Did you know that the Mariana Trench is one of the deepest parts of the ocean? It's also really dark. My dad nearly had a panic attack just thinking about all of the anglerfish that could be out to get me! He's still a little overprotective. Did you know that the Mariana Trench is also called the Marianas Trench? It was formed by the convergence of the Pacific Plate and the Philippine Plate. The heavier Pacific Plate subducted underneath the Philippine Plate, creating a trench in the ocean floor. The Pacific Plate also pushed upwards on the Philippine Plate from underneath, creating a chain of volcanic islands, the Mariana Islands.
This picture shows how volcanic island chains and ocean trenches are created by ocean-ocean convergence. The islands often have large volcanoes because they are pushed upwards to create mountains and contain magma. Earthquakes are caused often by the plates colliding and sometimes can be very dangerous. The deadly 2011 Japan earthquake and tsunami was caused by ocean-ocean convergence.
Squirt says he doesn't know any of that because he wasn't paying attention. He was too busy seeing how deep he could dive. Turns out he can dive pretty deep, and he got lost for a while, and Dory had to go rescue him! Luckily, he didn't run into any anglerfish or sharks. Well, I should probably get to sleep; we have a long journey ahead of us to get to our next stop. I can't tell you what it is because it's a surprise!
