Answer 1

Answer:

Hey mate hope it is helpful

Explanation:

in brief, the variation in atmospheric pressure with altitude?

Answer-Pressure variation with altitude - result

At a certain height above sea level, the weight of column of air above that height will be lesser than sea level. So pressure due to column of air decreases as height increases.

Do

changes in temperature also cause a change in atmospheric pressure?

Yes. Temperature cause a change in atmospheic pressure. For example, If a place over the Earth's surface is heated more,the air above the place becomes warm ,rises and expands.So the density of the air becomes less leading to the reduction of the atmospheric pressure.
