Entre 1908 e 1912, foi proposta pelo geólogo alemão Alfred Lothar Wegener a teoria da deriva continental. Nesta teoria, ele afir

ma que as placas continentais se rompem, separam-se e chocam-se, criando posteriormente cadeias de montanhas.Um dos argumentos mais fortes de Wegener para justificar a deriva continental era que as bordas dos continentes têm formas que se encaixam. Para defender sua teoria, mostrou que as formações rochosas de dois lados do oceano Atlântico - no Brasil e na Africa Ocidental - coincidem em idade, tipo e estrutura.Além disso, costuma conter fósseis de criaturas terrestres que não poderiam ter nadado de um continente ao outro. Sobre a expansão do fundo do mar, na década de 20, o estudo dos leitos dos mares trouxe evidências de que as dorsais oceânicas são zonas onde se cria a nova crosta oceânica.(Certo ou Errado)

Answer:

verdade

Explicação:

A afirmação é verdadeira de que o estudo dos fundos marinhos trouxe evidências de que as cordilheiras oceânicas são regiões onde a nova crosta oceânica é formada. Essa nova crosta oceânica é formada nas cordilheiras do meio do oceano devido à erupção vulcânica no fundo do mar no processo de propagação do fundo do mar. Nas cordilheiras do meio do oceano, um novo fundo do mar é formado continuamente durante o processo de propagação do fundo do mar.

How does a globe and a flashlight can be used to show why the sun appears to move through the sky.
algol [13]

Answer:

In fact, you may point your flashlight (or laser pointer, if you prefer) at the Andromeda galaxy. There is a non-zero probability that one or more of the photons will be seen by some alien in that galaxy when they happen to glance into the sky at the Milky Way. However, you must take care to aim your flashlight not where Andromeda appears now, but where it will be in 3 million years. Good luck!
