Question

4. A region having low temperature gives rise to
a. low-pressure region.
b. high-pressure region.
C. strong wind.
d. gentle breeze,
5. Air pressure decreases with
a. decreasing altitude,
b. increasing altitude.
c. does not change at all.
d. both (a) and (b)​

Answer 1

A region having low temperature gives rise to high pressure zone.

The atmospheric pressure is referred to the weight of the air molecules in a specific volume. - Now,in the lower temperature,the density of the air increases and the weight in a specific area also increases due to higher density value.

Increasing Altitude

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

So, as we go up at higher altitude the pressure decreases.
