Chosen subject - Earthquakes

The Wonders of Nature brief listed these as the optional topics:

Mountains, Rivers, Glaciers, Deserts, Forests, Antarctica, The Arctic, Canyons, Volcanoes, Earthquakes, Storms, Monsoon, Reefs, Oceans, Migration, Plains & Grasslands.

I had an option of about 6 of these due to being number 10 in the queue of choosing them. Which were I think Glaciers, Canyons, Earthquakes, Monsoons, Plains & Grasslands and forgotten the other one.

Earthquakes interested me the most out of all these subjects and gave me the best visualisations when thinking about all of them which is why I picked this as my topic.
