ITCZ) or equatorial trough. This line of convergence near the equator is also discernible in a map of streamlines (Figure 12.2; Note 12.A). It is actually a band a few hundred kilometres wide, enclosing places where winds flow inwards (are 'confluent') and subsequently rise convectively.he movement of the ITCZ across South Africa (Figure 12.1) is complicated by the land's shape, elevation and location, and there is a southerly spur called the Zaire Air Boundary (ZAB). Similarly, there is a spur over South America.

With both normal and reverse faults, movement occurs vertically. A normal fault is usually associated with plates that are diverging. Tension weakens the crust until the rock fractures, and one block of rock moves downward relative to the other. A reverse fault is usually associated with plates that are colliding. Compression forces a fault block upward. A thrust fault is a special kind of reverse fault where one or more plates are under the ocean. At a thrust fault, a plate below the sea is moving under another plate, thrusting its edge upward. The process of one plate diving under the other is called subduction. Thrust faults can produce larger earthquakes than strike-slip faults.
