Describing Weather

What is humidity?

• Water, in liquid or solid form, that falls from the atmosphere.

• The atmospheric conditions, along with short-term changes, of a certain place at a certain time.

• The amount of water vapor in the air.

• The force that a column of air applies on the air or a surface below it.

________________ is the pressure that a column of air exerts on the surface below it.

• Air pressure

• Dew point

• Precipitation

• Condensation

Which of the following is not a variable used to describe the weather?

• Humidity

• Temperature

• Altitude

• Wind speed

• The average kinetic energy of the air molecules is very low.

• The average electrical energy of the air molecules is very high.

What happens to air pressure as altitude decreases?

• It increases

• It decreases

• It goes away completely

• It is transferred into precipitation

Which instrument is used to measure air pressure?

• Thermometer

• Anemometer

• Graduated cylinder

• Barometer

What is the difference between humidity and relative humidity?

• Relative humidity compares the actual humidity to the amount of water vapor the air could hold at the given air pressure.

• Humidity compares the relative humidity to the amount of water vapor the air could hold at the given air pressure.

• Relative humidity compares the actual humidity to the amount of water vapor the air could hold at the given temperature.

• Humidity compares the relative humidity to the amount of water vapor the air could hold at the given temperature.

Which kind of cloud is shown in the picture?

• Stratus Clouds

• Cumulus Clouds

• Cirrus Clouds

• Google Clouds

What is the difference between snow and sleet?

• Sleet solidifies as it falls and snow solidifies in the clouds.

• Sleet is a liquid and snow is a solid.

• Sleet is made of a different molecule than snow.

• Sleet is a solid and snow is a liquid.

What is fog?

• The series of natural processes by which water continually moves among oceans, land, and the atmosphere.

• A suspension of water droplets or ice crystals close to or at Earth's surface.

• Small droplets surrounded by thousands of other droplets that block and reflect light.

• Water, in liquid or solid form, that falls from the atmosphere.
