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.
Most of the ocean floor is a huge, dark, nearly flat area called the Abyssal Plain. The sea floor is a huge flat area. It lies at depths of about 4000 to 6000 meters below the surface of the ocean. It is called the Abyssal Plain. Sea floor spreading occurs here, which means that there is volcanic action and a mid-ocean ridge where some of the lava has cooled.
