please explain me variations in pressure due to atmosphere and all other essential principles on which pressure works? how tides are influenced due to pressure..?
AND,
ALSO TELL ME ABOUT,, triboelectric series..how does that work?/

The air pressure is the pressure exerted by a vertical column of air in the atmosphere on unit area. So, places where atmospheric air mass is more will have higher air pressure in that region.
Similarly, places where atmospheric air mass is less will have less air pressure in that region.
 
Also, as we go up in the atmosphere, there is less air above that elevation. So, the atmospheric pressure decreases as we go higher in the atmosphere.
 
Now, if air pressure is more on a particular area of the sea, then the height of tides will be reduced. Similarly, if the air pressure is small then the height of the tides is increased from their standard level.
 
NOTE: Triboelectric series is not included in the grade 11/12 syllabus. However, if you still want to find out about it, then you can browse the internet for information regarding the same.
