3.       If the advancing cold front is colder than the cool air mass of the warm front, the advancing cold front undercuts and lifts both the warm and cool air masses  of the warm front. This is

a.    Warm Occlusion

b.      Cold Occlusion

4.       The airmass which originated over land area located in polar region:

a.      Warm & dry

b.      Warm & Moist

c.    Cold & dry

5.       If a warm airmass overtakes a cold air mass, it is called

a.      Cold Front

b.    Warm Front

c.      Occluded Front

6.       At warm front

Precipitation

1.       When super cooled water drops and ice particles co-exist, the ice crystals grow at the expense of the water drops because
