Answer the questions below to learn more about the evidence that supports the theory of plate tectonics. 1. Based on the theory of plate tectonics, would you expect to find very new rock or very old rock at an oceanic ridge? Explain why. if they old they can Very new Frock because get damaged easy. are 2. Based on the theory of plate tectonics, would you expect to find very new rock or very old rock in an oceanic trench? Explain why. 3. In the Pacific Ocean, there is a plate boundary between two tectonic plates: the Pacific Plate, which contains some of the oldest oceanic crust on Earth, and the Mariana Plate. The Mariana Trench, the deepest oceanic trench on Earth, is located at this boundary. Nearby, there is an arc of volcanic islands called the Mariana Islands. Based on this information, what type of plate boundary is this? How do you know?

beneath the other. Unlike a divergent boundary where new
crust is created, a convergent boundary is where old crust is
destroyed as the plate subducts into the hot mantle. Often,
volcanoes form on the other plate as a result of
this subduction.
Transform boundaries are places where plates slide
past each other. Crust is neither created nor destroyed at
transform boundaries, but the movement of plates at these
types of boundaries can cause earthquakes.
