4. Earthquakes and volcanoes in the subduction zone
Earthquakes and volcanoes in the subduction zone. Eg as the Pacific Plate goes under the Indo-Australian Plate. The earthquakes follow the line of the plate going down.

5. A deep ocean trench lies to the east of the North Island.

6. The trench shows that in the North Island the Pacific Plate is diving beneath the Indo-Australian Plate, creating the North Island volcanoes.

A whole line of volcanoes follows the subduction zone, including many under-sea volcanoes.

8. What is a Volcano?
A volcano is an opening in the earth’s crust out of which magma, gases and solid material escape.
The material coming out of a volcano comes from deep inside Earth, usually the mantle.

9. Where are Volcanoes Found?
Around the Pacific Ocean is a ring of ~200 active volcanoes.
This area is called the Ring of Fire.

10. Where are Volcanoes Found?
Most volcanoes occur on plate boundaries.
Some volcanoes also occur over hotspots.
A hotspot is a spot inside the mantle that heats areas of the plate above it.
