Types and Characteristics of Volcanoes

The video explains different types of volcanoes: composite, shield, and cinder cone. Composite volcanoes have multiple vents and can erupt violently, forming large structures like Mount St. Helens and Mount Fuji. Shield volcanoes, such as those in Hawaii, have a broad shape due to their fluid lava and erupt less dramatically. Cinder cone volcanoes are smaller, with eruptions that build up a cone shape but rarely exceed 1,000 feet in height.

What is a characteristic feature of composite volcanoes?

• They have a single vent.

• They have multiple vents and channels.

• They are the smallest type of volcano.

• They are always underwater.

Which of the following is a famous composite volcano?

• Mount Everest

• Mount St. Helens

• Mauna Loa

• Krakatoa

What shape do shield volcanoes typically have?

• Irregular and jagged

• Flat and square

• Wide and round

• Tall and narrow

Which islands are made up of shield volcanoes?

• Fiji Islands

• Canary Islands

• Galapagos Islands

• Hawaiian Islands

How do cinder cone volcanoes form their shape?

• By the collapse of a caldera

• By the accumulation of ash and lava around the vent

• By the erosion of a mountain

• By the movement of tectonic plates

What is the maximum height cinder cone volcanoes usually reach?

• 3,000 feet

• 1,000 feet

• 500 feet

• 2,000 feet
