Read the following passage and select the sentence that best supports the following:
Most trenches in the world are located at the perimeter of the Pacific Ocean.

Deep-sea trenches are long, v-shaped, steep-sided valleys on the ocean floor. Their formation is due to plate tectonic activity.  When the leading edge of an oceanic plate meets the leading edge of a continental plate, the crust interacts. Oceanic crust is denser than continental crust, causing the oceanic crust to bend downward. This movement creates a deep v-shape, which becomes a trench. Deep-sea trenches are found between 24,000 to 36,000 feet under water. The deepest known trench is the Mariana Trench in the western portion of the North Pacific Ocean. Its depth is 36,200 feet.

Match your volcano type with the correct description.

Draggable item		Corresponding Item
Cinder Cone Volcanoes		large, gently sloped volcanoes that result from the eruption of basaltic lava
Calderas		large, steeply sided cones that form from alternating layers of pyroclastic material and lava flows.
Shield Volcanoes		small, cone-shaped volcanoes that result from pyroclastic material that falls close to the volcanic vent.
Composite Volcanoes (Stratovolcanoes)		Large, collapsed craters over a volcano's empty magma chamber and are formed after extremely explosive eruptions.
