What will happen after high speed winds blow ?
Air pressure will increase
Air pressure will decrease
water vapour will be formed
static electricity will be generated
Why wind currents are generated ?
Uneven heating between the equator and the poles
Uneven heating between Artic and Antartic continents
Due to thunder storm
Due to cyclone
What happen when water vapour changes back to liquid in the form of raindrops ?
Heat is absorbed
Heat is released
Heat is first absorbed and then released
there is no exchange of heat.
