Context: Read the passage and look at the picture.
The Alpine Fault runs the length of New Zealand’s South Island, marking a boundary between the Pacific Plate and the Indo-Australian Plate. As the two plates slide past each other, the Pacific Plate is being pushed up higher than the Indo-Australian Plate. So, the mountains above the Pacific Plate have higher elevations than the mountains above the Indo-Australian Plate.
In the picture, you can see snow on the high mountains of the Pacific Plate. The Indo-Australian Plate, which is at a lower elevation, has much less snow.
