an important adjunct to the study of
Geography. So invest in one and go through it, carefully noting prominent
features-physical end economic, espe­cially of India. R~ember what lines represent on the map~

which the value of a particular phe­
'nomenon or product is uniform.
Isonoma/ Any line representing continu­
ous value on maps.
Isobars Lines of equal pressure.
Isobaths Lines of equal depth in the sea. Isobronts Lines joining places experienc­
ing a thunderstorm at the same time.
Isochrones Lines joining places located at
equal travel time from a common
centre.
Isogonals Lines joining places with the
same magnetic declination. Isohalines Isopleths of salinity. Isohels Isopleths of equal amount of
sunshine. Isohyet Isopleth of rainfall. Isohypse (Or contour lines) Isopleths of
elevation above sea level. Isonif Isopleth of amount of snow. Isophene Isopleth of seasonal phenom­
ena, e.g., the flowering dates of
plants. Isorymes Lines of equal frost. Isoseisma/s Lines of equal seismic activ­
ity.
