LORETO

Compara los siguientes mapas de las placas tectónicas (pag.13) y de los volcanes, de los terremotos y del relieve actual:
a) ¿Qué coincidencias encuentras entre las zonas donde chocan las placas y las grandes cordilleras?
b) ¿Por qué los volcanes y los terremotos se dan en las mismas zonas?
c) ¿Qué relación hay entre la cordillera de los Andes y los fenómenos estudiados?
d) Aplicando tusconocimientos, ¿podrá la cordillera de los Andes cambiar de altura?
e) Si la isla de Pascua se encuentra en la placa de Nazca, ¿se aleja de América o se acerca a ella?

DESARROLLO
Respuesta A: La coincidencia es que en la parte en que chocan las placas hay siempre un cordón montañoso o alguna Cordillera.
Respuesta B: Esto depende de las placas tectónicas que tenemos debajo nuestro. Dependeen que lugares están más separadas o una encima de la otra, y depende sus movimientos es cuando hay terremotos, tsunamis que provocan erupciones de volcanes
Respuesta C: La relación que hay es que todas están en movimientos gracias a las placas tectónicas.
Respuesta D: Es posible, debido a los constantes movimientos de las placas tectónicas, puede que se choquen y produzcan un gran cataclismobajo las cordilleras (solo una parte) y se produzca una erupción o elevamiento de terreno, bueno solo un poco. Pero tiene un 0.1% de probabilidad de que pase.
Respuesta E: Si, si puede ya que las placas cada vez se van corriendo más y más.
