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.
And the word 'plain' usually means a flat, wide area. Put those two things together and you have an abyssal plain, which refers to the huge, flat areas on the ocean floor. Flat is almost an understatement. The abyssal plains are some of the flattest features on the planet.Some drop in elevation less than a foot for every 1,000 feet in distance.f you have no idea what an abyssal plain is, your imagination is likely to come up with some depressing images ('abyssal' sounds pretty close to 'abysmal,' after all). Here you will learn what an abyssal plain actually is, what it looks like and what lives there.
