TIPOS DE PLACAS
• Las placas litosféricas son esencialmente de dos tipos, según la clase de corteza que
forma la superficie. Hay dos clases de corteza: la oceánica y la continental.
• Placas oceánicas. Están cubiertas íntegramente por corteza oceánica, delgada, de
composición básica: hierro y magnesio dominantes. Aparecen sumergidas en toda su
extensión, salvo por existencia de edificios volcánicos intraplaca, de los cuales los
destacados por altos aparecen emergidos, o por arcos insulares (de islas) en alguno de
sus bordes. Los ejemplos más notables se ubican en el Pacífico: la del Pacífico, la placa
de Nazca, la placa de Cocos y la placa Filipina.
• Placas mixtas. Son placas parcialmente cubiertas por corteza continental y así mismo
en parte por corteza oceánica. La mayoría de las placas son de estas características.
GRACIAS.

  • 6. TIPOS DE PLACAS • Las placas litosféricas son esencialmente de dos tipos, según la clase de corteza que forma la superficie. Hay dos clases de corteza: la oceánica y la continental. • Placas oceánicas. Están cubiertas íntegramente por corteza oceánica, delgada, de composición básica: hierro y magnesio dominantes. Aparecen sumergidas en toda su extensión, salvo por existencia de edificios volcánicos intraplaca, de los cuales los destacados por altos aparecen emergidos, o por arcos insulares (de islas) en alguno de sus bordes. Los ejemplos más notables se ubican en el Pacífico: la del Pacífico, la placa de Nazca, la placa de Cocos y la placa Filipina. • Placas mixtas. Son placas parcialmente cubiertas por corteza continental y así mismo en parte por corteza oceánica. La mayoría de las placas son de estas características.
