Every school boy knows about lava, but have you ever heard of pyroclastic flows? It's a lavaless emission from a volcano, and Nature's Forces of the Wild had some great footage of one of these huge clouds spilling down the mountain and spreading across the sea on a cushion of steam of its own making.
Another powerful image from episode 4- thousands of emus bunched up against a fence. El Nino causes droughts in Africa and Australia. The emus have to leave the interior of the continent to find water. Farmers fields have water, but hundred of miles of fence (erected to keep dingos out) separate the emus from their goal.
