Question

Distinguish between Isobar and Isotherm.

Answer 1

Difference between isobar and isotherm:-

Isotherms:

1. They are imaginary lines drawn on the map joining places hav­ing the same temperature when reduced to sea level.

2. Closely spaced isotherms indi­cate great range of temperature.

3. The unit of measurement is de­gree (°C) Celsius or Fahrenheit.

Isobars:

1. They are imaginary lines drawn on the map joining places hav­ing the same atmospheric pres­sure when reduced to sea level.

2. Close spacing of the isobars means steep rise/fall in pressure.

3. The unit of measurement is in millibars (mb).
