10. Islands forming in the Caribbean Sea

12. Plates move towards each other Subduction – the heavy plate goes under the lighter plate and pushes it up. Subduction – the heavy plate goes under the lighter plate and pushes it up. This forms high mountains that are often volcanic. This forms high mountains that are often volcanic. An example of this is the Himalayan Mountains An example of this is the Himalayan Mountains

13. Plates move side by side The land crumples to form low mountains (often volcanic) An example of this type of movement is the San Andreas fault in California. It is also why Baja California is separated from mainland Mexico. (see page 588)
