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.
Abyssal zone. The abyssal zone or abyssopelagic is a layer of the pelagic zone of the ocean. Abyss derives from the Greek word á¼Î²ÏÏÏÎ¿Ï, meaning bottomless. At depths of 4,000 to 6,000 metres (13,123 to 19,685 feet), this zone remains in perpetual darkness and never receives daylight.
