Varying between 0 to 100mm per year, the movement of a plate is driven by convection in the underlying hot and viscous mantle. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries in zones that may be anything from a few kilometres to a few hundred kilometres wide. To watch a simulated fly-by along New Zealand's plate boundary check out this video.
The average business card size in cm (centimeters) is 8.9 x 5.1. In inches this is 3.5 x 2. In millimeters (mm) the size will be 88.9 x 50.8. Measurements are usually given in inches or millimeters.
For most ID cards and credit cards, ID-1 from the ISO/IEC 7810 (Wikipedia) standard gives the dimensions, which are 85.60 Ã 53.98 mm (3.370 Ã 2.125 in) with an aspect ratio of 1.586. This is also the standard business card size in many situations as it is highly pocketable. Another size which could be considered somewhat international, is the ISO 216-sized (Wikipedia) A8 = 74 x 52 mm (2.913 Ã 2.047 in) with an aspect ratio of 1.423. Though, personally, I haven't seen many of these.
