Ch 4 Mats

Question 1

whats deposition

Answer 1

ice forms directly from water vapor

Question 2

what happens to boiling point when pressure is decreased?

Answer 2

lower boiling point

Question 3

what powers the growth of cumulonimbus storm clouds

Answer 3

latent heat released by condensing water vapor

Question 4

whats the mixing ratio formula

Answer 4

mass of water vapor in grams / mass of dry air in kilograms

Question 5

absolute humidity forumla

Answer 5

mass of water vapor in grams / volume of air in cubic meters

Question 6

whats saturation

Answer 6

balance b/w evaporation and condensation

Question 7

where does adiabatic cooling and warming come from

Answer 7

expansion or compression

Question 8

what are the 4 causes of the lifting of air parcels

Answer 8

orographic lifting
frontal wedging
convergence
convective lifting

Question 9

orographic lift

Answer 9

the windward side of a mountain is much wetter than the leeward side

Question 10

frontal wedging

Answer 10

the horizontal flow of warm air pushes the warm air above the cold

Question 11

convergence

Answer 11

converging winds meet to rise the air parcel

Question 12

absolute stability

Answer 12

occurs b/c the parcel is cooler than the local environment everywhere, and thus tends to SINK!

Question 13

absolute instability

Answer 13

air parcel warmer than the environment tends to rise and keep rising

Question 14

what happens w/ absolute instability

Answer 14

dramatic and rapid cloud growth

Question 15

conditional instability

Answer 15

dry rate and wet rate on either side of the level of free convection

Question 16

in mountain diagram, what happens when you reach the condensation level (dew point)

Answer 16

its no longer the dry lapse rate, but the wet lapse rate (until the to p of the mountain)

Question 17

what is the hydrologic cycle

Answer 17

the movement b/w the oceans, the atmosphere, and the continents

Question 18

what happens to hydrogen bonds when water changes states?

Answer 18

the hydrogen bonds are either broken or formed

Question 19

evaporation

Answer 19

the process of converting a liquid into a gas (vapor)

Question 20

condensation

Answer 20

water vapor changes to the liquid state

Question 21

assumed dry lapse rate

Answer 21

10

Question 22

assumed wet lapse rate

Answer 22

5
