Lesson 7 Pre-Quiz Meteorology

What is the ISA Standard Lapse Rate for atmospheric pressure?

• 2 Hg per 3,000 feet.

• 1 Hg per 1,000 feet.

• 1013.25 mb.

• 2°C per 1,000 feet.

If the actual air temperature at a given moment over a given place at 10,000' MSL is +5°C, is this considered to be standard temperature, colder than standard, or warmer than standard? Is this air more dense, less dense, or is there no change from the standard air density at 10,000' MSL?

• Warmer than standard temperature and more dense.

• Warmer than standard air temperature and less dense.

• Colder than standard temperature and less dense.

• Colder than standard air temperature and more dense.

In what layer of the atmosphere does almost all of our weather occur?

• Tropopause.

• Stratosphere.

• Troposphere.

• Mesosphere.

At roughly what altitude is air pressure about half of what it is at sea level?

• 10,000 feet.

• 13,500 feet.

• 18,000 feet.

• 10,500 feet.

On a warm, sunny afternoon, the very shallow layer of air that is immediately in contact with the earth's surface is warmed by the earth's surface by a process called

• Conduction.

• Convection.

• Radiation.

• Advection.

Which of the following is not one of the standard units of air pressure?

• Hectopascal.

• Millibars.

• Inches of Mercury.

• All the above unites are used to measure air pressure.

This temperature scale is mostly used in scientific experiments and does not contain negative values.

• Kelvin.

• Fahrenheit.

• Celsius.

• Newtons.

Surface temperature inversions normally occur during

• Mid-day when the sun is at its highest point.

• The night when the sky is overcast and there are high surface winds.

• The night when there are clear skies with no surface winds.

What is the primary source of water for evaporation in the atmosphere?

• Rivers.

• Lakes.

• Oceans.

• Groundwater.

Which phase transition involves water changing directly from a gas to a solid without passing through the liquid phase?

• Evaporation.

• Condensation.

• Sublimation.

• Deposition.
