The theory of plate tectonics states that Earth's plates are always in motion. What geological evidence supports this statement?
Continental and oceanic plates differ in densities.
Selsmic activity occurs along plate boundaries.
Less dense plates always subduct beneath the more dense plates.
The sizes and shapes of continents remain the same over time.
Answer:
Seismic activity occur along plate boundaries.
Explanation:
Since the plates are constantly moving, the places where the plates meet, the boundaries, have seismic activity.
The geological evidence that supports this statement is that seismic activity occurs along plate boundaries. So, the correct option is B.
What are tectonic plates?Tectonic plates are huge slabs of rock that divide Earth's crust and move constantly to reshape the Earth's landscape. Such plates are also known as lithospheric plates and are generally composed of both continental and oceanic lithosphere.
Since the tectonic plates are constantly moving and the places where the plates meet and form the boundaries have seismic activity.
Therefore, the geological evidence that supports this statement is that seismic activity occurs along plate boundaries.
