What is the cause of volcanic activity in New Zealand?

Answer Choices are:

its location on the Eurasian plate and Gorda Plates

its location on a series of dormant volcanoes

its location on the boundary between the Indo-Australian and Pacific Plates

its location on the boundary between the Juan de Fuca Plate and the Indo-Australia Plate

Explanation:

New Zealand lies on the boundary between two tectonic plates. When the subducting plate melts the buoyant magma can come to the surface and erupt. ... Inside the Earth there is a red-hot liquid rock, called magma. Volcanoes happen when magma rises to the surface of the earth, which causes bubbles of gas to appear in it. So B is probably the right one... Hope that helps!!!
