how does the wind vane tell us about the direction of wind flow?
the weather vane consists of a pointed with a large rear end . moving air exerts pressure on the arrows and the pointed arrow shows direction of wind flow . it helps us to identify...
explain how is wind created
wind is caused due to the heat of the sun . when a place gets heated by the sun the air above it also becomes hot .the hot air being lighter than the surrounding cold air. it moves...
what happens when the person blows the air between the balloons
the low pressure is created between the two balloons . the high pressure outside the balloon is more making the balloons to come closer to each other
why are high speed winds always accompanied with reduced air pressure explain giving reason
a ir exerts pressure on all the things . when high speed winds are blown they blow off the air from that area thus creating a low pressure in that area . a low pressure is caused when...
why are roof blown of during storms .draw a diagram and explain it
whe the high speed  winds are  blown during storms it blows the wind thus creating low pressure on the roof and under the roof the air exerts high pressure . this imbalance...
pressure difference between two points causes wind to flow .is this statement correct?give reason to support your answer
the more the difference between the two points the faster is the wind flow .as the pressure increases the velocity also increases
explain with a diagram the reason for wind circulation on the earth's surface
the wind always move from high pressure to the low pressure region . the temperature near the equator is high than near the poles . this is due to the direct sunlight received by the...
what is tornado?how is it different from a cyclone?
tornado is the most violent small scale storms on earth it is mostly formed on the land . it proceeds in a rotating column and extend from the surface to the thunder cloud.it is not...
1.    which states of India should  take preventive measure and why?
Indian has coastline on its east and west side. the states lying on theses coastlines are vulnerable to cyclones and cyclones.it has been observed that the  east coast of...
1.    list some personal safety measure during thunderstorm
1.     always stay inside your houses during storms,do not go outside for fun 2.     secure windows and doors and stay away from them 3.    ...
1.    why does the fertility of soil reduce in a cyclone affected area?
The flood water contain alkaline in it.when it enters the farmland it affects the fertility of the soil.  
1.    the advancement of scientific technology help us to take action against...
It is true because now a dys satellites and radar keep track of the information and movement of cyclones and thunderstorm.  warnings are issued well in advance so that people...
1.    list three disastrous consequences a cyclone can have?  
Cyclone kill hundreds of people living in coastal areas.it affect the fertility of the soil because the flood water contain alkaline  that enters the farmland The...
1.    what is IMD?
It means Indian meteorological department. It provides current and forecast information for weather sensitive activities like agriculture , irrigation , shipping etc.it also...
1.    explain with examples how wind exerts pressure on various things?
If we keep a heavy object on our palm we feel it is giving pressure on our palm.if we can swim we know that the pressure of water on our body increases as we go deeper.similarly...
1.    describe with some activities that high speed  winds are always accompanied...
Hang two blown up balloons on a stick at a distance of about 10 cm from each other . now forcefully blow out air from your mouth between the two balloons.you will notice that...
1.    what are the problem faced by the the people living in cyclone prone areas?
  The vegetation is effected by the cyclone because of the alkaline flood waters.the transport system is also badly affected.it causes enormous damages to the people’s...
1.    how does wind vane tell us about the direction of wind flow ?
the weather vane consists of a pointed arrow with a large rear . moving air exerts pressure on the arrows and the pointed arrow shows direction of wind flow. It helps us to identify...
1.    explain how is wind created?
Wind is caused due to the heat of  sun . when a place is heated by the sun the air becomes hot. Hot air being lighter than the surrounding cold air moves up . to fill...
1.    why are high speed winds always accompanied with reduced air pressure explain...
air exert pressure on all the things. when high speed winds are blown they blow off the air from that area thus creating a low pressure in that area . a low pressure is caused...
1.    why are roof blown of during storms . draw diagram and explain it ?
under the roof air exerts pressure and on top of the roof  there is low pressure because of  the high speed wind which carries away some amount of air with it . the...
1.     pressure difference between two points causes wind to flow . is this statement correct ? give reason to support...
It is correct  because the more the difference between the two points the faster is the wind flow . as the pressure increases the velocity also increases.  
1.    explain with a diagram the reason for wind circulation on the earth’s...
the wind always move from high pressure region to the low pressure region . the temperature near the equator is high than temperature near the poles . this is due to the direct...
