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.
Largest Alluvial Plain of the World. The Great Plain of North India also known as Indo-Gangetic-Brahmaputra Plain is the largest alluvial plain of the world. This arcuate plain extends for a length of 3200 km from the mouth of the Indus to the mouth of the Ganga. The plain lies partly in Pakistan and partly in India. The length of the plain in India is around 2400 km. The average width of the plain varies from 150 to 300 km.
