101-1 The Atmosphere

Question 1

Troposphere

Answer 1

1st layer above earth’s surface
Characterized by temperature lapse rate
All weather begins here
Thickest at equatorial regions due to solar radiation

Question 2

Tropopause (TROP)

Answer 2

Jet stream is found here
Max wind speeds occur in or near TROP
Turbulence
Abrupt change in temperature lapse rate

Question 3

Stratosphere

Answer 3

Primarily isothermal (no change) above polar TROP with warming trend above tropical TROP
Winds decrease as altitude increases

Question 4

Weather

Answer 4

State of the atmosphere

Question 5

Meteorology

Answer 5

Science (study) of the atmosphere

Question 6

Composition of Air

Answer 6

78% Nitrogen, 21% Oxygen, 1% Other
The more H20 added to the air, the air density will decrease (h20 is lighter than N2 and 02)
