At leading continental edges, you will typically find areas of active plate tectonic activity known as convergent boundaries. These are places where two tectonic plates are colliding, with one plate being forced beneath the other in a process called subduction. The leading edge of the subducting plate is often marked by a deep oceanic trench, such as the Mariana Trench in the western Pacific Ocean. This convergence of plates can create mountain ranges, such as the Andes in South America or the Cascades in North America.
At trailing continental edges, you will often find divergent boundaries, where tectonic plates are moving away from each other. This process is associated with the formation of new oceanic crust and the widening of ocean basins. Trailing continental edges can have features like mid-ocean ridges, which are underwater mountain chains, or rift valleys, which are deep depressions formed as the plates separate. The Mid-Atlantic Ridge is a well-known example of a trailing continental edge.
To find out this information, you can study geology and plate tectonics. By analyzing geological maps, seismic data, and satellite imagery, scientists can identify the locations of these convergent and divergent boundaries. They also use technologies like sonar and deep-sea exploration to map the ocean floor and study the geological features present.
