of volcanoes?
Ans. There are three main types of volcanoes: shield volcanoes, cinder cone volcanoes, and composite (or stratovolcanoes). Shield volcanoes have broad, gently sloping sides and are formed by fluid lava flows. Cinder cone volcanoes are steep-sided and are formed by explosive eruptions of ash, cinders, and lava fragments. Composite volcanoes are tall and cone-shaped, consisting of layers of lava, ash, and volcanic debris.
2. How do shield volcanoes form?
Ans. Shield volcanoes form from the accumulation of fluid lava flows. The lava, which is low in viscosity, spreads out in thin layers, creating a broad, gently sloping mountain with a shield-like shape. The lava flows extend for long distances, gradually building up the shield volcano over time.
3. What is the formation process of cinder cone volcanoes?
Ans. Cinder cone volcanoes form through explosive eruptions of ash, cinders, and lava fragments. These eruptions occur when gas-rich magma rises to the surface and encounters a vent or fissure. The explosive nature of the eruptions causes the ejected materials to fall back to the ground, building up the steep sides of the cone-shaped volcano.
4. How do composite volcanoes differ from other types?
Ans. Composite (or stratovolcanoes) differ from other types of volcanoes in their structure and eruptive behavior. They are tall and cone-shaped, consisting of layers of lava, ash, and volcanic debris. Composite volcanoes are characterized by their explosive eruptions, which are caused by the interaction between gas-rich magma and the surrounding rocks.
5. What are some notable examples of each type of volcano?
Ans. Some notable examples of shield volcanoes include Mauna Loa in Hawaii and the Galapagos Islands. Cinder cone volcanoes can be found in various locations, such as Paricutin in Mexico and Sunset Crater in Arizona. Examples of composite volcanoes include Mount Vesuvius in Italy, Mount Fuji in Japan, and Mount St. Helens in the United States.
