temperature

Question 1

what is climate

Answer 1

average weather condition of a specific place over more than 30 years

Question 2

what is temperature

Answer 2

conditions of the atmosphere at specific place over a relatively short period of time

Question 3

what are the elements of weather

Answer 3

1. temp
2. RH
3. clouds
4. rainfall

Question 4

latitude: temp near equator

Answer 4

-angle at which sun’s ray strike earth is higher
-result in solar radiation being concentrated over smaller area
-hence temps are higher

Question 5

latitude: temp further from equator

Answer 5

-angle at which sun’s ray strikes earth is lower
-results in solar radiation being spread out over larger area
-hence temps are lower

Question 6

altitude: base of mountain

Answer 6

-air is dense with more air and dust particles which absorb and retain more heat
-this is because gravity pulls most of the air molecules towards ground surface

Question 7

altitude: top of mountain

Answer 7

-air is less dense with less air and dust particles which absorb and retain less heat

Question 8

lapse rate

Answer 8

6.5 degree celsius drop for every 1000m increase in altitude

Question 9

cloudy day: daytime

Answer 9

-clouds reflect some solar radiation back into space
-results in less solar radiation reaching ground
-hence relatively lower temp

Question 10

cloudy day: nighttime

Answer 10

-clouds slow down rate at which heat escapes into space
-hence cloudy nights feel warmer as atmosphere retains more heat

Question 11

cloudless day: daytime

Answer 11

-incoming solar energy can reach earth’s surface without obstruction
-hence ground heats up more quickly, resulting in warmer temp

Question 12

cloudless day: nighttime

Answer 12

-clear skies allow maximum amount of heat to escape into space
-hence atmosphere cools down quickly, resulting in relatively lower temp
