. The East African Rift Zone and the Basin and Range areas in North America are examples of normal faults. Reverse faults refer to those fault lines that result from blocks of crust sliding above each other rather than separating from each other. The crust overlies the solidified and uppermost layer of the mantle.

An upsurge of matter from deep beneath the Earths crust could be pushing the continents of North and South America further apart from.
