APES Chapter 6 Atmospheric Composition Flashcards
Which of the following is the highest layer of atmosphere? A) stratosphere B) thermosphere C) ozone D) troposphere E) mesosphere
B
The thermosphere has a temperature up to 1,982 degree Celsius and is affected by sun spot and solar flare activity
Which two gases make up the majority of the earth's gases? A) oxygen and methane B) oxygen and propane C) nitrogen & carbon dioxide D) benzene & nitrogen E) nitrogen & oxygen
E
Large temperature differences and strong pressure differences between warm & cold air cause the formation of the A) precipitation B) auroras C) jet stream D) clouds E) fossilization
C
When warm and cold air clash, there is often violent weather
The relationship between air temperature and the amount of wat vapor it contains is known as A) relative humidity B) indistinct humidity C) point source humidity D) aridity E) wind shear
A
The link between air temperature and water vapor (eg hotter air holds more water)
A sudden change in the winds direction or speed with increasing altitude is called A) wind stop B) wind chill C) troposphere D) wind shear E) ionosphere
D
Vertical wind shear affects a hurricanes development causing it to build
A long, narrow, upper atmosphere current of fast moving air is known as a A) Jet stream B) thermopile C) contrail D) gust of wind E) typhoon
A
Jet streams are 10 to 14 km above earth’s surface in the troposphere
A tropical depression is the first phase in the formation of a A) tornado B) cloud C) hurricane D) jet stream E) temperature inversion
C
High humidity in the troposphere and low barometric pressure also add to hurricane decelopment
In which layer do all the pressure, wind and precipitation changes occur? A) outer space B) stratosphere C) troposphere D) ionosphere E) mesosphere
C
Rising and falling temperatures, rotating air masses, and pressure keep things lively
Tornadoes of the F4/F5 category account for what percent of deaths? A) 80% B) 65% C) 40% D) 25% E) 10%
B
Most commercial aircraft travel takes place in the lower part of the
A) upper troposphere
B) United States
C) inverted air mass above a mountain range
D) stratosphere
E) ionosphere
D
Military aircraft reach much higher altitude with some grazing the mesosphere
The northern and southern lights are found in A) mesosphere B) troposphere C) stratosphere D) troposphere E) thermosphere
E
These are the Aurora Borealis (northern) and Aurora Australis (southern) lights
When moving thru the eye wall of a hurricane and into the eye, surface pressure A) increases B) decreases C) stays the same D) is at its highest E) is not rarely low
B
Pressure is lowest at the center and is used to track a hurricane’s movement
The thermosphere is also called the A) mesosphere B) troposphere C) ionosphere D) lower latitude layer E) El Niño effect
C
From the many ions present from cosmic radiation
ENSO takes place at intervals of 2 to 7 years and lasts approximately A) 6 months B) 1 to 2 years C) 3 years D) 2 to 5 years E) 7 years
B
A hurricane's course depends upon location and A) trade wind direction B) eye size C) speed D) name E) eye wall
A
Temperature and pressure are also important factors
