CBM Exam Practice Questions with 100% Correct Answers Graded A+. Which of the following best explains how pressure decreases with height in the Earth's atmosphere? A. It decreases at a constant rate (linear) B. It decreases quickly at first then more gradually (Exponential) C. It decreases at a rate 9.8 mb/km D. It decreases in the troposphere, increases in the stratosphere, then decreases to the top of the atmosphere - Answer- B. It decreases quickly at first then more gradually (Expon...

APES Unit 5: Climate and Land Use Layers of the Atmosphere - correct answer troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere Troposphere - correct answer Closest layer to Earth Densest layer Weather occurs Stratosphere - correct answer Ozone layer: pale blue gas composed of molecules made up of three oxygen atoms (O3) Absorbs UV-B and UV-C radiation Climate varies in different parts of the Ear...

CTS - Aviation Weather Theory Questions and Answers Graded A+ Standard Atmosphere was created by: Averaging conditions to create an idealized atmosphere. The standard temperature lapse rate in the lower layers of the atmosphere is: A decrease of 2° C per 1,000'. If the air temperature is +8°C at an elevation of 1,350 feet MSL and a standard (average) temperature lapse rate exists, what will be the approximate freezing level? 5,350 feet MSL. Moving up in the atmosphere, unsatur...

Private Pilot Vocab 100% Correct Absolute Altitude Actual height above the surface of the earth, either land or water. Absolute Ceiling The altitude where a particular airplane's climb rate reaches zero. Adiabatic Cooling A process of cooling the air through expansion. For example, as air moves up a slope it expands with the reduction of atmospheric pressure and cools as it expands. Adiabatic Heating A process of heating dry air through compression. For example, as air moves down a slope it ...

Chapter 2, Lesson 3: Aviation Weather Questions and Answers (Certified Solutions) What allows small vertical movements to grow until they produce turbulent airflow and air circulation? An unstable atmosphere How does adiabatic heating heat dry air? Through compression How does adiabatic cooling cool dry air? Through expansion Where does the adiabatic process take place? In all upward and downward moving air What happens when air rises into an area of lower pressure? It expand...

frequency of icing accidents relative to other weather hazards - Answer-GA has the most icing accidents and the largest percentage of fatal icing accidents 121 the most icing related fatalities Most icing accidents occur in December and January Icing is cited less than most other weather phenomena in accident reports identify trends in statistical data relating to icing accidents including the frequency of fatal icing accidents, ratings held, flight experience and phase of flight - Answer...
