Humidity and Dew Point

Dew Point is the

• temperature air cools down to reach condensation (or turn into a liquid)
• temperature where ice melts to liquid water
• temperature where ice turns directly into water vapor
• time of day when dew on the ground disappears

If the air is "saturated", that means:

• the air is full of water
• the air is partially full of water
• it's amount of water vapor in the atmosphere right now
• how much liquid water it potentially can hold

Water vapor is one of the components of the air in the atmosphere.  What change causes the vapor in the air to form clouds?

• A.  As air rises in the atmosphere, it becomes warmer and cannot hold as much water. 
• B. As air cools, water vapor in the air condenses to liquid or solid state. 
• C. Air rises, the water becomes heavier and changes form.

As the air temperature increases, the air's capacity for water vapor: 

• increases
• decreases
• remains the same
• is unrelated to air temperature and can either increase or decrease

The temperature to which air must be cooled in order to become saturated is the: 

• Relative Humidity
• Mixing Ratio
• Dew Point Temperature
• Wet-bulb Temperature

Which environment will probably have the lowest relative humidity?

• swamp
• desert
• rain forest

What kind of air describes "humid" air? 

• warm and wet 
• cold and dry
• cold and wet
• warm and dry

If the dew point temperature and the actual air temperature are similar, are clouds and precipitation MORE LIKELY or LESS LIKELY than if the two temperatures are very different.

• More Likely

• Less Likely
