UNIDAD 2: CONTINENTES Y OCÉANOS

ACTIVITY 6: PLATE TECTONICS

 1. Read the following text:

The Earth's crust consists of a number of moving pieces or plates, that are always in motion. The Lithosphere consists of nine large plates and twelve smaller ones. The study of Tectonic plates helps to explain continental movement, volcanic eruptions and how mountains are formed. The high temperature inside the Earth move the mantle rock up to the surface. This cycle takes millions of years.

Continental movement:
The plates move across the surface of the Earth over millions of years. This changes the external appearance of the Earth. Look at the map of the world – the east coast of North and South America fits into the west coast of Europe and Africa! Millions of years ago, these continents were connected
