Teaching notes. mass x specific thermal capacity x temperature / time = current (amps) x p.d. The ratio temperature rise / time can be obtained from the slope of a graph of temperature plotted against time. 2 The aluminium blocks can be lagged by enclosing them in foamed polystyrene.
An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earthâs surface. They are among the flattest, smoothest and least explored regions on Earth.
The Great Rift Valley is part of an intra-continental ridge system that runs through Kenya from north to south.It is part of the Gregory Rift, the eastern branch of the East African Rift, which starts in Tanzania to the south and continues northward into Ethiopia.ake Turkana occupies the northern end of the Great Rift Valley in Kenya. There are also volcanoes in Lake Turkana. The Suguta Valley, or Suguta Mud Flats, is an arid part of the Great Rift Valley directly south of Lake Turkana.
