The monsoon winds are known as the seasonal winds.
-
True
-
False
The monsoon is a seasonal modification of the general planetary wind system. Monsoon winds are most powerful India and China. During summer, the interior of Asia become hot and low pressure develops there. On the other hand, the water surface of Indian ocean remains cooler and the pressure gradient is towards the heated interior. So monsoon wind blows from water to land, it is moist and brings lots of rain. In winter the water is warmer than the land surface. As a result, the wind blows from the interior towards the ocean so it is cold and dry.
Wind rose consists of ______ made up of _________ compass points.
-
Octagon , 8
-
Hexagon, 6
-
Polygon, 2
-
None of these
Wind rose is a tool which gives us the idea of how typically the speed and direction of the wind are distributed at a particular location. It consist of 8 compass points.
What is Wind Rose?
-
Flower
-
Instrument to measure wind flow
-
Instrument to measure wind speed and direction
-
None of these
Wind Rose is the instrument to measure wind speed and direction of the wind. They help to identify the direction and frequency of wind in a particular place. One of the important use of Wind Rose in the construction of airport runways, so that the airplane can take the best takeoff and landing point towards and away from the wind.
Periodic wind blow during particular time of the _______ or __________.
-
Day, Year
-
Day , Month
-
Day , periods
-
None of these
The winds which change their direction periodically with the change in season are known as periodic winds. They blow at regular intervals. They blow during particular time of the day or year. Localized differences in pressure and temperature are the main cause of periodic winds. For example, land and sea breezes and the seasonal wands.
Days without any wind are recorded as _______.
-
Day of relax
-
Day of calm
-
Day of winter
-
None of these
A wind rose diagram summarizes information about wind at a particular location over a specific period of time. It gives the percentage of time for which the wind blows from each direction, the strengths of these winds and the percentage of time calm air or light winds are observed.
Wind is ________ movement of air.
-
Vertical
-
Horizontal
-
Both a and b
-
None of these
Wind is the horizontal movement of the air. The differences in air pressure within our atmosphere causes the wind. Under high pressure, air moves towards area of low pressure. The greater the difference in pressure, the faster the air flows. Wind is described with direction and speed. The direction from which the wind is blowing describes the direction of wind.
The horizontal movement of the air is called ___________.
-
Air current
-
Wind
-
Tides
-
Cyclone
- The horizontal movement of air is called wind, hence option B is correct.
- Air current involves both horizontal and vertical movement of air thus incorrect.
- Cyclone is a circular movement of air.
- Tides are the rise and fall of the sea level due to gravitational pull of moon and sun.
In which of the following the wind velocity is the highest?
-
Thunderstorm
-
Hurricane
-
Typhoon
-
Tornado
- Among the given options tornado has the highest wind velocity and the thunderstorm has the lowest wind velocity
- Hence tornado is the right answer.
The moist air cause winter rains in the north-western region of India are part of _______.
-
Trade winds
-
Westerlies
-
Local disturbances
-
Retreating monsoons
Westerlies,
What is meant by planetary winds?
-
Winds occurring on the planet throughout the year
-
Winds occurring on the planet in seasons
-
Winds occurring due to local variation in temperature and pressure
-
These are the winds which blow extensively over continents and oceans
