Elephants live in parts of Africa and Asia. They eat only plants, including grasses, leaves, and fruit that they collect with the trunk. They live in small family groups, or herds, led by adult females.
The Lunar Roving Vehicle, used on the Apollo 15, 16, and 17 missions. Built by Boeing largely of aluminum alloy, the vehicle was designed to carry two astronauts and their tools, instruments, and lunar samples up to a total payload of 490 kg (1,080 pounds), which was more than twice its own weight; nevertheless, it could be folded into a space 1.5 metres (5 feet) wide and 0.5 metre (20 inches) thick for stowage in the Lunar Module. Each steel-mesh wheel was driven by a small electric motor, which gave the rover a maximum speed of 12 km (8 miles) per hour on clear ground. Its large dish antenna transmitted a TV signal from a front-mounted colour camera directly to Earth.
Iguassu Falls, “an ocean plunging into an abyss” on the border between Argentina and Brazil. The waterfall system consists of 275 falls along 2.7 kilometers (1.67 miles) of the Iguassu River. Position is at latitude (DMS): 25° 40' 60 S, longitude (DMS): 54° 25' 60 W . Some of the individual falls are up to 82 meters (269 ft) in height, though the majority are about 64 metres (210 ft). The Garganta del Diablo (Devil's Throat; Garganta do Diabo in Portuguese), a U-shaped 82-meter-high, 150-meter-wide and 700-meter-long (490 by 2300 feet) cliff, is the most impressive of all, and marks the border between Argentina and Brazil. Two thirds of the falls are within Argentine territory. [1] About 900 metres of the 2.7-kilometer length does not have water flowing over it. The edge of the basalt cap recedes only 3 mm per year. The water of the lower Iguassu collects in a canyon that drains into the Parana River in Argentina, shortly downstream from the Itaipu dam.
