Yr13 - Tectonics

Those of us who were here on Wednesday reminded ourselves about the structure of the earth and talked about plate tectonics theory.

You then put some nice maps together showing the major tectonic plates and the directions in which they are moving.

For the next time I see you, you need to be finding out about the main types of plate margin:

Destructive (convergent) - oceanic/oceanic, oceanic/continental, continental/continental

Constructive (divergent)

Conservative

For each, you need to be thinking about processes and landforms, you need a named/located example, and you need a diagram.

You might also like to check out the post on Geogtastic about Hunga Ha'apai, the underwater volcano near Tonga that erupted earlier in the week - some spectacular photos about, and also check out the Smithsonian Global Vulcanism and USGS Earthquake Monitoring overlays in Google Earth.
