Types and Characteristics of Volcanoes

The video tutorial by Andy from Classroom Nation explores the topic of volcanoes, focusing on four main types: cinder cone, shield, composite (stratovolcano), and lava domes. Each type is described in terms of its characteristics, formation, and examples. The video also discusses the three states of volcanoes: extinct, dormant, and active, providing examples for each. The tutorial aims to provide a comprehensive understanding of volcanoes, their types, and their states.

What is a volcano?

• A type of earthquake

• A vent connecting magma to the Earth's surface

• A large body of water

• A type of cloud formation

Which type of volcano is created from a single eruption?

• Lava dome

• Shield volcano

• Cinder cone

• Composite volcano

What is a characteristic feature of shield volcanoes?

• They are very steep

• They are the smallest type of volcano

• They have low viscosity lava

• They are formed from a single eruption

Which volcano type is known for its explosive eruptions?

• Lava dome

• Composite volcano

• Shield volcano

• Cinder cone

What is the main reason composite volcanoes have a symmetrical shape?

• Presence of multiple vents

• Low viscosity lava

• Single eruption

• Accumulation of explosive matter and viscous lava flows

What happens to the outer surface of a lava dome as it grows?

• It becomes steeper

• It flattens out

• It erupts explosively

• It cools and hardens

Which type of volcano has very viscous lava?

• Shield volcano

• Cinder cone

• Composite volcano

• Lava dome

What is an extinct volcano?

• A volcano that will never erupt again

• A volcano that is currently erupting

• A volcano that is dormant

• A volcano that has erupted recently

Which volcano state is considered an immediate threat?

• All of the above

• Active

• Dormant

• Extinct

What is an example of a dormant volcano?

• Ben Nevis

• Mount Fuji

• Sakurajima

• Moanalua
