500
Which layer is made of magma?
mantle
500

Most earthquakes and volcanoes in the world occur at the Ring of Fire because the plate goes under. This is called a ______________.
subduction zone
plate boundary

A subduction zone is when two plates push into each other and makes mountains. Explain what is happening.
It is an example of a convergent boundary. One plate is moving under the other one and pushing it up.
