The statement that the saturation vapor pressure of the air parcel increases is true among the given statements.
Answer: Option B
<u>Explanation:</u>
The saturation vapor pressure of the air parcel will increase with the increasing temperature. The amount of pressure that each air bubble will exert will increase if the temperature is increased. This would in turn make the vapor molecules saturate just above the water molecules.
This eventually results in precipitation. At high temperature, vapor molecules take less time to saturate over the water as compared to saturation at freezing temperatures which means that rainfall is more when temperature causes saturation vapor pressure to increase.
The correct answer is - a rise in the total amount of goods and services produced within the borders of a nation.
The economic growth is is defined by the economic activity of the nation, how much is it producing, as well as the quality of the production, of both goods and services within its borders.
