Objetivos de aprendizaje

Al final de este capítulo deberías ser capaz de:

Describir la teoría de la tectónica de placas y la evidencia utilizada para apoyarla.
Compara y contrasta la configuración ambiental de los cuatro tipos de límites de placa.
Explicar la relación entre sismos, volcanes y límites de placas.
Dibuje diagramas simples que muestren el efecto de la tensión en los materiales rocosos.
Describir el movimiento asociado con fallas.
Describir las características de accidentes geográficos resultantes del plegado.

In this chapter you'll travel back to a distant time when the geography of the Earth's crust was much different than it is today. The search for answers to Earth's dynamic nature will set the context for explaining modern day tectonic activity. Tectonics is study of the processes that control the structure and properties of Earth's lithosphere. Plate tectonics is the process of plate formation, movement, and destruction. It explains the evolution of Earth's surface through time, the building of mountains, formation of deep valleys, and the movements of lithospheric plates that have impacted climate, human evolution and the distribution of plant and animal species. By the conclusion of the chapter you should be able to explain how plate movement has created many of the surface features of our present day Earth.
