The Ring of Fire Quiz

What is the Ring of Fire?

• A ring of mountains around the Pacific Ocean

• A tectonic region with frequent earthquakes and volcanoes

• A circle of lakes formed by volcanic eruptions

• A single large volcano in the Pacific

Why is the Ring of Fire so geologically active?

• The region has many tectonic plate boundaries

• The Pacific Ocean is shrinking

• Magma flows continuously without stopping

• It is located near the equator

What type of plate boundary causes subduction?

• Divergent

• Convergent

• Transform

• Hotspot

What happens when an oceanic plate subducts beneath a continental plate?

• A mid-ocean ridge forms

• A rift valley is created

• The oceanic plate sinks, melts, and forms magma

• The plates stop moving

Which of the following volcanoes formed due to subduction?

• Mount Fuji (Japan)

• Mauna Loa (Hawaii)

• Icelandic volcanoes

• Mid-Atlantic Ridge volcanoes

What happens at a divergent boundary?

• Plates move apart, and magma rises to form new crust

• One plate sinks under another

• Plates slide past each other

• No movement occurs

What is an example of a divergent boundary?

• San Andreas Fault

• Mid-Atlantic Ridge

• Andes Mountains

• Himalayan Mountains

Why do volcanoes form at divergent boundaries?

• The plates collide, forcing magma to rise

• The plates move apart, allowing magma to rise and form new crust

• The plates grind against each other, creating pressure

• The plates stay still, causing magma to break through

What is the main cause of earthquakes at transform boundaries?

• Plates sliding past each other, creating friction

• Magma pushing through cracks in the crust

• Plates pulling apart and forming new crust

• One plate sinking beneath another

How does plate movement cause volcanic eruptions?

• Movement creates pressure that forces magma to the surface

• Plates break apart and disappear

• Earthquakes release heat that melts rock

• The Sun heats the plates, creating cracks
