The first manned expedition was in 1960 when Don Walsh and Jacques Piccard took the risk and became the first to conquer the Challenger Deep for about 30 minutes. Fifty-two years later, James Cameron seized the opportunity to dive solo into this chasm in a submarine he helped design. He sp...
flooding, and earthquakes have also damaged areas of forests. Nearly all countries in the tropics face at least forest degradation as result of the impact of human interventions in production forests, protected areas and parks. In many tropical countries, the climate appears to be changing. Recent...
North of this line is the subtropics and Northern Temperate Zone. The Tropic of Capricorn is at the opposite latitude south of the equator. The tropics, which includes the Tropic of Cancer, account for 36 percent of the Earth’s landmass and are home to about a third of the world’s pop...
Nearly all countries in the tropics face at least forest degradation as result of the impact of human interventions in production forests, protected areas and parks. In many tropical countries, the climate appears to be changing. Recent data provide evidence of, for example, increasing temperatures...
It is impossible to give a precise answer for a number of reasons, though generally as you move away from the tropics towards colder climates, there is a general reduction in the number of species, but increase of numbers of individuals of a species. So Antarctica has not so many different...
The temperatures in the world's oceans range widely. From -2°C/ 28°Fin the Arctic and Antarctic waters up to 28°C/ 82°Fin the Tropics. In general, ocean water is warmer closer to the shore and near hydrothermal vents. Due to climate change, ocean water temperatures rise is experienc...
or the Congo. Even within the tropics, rainforests have a great deal of variability depending on soils and geology, precipitation patterns, and even their resident wildlife (elephants can have a significant impact on forest structure by trampling seedings and creating meadows, for example). For th...
determined that forest area losses in the tropics were outweighed by gains elsewhere.[84] Species Extinction * In 2012, Eileen Crist, professor in the Department of Science and Technology in Society at Virginia Tech,[85] and Philip Cafaro, former president of the International Society for Envi...
This resulted in this line of latitude being named the Tropic of Capricorn. The name Capricorn itself comes from the Latin word caper, meaning goat and was the name given to the constellation. The tropics experience little difference between seasons so, between the Tropic of Capricorn and the ...
