...areas, particularly in the forests of the south and southwest, an almost impenetrable thicket known as horizontal scrub develops. This is caused by the growth of a remarkable small tree called the horizontal (Anodopetalum biglandulosum). The slender trunk of the tree falls over under its own weight, and from it branches arise that behave in the same way. On the mountain plateaus are...

In the conventional arrangement the elevator, attached to the horizontal stabilizer, controls movement around the lateral axis and in effect controls the angle of attack. Forward movement of the control column lowers the elevator, depressing the nose and raising the tail; backward pressure raises the elevator, raising the nose and lowering the tail. Many modern aircraft combine the elevator and...

...or groups through a system of social hierarchy or stratification. If such mobility involves a change in position, especially in occupation, but no change in social class, it is called “horizontal mobility.” An example would be a person who moves from a managerial position in one company to a similar position in another.

Horizontal resistance, on the other hand, protects plant varieties against several strains of a pathogen, although the protection is not as complete. Horizontal resistance is more common and involves...
