• Caldera

• Shield

• Cone

• Scoria Field

Which type of volcano forms from runny, low-viscosity lava that spreads over wide areas?

• Cone

• Caldera

• Scoria Field/Shield

• Lava Dome

What is a caldera?

• A wide, flat volcano with runny lava

• A volcano with a collapsed crater

• A volcano with steep sides

• A mountain formed by earthquake uplift

What is the name of the main channel that lava travels through inside a volcano?

• Vent

• Conduit

• Ash cloud

• Chamber

In the volcano structure diagram, which part is located at the very bottom, storing molten rock?

• Conduit

• Magma Chamber

• Crust

• Ash cloud

What does high viscosity mean in the context of lava?

• It flows quickly

• It is cold

• It is thick and slow-moving

• It spreads far and fast

In the viscosity investigation, what was the independent variable?

• Number of squares moved

• Type of substance used (e.g. water, ketchup)

• Time measured

• Size of the tray

What was the purpose of counting how many squares a substance moved on the laminated grid?

• To measure temperature

• To test smell

• To measure viscosity based on flow

• To record colour

Which of the following is true of a fair test?

• You change many variables at once

• You only measure one thing and ignore everything else

• You change one thing, measure one thing, and keep the rest the same

• You only observe with no measurements

What type of volcano is likely to form from lava that doesn’t flow very far and piles up near the top?

• Scoria Field/Shield

• Caldera

• Cone

• Fault Line
