The maximum amount of water vapor air can hold at a given temperature is called the vapor pressure. dew point. absolute humidity. saturation point.

## Step 1
The problem is asking for the term that describes the maximum amount of water vapor that air can hold at a given temperature. This is a concept in meteorology, a branch of geography.

## Step 2
The term 'vapor pressure' refers to the pressure exerted by a vapor in thermodynamic equilibrium with its condensed phases at a given temperature. This term does not describe the maximum amount of water vapor that air can hold.

## Step 3
The 'dew point' is the temperature at which air becomes saturated with water vapor, leading to the formation of dew. This term does not describe the maximum amount of water vapor that air can hold.

## Step 4
'Absolute humidity' is the total mass of water vapor present in a given volume or mass of air, usually expressed in grams per cubic meter. This term does not describe the maximum amount of water vapor that air can hold.

## Step 5
The 'aturation point' is the maximum amount of water vapor that air can hold at a given temperature. When the air is saturated, it cannot hold any more water vapor, and any additional vapor will condense out. This term accurately describes the maximum amount of water vapor that air can hold at a given temperature.
