Question 5

Question
5- If temperature remains constant with an increase in altitude there is:
Answer
  • an inversion
  • an inversion aloft
  • uniform lapse rate
  • an isothermal layer

Question 6

Question
6- The tropopause is:
Answer

  • the layer between the tropopause and the stratosphere
  • the layer beyond which only cirrus clouds occurs
  • the line in dicating clear air turbulence

Question 7

Question 13

Question
13.- The method by which energy is transferred from one body to another by contact is called
Answer
  • radiation
  • convection
  • conduction
  • latent heat

Question 14

Question
14.- The geostrophic wind blows:
Answer
  • parallel to curved isobars
  • when pressure values are changing rapidly
  • in a tropical revolving storm
  • when geostrophic force and pressure gradient force are equal

Question 15

Question
15.- In a saturated atmosphere air which is forced to rise will:
Answer
  • tend to regain its former position if the ELR is less than the SALR
  • classified as stable air when the ELR is greater than the SALR
  • tend to regain its former position if the ELR is greater than the SALR
  • carry a rising if the ELR is less than the SALR

Question 16

Question
16.- Areas of sinking air are generally cloudless because as air sinks it
Answer
  • loses water vapour
  • is heated by compression
  • reaches warmer layers
  • is heated by expansion

Question 17

Question
17.- An adiabatic process is defined as:
Answer
  • the cooling of the atmosphere at 3oC/1000ft
  • a change of temperature brought about by a change of pressure acting on an insulated parcel of air
  • a change of temperature brought about by air being forced to rise
  • an increase of temperature in an insulated parcel of air which the pressure has been decreased

Question
19.- The process of change of state from a gas to a liquid is:
Answer

  • evaporation in which latent heat is released
  • condensation in which latent heat is absorbed
  • condensation in which latent heat is released

Question 20

Question
20.- The significance of lenticular cloud is:
