Final answer:
The Mid-Ocean Ridge is an example of a divergent plate boundary where new oceanic crust is formed through volcanic activity.
Step-by-step explanation:
The type of plate tectonics that would be observed at the Mid-Ocean Ridge is a divergent plate boundary.
At the Mid-Ocean Ridge, two tectonic plates are moving away from each other, creating a gap where new oceanic crust is formed through volcanic activity. This process is called seafloor spreading. As the plates separate, magma rises from the mantle and solidifies to form new crust.
One example of a mid-ocean ridge is the Mid-Atlantic Ridge, which runs down the center of the Atlantic Ocean.
