Answer 2

(i) If the surface air pressure is 1,000 mb, the air pressure at 1 km above the surface will be:

The air pressure decreases by 1 mb for every increase bof 10 m in height

Since, height increased = 1 km

Air pressure decrease by units = 1000/10 = 100 units

Hence, pressure at 1 km above will be

1000 - 100 = 900 mb

ii) The Inter Tropical Convergence Zone normally occurs:

Near the equator

iii) The direction of wind around a low pressure in northern hemisphere is:

Anti-clock wise

iv) The source region for the formation of air

masses is :

Siberian plain
