O António tem uma amiga que vive numa ilha Marianas, onde existe uma intensa atividade vulcânica. Tem um outro amigo que mora numa ilha das
Filipinas, onde também existe muito vulcanismo. O António olhou para o mapa
e verificou que nas margens do oceano Atlântico não existe vulcanismo ativo.
Achou estranho, uma vez que os amigos vivem em locais que correspondem a
margens de um oceano. Justifica esta situação.​

A. it is created from magma. the agents of a metamorphic rock is heat and pressure. (heat from intrusion of magma or burial)

The reason why i feel that the theory of plate tectonics is correct because scientists have found dinosaur bones of the same species in africa, asia, and in the americas. which means that they must have been together at one point in time. plate tectonics is also how the hawaiian islands were formed. as the plate hawaii is on was moving north west, magma would melt through the sea bottom and hardening. forming into the island chain. plate tectonics also explains the mariana trench. two plates were moving away from each other and made a giant crack in the ocean floor running 2,550 kilometers (1,500 miles)  long.
