Geography [1 Mark Question Answer]

The rate of decrease of temperature is 1°C for every 166 meters, the temperatures on a mountain are lesser than the temperatures on a seashore which is nearly at zero height

Torrid zone, Temperate zone and Frigid zone.

Heat balance is defined as the state of equilibrium that exists on earth between incoming insolation from the sun and the out going terrestrial radiation from the earth.

 It is the difference between mean maximum and mean minimum temperatures within a year, mainly between June and January.

It is the difference between the mean maximum and mean minimum temperatures within the month.

Diurnal range is the difference between the maximum and minimum temperature within 24 hours, of the day.

Medium temperature and medium rainfall due to slanting rays of the sun and less evaporation.

Only 51% of the insolation reaches the earth’s surface because 35% is reflected back into space by the atmospheric layers and 14% is absorbed by the atmosphere.

Mumbai has an equable climate due to coastal location, while Delhi is an inland town. The presence of land and sea breezes keep the nights warm at Mumbai.

Out of 100 units, only 51 units are received by the earth as isolation, while 35 units are reflected back by atmospheric layers, clouds, snowfields, and 14 units are absorbed by the ozone layer.

As the rays of the sun become more and more slanting with increasing latitudes. So the tropical region never gets snowfall, while the polar region is always frozen.

The warm effect of the sea keeps the temperature less in summer and higher in winter, e.g. Bombay (Mumbai) is warmer than Delhi in winter.

Delhi is far from the sea, while Chennai is situated along the coast of Bay of Bengal. So Delhi is colder than Chennai in December
