Opposite: The orogeny that created the Himalayas <strong>and</strong> the<br />
Tibetan Plateau was (<strong>and</strong> still is!) caused by the collision of<br />
India with the Eurasian Plate (Source: http://en.wikipedia<br />

The image below was captured by the<br />
International Space Station in 2004. It shows the<br />
Himalayan mountain belt with the Tibetan<br />
Plateau in the foreground. (Source of image:<br />
http://en.wikipedia.org/wiki/Image:Himalayas.jpg)<br />
. Four of Earth’s 8000-plus metre peaks are<br />
shown in this image, including Mt Everest at<br />
8850 m, the highest.<br />
The diagram below shows that when a mountain range is formed by orogenic<br />
activity, regional metamorphism of ever-increasing grade is associated with<br />
increasing severity of folding of the rocks.<br />
