Answer:
Subduction zones are collision between two tectonics plates such that one of the plates is subducted to the mantle (or sinks) directly below the other plate
Whereby the densities of the convergent (colliding) continental plates are lower than the density of the mantle, subduction is prevented from occurring, and subduction zones are not formed at the continental-continental convergent boundaries
Explanation:
A geografia desempenha um papel significativo no processo de desenvolvimento. Três características espaciais influenciam o desenvolvimento econômico de uma região: densidade, distância e divisão
