#1
Front (Question)

What scatters light in the atmosphere so we can see the atmosphere?

Back (Answer)

Dust clouds ad aerosols

#2
Front (Question)

Layers of the atmosphere (4)

Back (Answer)

1) Troposphere 2) Stratosphere 3) Mesosphere 4) Thermosphere

#3
Front (Question)

Temperature profile of the atmosphere in the: 1) Troposphere 2) Stratosphere 3) Mesosphere 4) Thermosphere

Back (Answer)

1) Decreases as height increases 2) Increases due to ozone absorbing UV 3) Decreases as height increases 4) Increases due to charged particles hitting into each other

#4
Front (Question)

(No need to learn but it is nice to know) Layer above the thermosphere

Back (Answer)

Exosphere

#5
Front (Question)

(No need to learn but it is nice to know) Layer that combines Thermosphere & Exosphere

Back (Answer)

Ionosphere

#6
Front (Question)

(No need to learn but it is nice to know) Layer between troposphere and ionosphere

Back (Answer)

Ozonosphere

#7
Front (Question)

Troposphere 1) Define 2) Where it lies 3) Constituents 4) What occurs in this layer 5) Where is the highest troposphere layer & (6) why

Back (Answer)

1) Layer closest to the surface 2) Around 10 km 3) Water vapor (99%) & clouds 4) Most turbulent mixing (all weather happens) 5) At the equator 6) This is where the most turbulent mixing occurs, heating from below

#8
Front (Question)

What are layers defined by

Back (Answer)

Change in the lapse rate +ve to -ve or vice versa

#9
Front (Question)

Lapse Rate 1) Define 2) SI units

Back (Answer)

1) Rate of change of temperature with height 2) Degrees C km -1

#10
Front (Question)

Positive Lapse rate

Back (Answer)

Decrease in temperature with height

#11
Front (Question)

Negative lapse rate

Back (Answer)

Increase in temperature with height

#12
Front (Question)

Stratosphere 1) Define 2) Where it lies 3) Constituents 4) What occurs in this layer (3) 5) Temperature up to 25 km 6) After 25 km

Back (Answer)

1) 2nd layer of atmosphere 2) 10-50 km 3) Ozone 4) Very little: mixing, water vapor & turbulence 5) Relatively constant 6) Gradually increases to 200 - 220 k

#13
Front (Question)

Mesophere 1) Define 2) Where it lies 3) Constituents 4) What happens to temperature 5) Temperature at mesopause

Back (Answer)

1) 3rd layer of atmosphere 2) 50 - 80 km 3) neon, argon, hydrogen 4) Decreases with height 5) 190 - 180 k

#14
Front (Question)

Auroras 1) How do we get them and what does earth’s magnetic fields have to do with it? 2) Where do they lie?

Back (Answer)

1) Charged particles get pulled towards the poles, at incredible speeds & they hit other particles 2) Ionosphere (Thermosphere & Exosphere)

#15
Front (Question)

Solar flares 1) What happens to them? 2) How often do they occur?

Back (Answer)

1) The highly charge particles from the sun get trapped at the pole 2) 10 to 11 years

#16
Front (Question)

Boundary layer

Back (Answer)

Height in the atmosphere where the air is effected by what happens at the surface

#17
Front (Question)

Temperature gradient of the poles to equator in the atmosphere at the 1) surface 2) Stratosphere & above

Back (Answer)

1) Lower at poles (tropopause), Higher at equator 2) Higher at poles, Lower at equator
