Question

1. what type of volcano forms rapidly and is the shortest - lived type of volcano?
2. which type of volcano is the gentlest and forms the hawaiian islands?
3. what are stratovolcanoes (composite) formed from?
4. why do composite volcanoes (stratovolcanoes) have the most violent eruptions?
5. which type of volcano contains a lava dome and is the most common volcano type?
6. which type of volcano is the largest?

Explanation:

1. This volcano type forms from small, explosive bursts of gas-rich lava and ash, building up quickly but not lasting long.
2. This broad, shallow-sloped volcano forms from fluid basaltic lava that flows easily over large areas, matching the formation of the Hawaiian Islands.
3. Stratovolcanoes build up over time from alternating layers of different volcanic materials.
4. The thick, viscous lava traps volcanic gases; as pressure builds up dramatically, it releases violently during eruptions.
5. This volcano type often has a central lava dome, formed from thick lava that doesn't flow far, and is the most frequently occurring volcano type.
6. This massive volcano type forms from the accumulation of fluid lava over millions of years, growing to enormous sizes.

Answer:

1. Cinder cone volcano
2. Shield volcano
3. Alternating layers of viscous lava, ash, cinders, and other volcanic debris
4. Their thick, silica-rich lava traps large amounts of volcanic gases, leading to extreme pressure buildup that erupts violently when released.
5. Lava dome volcano (or composite volcano with a lava dome core; most commonly classified as lava dome volcano for this trait)
6. Shield volcano
