However, where tectonic plates carrying mid-ocean ridges converge with continental plates, we see the following effects:
* Volcanic activity: The subduction of oceanic plates under continental plates creates volcanic arcs along the coastlines. Examples include the Andes Mountains in South America and the Cascade Range in North America.
* Earthquakes: The movement and friction between plates along these convergent zones can cause earthquakes.
* Formation of trenches: Deep trenches are often formed at the point of subduction where the oceanic plate is pulled under the continental plate. The Mariana Trench, the deepest point on Earth, is an example of this.
So, while the mid-ocean ridges themselves don't intersect land, the tectonic processes associated with them do have a significant impact on landforms and geological features along coastlines.
