La tectónica de placas 2
Elige la o las respuestas correctas
1 / 11
Uno de los siguientes fenómenos NO puede ser explicado mediante la teoría de la Tectónica de placas, señálalo
la localización de los volcanes
la juventud de las cordilleras
la localización geográfica de los terremotos
las capas de carbón en la Antártida (indican un pasado climático templado y húmedo)
la juventud de los suelos oceánicos
las zonas climáticas del planeta
Las fosas submarinas
En las fosas
la anomalía de la gravedad es positiva
se producen muchos volcanes
la anomalía de la gravedad es negativa
¿Qué fenómeno geológico NO se da en los límites convergentes entre placas?
volcanismo
formación de rift valley
orogénesis
compresión horizontal
El plano de Benioff-Wadati es una prueba que ratifica la teoría de la Tectónica de placas porque
refleja el descenso del suelo oceánico que subduce en las zonas de fosas
coincide con las dorsales oceánicas
permite predecir los terremotos de las fallas transformantes
localiza los rift valleys de los continentes
Los orógenos se originan en los bordes de placas convergentes por
Las cordilleras pericontinentales se caracterizan por
Cuando dos placas oceánicas colisionan
se forma un arco volcánico en las dos
no se forma un arco de islas volcánicas
se forma un arco volcánico en la que no subduce
se forma un arco volcánico en la que subduce
Los orógenos bicontinentales
Cuando convergen dos placas que en el frente de contacto están formadas por océano
