The document describes four types of volcanoes and their locations: 1) submarine volcanoes form at mid-ocean ridges where tectonic plates are spreading apart, 2) composite cone volcanoes form in island arcs at convergent plate boundaries, 3) stratovolcanoes form where oceanic plates subduct under continental plates and erupt acidic lava, and 4) shield volcanoes form at hotspots and erupt basic lava non-violently. It also mentions calderas formed by collapse of magma chambers.

2. A 1 2 3 4 Volcanic Environments Submarine volcano erupting under the ocean at the Mid Atlantic ridge, a tensional (divergent) plate margin.

3. B 1 2 3 4 Volcanic Environments Composite cone volcano forming part of an island arc at a compressional margin where two oceanic plates meet and one is subducted under the other.

4. C 1 2 3 4 Volcanic Environments Composite (stratovolcano) volcano found at a compressional margin where an oceanic plate is subducted beneath a continental plate. Lava is acidic and viscous.

5. D 1 2 3 4 Volcanic Environments Shield volcano formed at a hotspot in the earth’s crust. Lava is basic and runny. Eruption is non-violent.

6. 1 2 3 4 Volcanic Environments Match up the volcano with it’s location E 5 Source images wikipedia / USGS Caldera formed by collapse of magma chamber. Crater Lake is an example. Super volcanoes are very large calderas.
