This video was about two earthquakes that occurred in the ring of fire. Two earthquakes happened on the school holidays in Samoan and Sumatra. Some of the largest earthquakes we’ve seen have happened in the ring of fire, an trail of land. The thin, cool layer that floats on top of the earth is called the crust. It is made up of tectonic plates, which quite a few meet up along the ring of fire. Underneath the crust is molten hot lava. Is there another type of plate? What are tectonic plates made of? Earthquakes can really actually happen anywhere, not just in specific places.
