A transparent surface coating which is applied as a liquid and then changes to a hard solid.

A transportation vehicle, also called a hovercraft, that rides slightly above the Earth's surface on a cushion of air. The air is continuously forced under the vehicle by a fan, generating the cushion that greatly reduces friction between the moving vehicle and the surface. The air is usually delivered through ducts and injected at the periphery of the vehicle in a downward and inward direction. The design of the vehicle's underside, combined with seals or skirts attached below the hull around the perimeter, restrains the air, creating the cushion. Because the vehicle is not in contact with the surface, it has six dimensions of motion.

A tree (<i>Mangifera indica</i>) of the family Anacardiaceae that originated in the Indo-Burma region and is now grown throughout the tropical and subtropical areas of the world. The mango is a medium to large evergreen tree; it produces a dense, round canopy, with leaves up to 15 in. (38 cm) long by 2.5 in. (10 cm) wide, which are reddish brown when young and dark green when mature. The tree puts down a deep taproot and has many fibrous roots near the surface. Small, pinkish-white flowers, numbering 600 to 2000 and mostly staminate (male), grow on large terminal panicles.

A tree belonging to the genus <i>Nyssa</i> of the sour gum family, Nyssaceae. The most common species is <i>N</i>. <i>sylvatica</i>, variously called pepperidge, black gum, or sour gum, the authorized name being black tupelo. Tupelo grows in the easternmost third of the United States; southern Ontario, Canada; and Mexico. In moist soil this tree usually ranges from 60 to 80 ft (18–24 m) in height and 2 to 3 ft (0.6–0.9 m) in diameter, but some may be 110 ft (33 m) tall and 5 ft (1.5 m) in diameter.

A tree, <i>Guaiacum sanctum</i>, also known as holywood lignumvitae, which is cultivated to some extent in southern California and tropical Florida. Lignumvitae is native in the Florida Keys, Bahamas, West Indies, and Central and South America. It is an evergreen tree of medium size with abruptly pinnate leaves. The tree yields a resin or gum known as gum guaiac or resin of guaiac which is used in medicine. The very heavy black heartwood is used in bowling balls, blocks and pulleys, and parts of instruments.

A tree, <i>Liriodendron tulipifera</i>, also known in forestry as yellow poplar, belonging to the magnolia family, Magnoliaceae. One of the largest and most valuable hardwoods of eastern North America, it is native from southern New England and New York westward to southern Michigan, and south to Louisiana and northern Florida. In rich, moist soil it may grow 150 ft (45 m) tall and have a diameter of 8–10 ft (2.4–3 m).

A tree, <i>Pistacia vera</i>, of the Anacardiaceae family. It is native to central Asia and has been grown for its edible nuts throughout recorded history in Iran, Afghanistan, and Turkey and various other countries of the Mediterranean region. Extensive areas in the Sacramento and San Joaquin valleys of California were planted to pistachios in the 1970s, and the first commercial nut crop was harvested in 1977.

A tropical and subtropical fruit tree, <i>Persea americana</i>, in the Lauraceae family (containing also the laurel of antiquity and the trees that yield commercial cinnamon and camphor). It originated in Central America or adjoining regions of North or South America. It has now spread to much of the near-tropical world.

A tropical cyclone whose maximum sustained winds reach or exceed a threshold of 74 mi/h (119 km/h). In the western North Pacific Ocean it is known as a typhoon. Many tropical cyclones do not reach this wind strength.
Industry:Science
A tropical evergreen shrub or small tree of the genus <i>Coffea</i> (Rubiaceae), a native of northeast Africa and adjacent southwest Asia. The beverage known as coffee is made by the hot-water extraction of solubles from the ground roasted beans (seeds) of the shrub. <i>Coffea</i> grows mainly between the Tropic of Cancer and Tropic of Capricorn at elevations of 2000–6000 ft (600–1800 m) above sea level, at temperatures near 70°F (21°C), and with annual rains near 60 in. (150 cm).
