Question

1. choose the best answer.

_____ volcanoes have no activity, but they have been around for thousands of years.
dormant
active
extinct
cinder cone

1. choose the best answer.

which type of magma would flow faster due to a lower viscosity?
magma with less silica in it
magma with more silica in it

Explanation:

• For question 4:
• Dormant volcanoes are those that are not currently active but have the potential to erupt again. Active volcanoes are currently erupting or have erupted recently. Extinct volcanoes are those that are no longer active and are not expected to erupt again. Cinder cone is a type of volcano, not a state of activity.
• For question 5:
• Magma with less silica has lower viscosity. Viscosity is a measure of a fluid's resistance to flow. Lower viscosity means the magma will flow more easily. Magma with more silica has higher viscosity and flows more slowly.

Answer:

1. Dormant
2. magma with less silica in it
