Facts About Different Volcano Types

Which of the following best describes the lava of a Shield Volcano?

• Sticky and does not flow far

• Runny and can flow far

• Thick and explosive

• Solidifies quickly

What is a common characteristic of Composite Volcanoes?

• They are wide and flat

• They have explosive eruptions

• They are smaller than other volcanoes

• They have low viscosity lava

Which of the following is an example of a Shield Volcano?

• Mt. St. Helens

• Mt. Fuji

• Mauna Loa

• Paricutin

How do Cinder Cone Volcanoes form their shape?

• By alternating eruptions of lava and ash

• By lava flowing far and wide

• By cinders accumulating around the vent

• By tectonic plates colliding

Explain why Shield Volcanoes are usually not explosive.

• Because they have steep slopes

• Because their lava is runny and has low viscosity

• Because they form from alternating eruptions of lava and ash

• Because they are smaller in size

Compare the slopes of Shield Volcanoes and Composite Volcanoes.

• Both have steep slopes

• Shield Volcanoes have steep slopes, while Composite Volcanoes have gentle slopes

• Shield Volcanoes have gentle slopes, while Composite Volcanoes have steep slopes

• Both have gentle slopes

Why might Composite Volcanoes be considered more dangerous than Shield Volcanoes?

• They are smaller and less predictable

• They have explosive eruptions and sticky lava

• They are located in more populated areas

• They have runny lava that flows far

Analyze the impact of the location of Composite Volcanoes on their formation.

• They form in areas with low tectonic activity

• They often form where two tectonic plates collide

• They form in the middle of tectonic plates

• They form in areas with high rainfall

Evaluate the reasons why Shield Volcanoes can reach massive sizes compared to other types of volcanoes.

• They have explosive eruptions that build up the volcano quickly

• Their runny lava spreads over large areas, allowing them to grow wide and tall over time

• They are formed by the collision of tectonic plates

• They are located in areas with high volcanic activity
