Q1.
In your Grade 6 Science textbook ‘Curiosity’ you studied the water cycle! “The water from the ocean and the Earth's surface evaporates into the atmosphere as vapour and returns as rain, hail or snow….”
Answer
Recalled, and here is why it is put in this chapter. The water cycle is the machinery behind everything the section on winds says.
Water leaves the sea as vapour, wind carries it over the land, and it comes back down as precipitation. Without the wind in the middle, the water would simply fall back into the sea.
The three steps, and what each has to do with wind:
Evaporation — water leaves the ocean and the Earth's surface as invisible vapour. This is why a wind that has just crossed the sea is a moist wind, and a wind that has crossed the deserts of Arabia and Afghanistan is a dry one.
Transport — the wind carries that vapour over the land. Winds affect not only temperature but also humidity, and in turn precipitation.
Condensation and return — the vapour condenses into clouds and returns as rain, hail or snow.
Why this matters for the next section: the monsoon is nothing but this cycle running on a giant scale and on a yearly timetable. Sea winds pick up moisture, the hot Indian land makes them rise and cool, and the water comes down as the monsoon rain. Recall the cycle and the monsoon stops being mysterious.
