State whether the following statements are True or False: (i) If wind flows from land to the ocean, then it is daytime. (ii) A very high-pressure system, with very high-speed wind surrounding it forms a cyclone. (iii) The coastline of India is not vulnerable to cyclones. (iv) Warm air is lighter than cool air.

Soln:

(i) False- if the wind blows from land to the ocean, then it is night time because, at night, the water cools down more slowly than the land. So, the cool wind from the land moves towards the ocean.

(ii) False – a very low-pressure system, with very high-speed winds revolving around it, forms a cyclone.

(iii) False- the whole coastline of India is vulnerable to cyclones, particularly the east coast.

(iv) True
