Transform Faults model - video

Have you tried to make last week's model of spreading ocean ridges offset by transform faults? This video will show you what the model should look like.
This is one of many video clips produced to demonstrate activities in the Earth Energy category.

Make a model to demonstrate transform faults

Transform faults are difficult for pupils to understand. Making this model will help them to see how these faults offset spreading ocean ridges and also offset the magnetic 'stripes'. Click here 'Model a spreading ocean floor offset by transform faults' for this latest free ELI+ activity. Transform faults are one of the three types of plate boundaries and are also called 'conservative plate margins'. The other two types are the constructive/divergent plate margin that form oceanic ridges and destructive/convergent plate margins where plates are subducted. Just look in the Earthlearningidea Keyword Index to find activities about all of these plate margins.

NEW - Continents in collision

How did the Himalayan mountains form? Why can you find marine fossils in the rocks at the top of these mountains? Try making this simple model to find out and to explain continents in collision. This latest ELI+ activity models the processes which occur at destructive (convergent) plate margins.
There are many other simple demonstrations to model Earth processes on our website.
