Precious gems would be my best guess, it's the only natural rescource that's only in one area. Sooo.... Precious gems i guess
Tectonic activity that thrust mountains up from the ocean. floor because volcanoes come from the center of the earth and when the tectonic plates move it causes some of the lava from the inside of the earth to emerge and come to the surface where the ocean is and forms into an island (s).
Answer:
Densidad.
Explanation:
The greater the density of an oceanic lithosphere plate, the greater the weight of that plate. This will affect the degree of subduction of that card. The higher the density, the greater the degree of subduction and the ability of the plate to descend, forcing the creation of prominent and well-defined trenches on the ocean floor.
The density of the plaque increases as the age of the plaque increases, so we can consider age, another factor in the formation of these trenches.
