Answer:
Oceanic trench
Explanation:
On the places where there's convergent plate boundary between an oceanic and continental plate, there's a subduction zone. The oceanic plate is denser, heavier, lower than the continental plate. Because of that, the oceanic plate is moving below the continental plate, slowly getting into the mantle where it is melted and destroyed. On the boundary itself, a gap opens up between the plates, a gap that is under constant pressure and geological activity. This gap is basically a valley at the bottom of the ocean, being much deeper than the surrounding area. The term used for these places is an ocean trench, and there's lot of them around the world where there's a convergent plate boundary between an oceanic and continental plate. The best known of these ocean trenches, also being the deepest place on Earth, is the Mariana trench, located on the boundary between the Filipino and the Pacific plates.
Answer:
Los mares cerrados, como el Mar Mediterráneo, presentan mayores niveles de contaminación porque son entera o mayoritariamente formados por cuencas endorreicas, las cuales no tienen salida directa hacia el océano. De esta manera, las corrientes marítimas no desagotan sus residuos en el océano, sino que continúan retroalimentándose de manera cícilica, con lo que el conjunto de desechos que viaja en dichas corrientes se queda constantemente dentro de la misma cuenca.
