SSA Bronze Badge Study Guide Q241-260

241) Where might you find rotor cloud?
a) Over hilltops and in the lee of hills in association with wave systems.
b) Along a sea breeze front in association with strong lift and sink.
c) In front of orographic cloud.

242) What happens to visibility and temperature at the passage of a cold front?
a) Visibility increases and temperature decreases.
b) Visibility decreases and temperature decreases.
c) Visibility increases and temperature increases.

243) What is the approximate rate of change of temperature with height for the dry adiabatic lapse rate?
a) 3 degrees Celsius loss per 1000 feet height gain.
b) 2 degrees Celsius loss per 1000 feet height gain.
c) 1 degree Celsius loss per 1000 feet height gain.

244) What are the three main stages called in the life cycle of a thunderstorm?
a) The cumulus stage, the mature stage and the dissipating stage.
b) The cumulus stage, the mature stage and the precipitation stage.
c) The cumulus stage, the precipitation stage and the dissipating stage.

245) What is the cause of a sea breeze front?
a) Sea heating more quickly than the land, which causes the air to rise over the sea. This in turn leads to advection and the sea breeze.
b) Cooler sea air mixing with an offshore breeze creates the frontal system.
c) Land heating more quickly than the sea, which causes the air to rise overland, which in turn leads to advection and the sea breeze.

246) What is the cause of katabatic winds?
a) Cooling air becomes more dense and therefore sinks. At night this sinking air will flow down hills and through valleys creating the wind.
b) Warm air becomes less dense and rises. With the sun on a slope during the day, warm air flows up hill creating the wind.
c) The wind blowing over a ridge creates a low pressure on the leeward slope, which in turn sucks air out of the leeward valley creating the wind.

247) What is the name given to the point at which water vapor condenses, and what is the required humidity?
a) The dew point and can occur at any percentage saturation.
b) The saturation level and can occur above 90% saturation.
c) The dew point and requires 100% saturation.

248) Which of the following is the most accurate definition of the adiabatic lapse rate?
a) The rate of change of temperature due to expansion with increasing height, taking into account the moisture content, i.e. dry or saturated.
b) The rate of change of temperature with increasing height.
c) The rate of change of pressure with height, taking into account the moisture content, i.e. dry or saturated.

249) Which direction does air flow around a high pressure in the northern hemisphere?
a) Anticlockwise.
b) Clockwise.
c) From low pressure to high pressure.

250) What is the name given to lines depicting points of equal pressure on a synoptic chart?
a) Isogonals.
b) Isobars.
c) Contours.

251) What is the cause of anabatic winds?
a) Cooling air becomes more dense and therefore sinks. At night this sinking air will flow down hills and through valleys creating the wind.
b) Warm air becomes less dense and rises. With the sun on a slope during the day, warm air flows up hill creating the wind.
c) The wind blowing over a ridge creates a low pressure on the leeward slope, which in turn sucks air out of the leeward valley creating the wind.

252) What is the cause of wind?
a) The Coriolis force.
b) Pressure differences trying to reach equilibrium.
c) The rotation of the earth.

253) In the Northern Hemisphere, if a glider is accelerated or decelerated, the magnetic compass will normally indicate:
a) A turn toward north while decelerating on an east heading.
b) Correctly only when on a north or south heading.
c) A turn toward south while accelerating on a west heading.

254) In the Northern Hemisphere, a magnetic compass will normally indicate initially a turn toward the west if:
a) A left turn is entered from a north heading.
b) A right turn is entered from a north heading.
c) An aircraft is accelerated while on a north heading.

255) What is an important airspeed limitation that is not color coded on airspeed indicators?
a) Never-exceed speed.
b) Maximum structural cruising speed.
c) Maneuvering speed.

256) During flight, when are the indications of a magnetic compass accurate?
a) Only in straight-and-level unaccelerated flight.
b) As long as the airspeed is constant.
c) During turns if the bank does not exceed 18 deg.

257) If the pitot tube and outside static vents become clogged, which instruments would be affected?
a) The altimeter, airspeed indicator, and turn-and-slip indicator.
b) The altimeter, and airspeed indicator.
c) The altimeter, attitude indicator, and turn-and-slip indicator.

258) In the Northern Hemisphere, the magnetic compass will normally indicate a turn toward the south when
a) A left turn is entered from an east heading.
b) A right turn is entered from a west heading.
c) The aircraft is decelerated while on a west heading.

259) The pitot system provides impact pressure for which instrument?
a) Altimeter.
b) Vertical-speed indicator.
c) Airspeed indicator.

260) What does the red line on an airspeed indicator represent?
a) Maneuvering speed.
b) Turbulent or rough-air speed.
c) Never-exceed speed.
