The Palghat Gap is a wide trough about thirty kilometres across, and it is the principal natural break in the otherwise continuous wall of the Western Ghats.

Both rivers flow westward along faulted troughs, or rift valleys, that lie between the Vindhya and the Satpura ranges, and both empty into the Arabian Sea through estuaries instead of deltas.

Anaimudi stands in the Anaimalai hills of Kerala, where the Anaimalai, Palani and Cardamom hills meet, and rises to about 2,695 metres.

Where the rivers leave the hills they drop their coarsest load, and the resulting belt of gravel and pebbles is so porous that the smaller streams sink into it and vanish.

Lakshadweep is a group of small coral islands, atolls and reefs lying off the Malabar coast of Kerala in the Arabian Sea, built on a submarine ridge.

The resistance of a wire equals the resistivity of the material multiplied by the length and divided by the area of cross section.

It is the energy consumed by an appliance of one kilowatt working for one hour, and it equals three point six million joules.

The tangent drawn to a magnetic field line at any point gives the direction of the field at that point.

The fuse is a short piece of wire of low melting point placed in series in the live line, so that an excessive current melts it and breaks the circuit.

In 1831 Faraday showed that when the magnetic flux linked with a closed coil changes, whether by moving a magnet, moving the coil or changing the current in a nearby coil, a current is induced in it.

In Fleming's left hand rule the forefinger, the middle finger and the thumb of the left hand are held at right angles to one another: the forefinger points along the magnetic field, the middle finger along the current, and the thumb then gives the direction of the force.

Hold the conductor in your right hand with the thumb stretched along the direction of the conventional current; the way your fingers curl round the wire is the direction of the concentric magnetic field lines.

Tungsten has the highest melting point of all metals, well above three thousand degrees Celsius, so a thin tungsten wire can be heated until it glows white without melting.

By Ohm's law the resistance equals the potential difference divided by the current. Here the current must first be converted into the base unit: two milliampere is 0.002 ampere.

A microwave oven does not cook by passing a current through a resistance. It generates microwaves in a magnetron, and these waves make the water molecules in the food rotate rapidly, so the food heats from within by dielectric heating.

The potential difference between two points in a circuit is defined as the work done in moving a unit positive charge from one point to the other.

By Ohm's law, at a constant temperature the current through a conductor is directly proportional to the potential difference across its ends, since the current equals the potential difference divided by the resistance.

Set up in 1981 and based at Dehradun, it assesses the country's forest and tree cover from satellite data and brings out the India State of Forest Report once every two years, giving the cover state by state and by density class.

The Montreal Protocol was adopted under the Vienna Convention of 1985 and sets a timetable for phasing out chlorofluorocarbons, halons and similar chemicals.

The convention was signed in 1971 at Ramsar, a town in Iran, and is the oldest of the modern global conservation treaties.
