Volcanoes Review

Front

What type of volcano is characterized by fluid lava that flows easily?

Back

Shield volcanoes are characterized by fluid lava that flows easily.

Front

What is the largest shield volcano on Earth?

Back

Mauna Loa is the largest shield volcano on Earth.

Front

Where are the Hawaiian islands located?

Back

The Hawaiian islands are located at a hot spot.

Front

What type of lava creates lava domes?

Back

Lava domes are created by viscous lava that does not move very far from the vent.

Front

What geological feature would you expect to find in a cross section of a composite volcano?

Back

You would expect to find alternating layers of rock and ash in a cross section of a composite volcano.

Front

What is a hot spot in geological terms?

Back

A hot spot is a location where magma from deep within the Earth's mantle rises to the surface, often creating volcanoes.

Front

What are the main characteristics of composite volcanoes?

Back

Composite volcanoes are characterized by their steep profiles and are formed from alternating layers of lava flow, ash, and other volcanic debris.

Front

How do shield volcanoes differ from composite volcanoes in terms of eruption style?

Back

Shield volcanoes typically have non-explosive eruptions due to their fluid lava, while composite volcanoes can have explosive eruptions due to more viscous lava.

Front

What is the primary composition of lava that forms shield volcanoes?

Back

The primary composition of lava that forms shield volcanoes is basalt.

Front

What is the significance of the term 'viscous' in relation to lava?

Back

Viscous lava is thick and sticky, which prevents it from flowing easily and can lead to the formation of lava domes.
