follow in a horizontal line to the axis and record angle (figure 8 diagram)

Question 8

finding angle of the noon sun (formula)

Answer 8

ANS = 90 deg - (Latitude +/- latitude of sub solar point0

will be + if in southern hemisphere, - if in northern

Question 9

equinoxes

Answer 9

top and bottom of the figure 8 diagram

Question 10

lapse rate

Answer 10

change in temp / change in altitude

eg. point 1: (30C, 200m)
point 2: (15C, 100m)

lapse rate:

30-15C / 200-100m = 15C/100m

Question 11

relative humidity (3 formulas)

Answer 11

actual water vapour in air/ max capacity of vapour pressure in air x 100

vapour pressure / saturation vapour pressure x 100

SVP dew/SVP dry x 100

Question 12

wet bulb depression

Answer 12

dry bulb temp - wet bulb temp

Question 13

dew point (on weird lines diagram) (3)

Answer 13

find wet bulb depression

follow up to meet dry bulb temp intersection on graph

the follow diagonal line down to get the dew point ( it will be a point on the “dry bulb” axis

Question 14

SVP

Answer 14

saturation vapour pressure

Question 15

SVP dry (3)

Answer 15

find dry bulb temp

then go directly left to SVP axis

that number will be SVP dry

Question 16

SVP dew

Answer 16

find dew point (wet bulb depression, follow up to dry bulb temp, slide down to axis)

once you have that, go directly left to get SVP due (will be on SVP axis)

Question 17

DAR

Answer 17

10C/1000m

Question 18

MAR

Answer 18

6C/1000m

Question 19

intensity of sun angle

Answer 19

intensity = sin(ANS)

Question 20

BEC (acronym)

Answer 20

Biogeoclimatic ecosystem classification

Question 21

Biogeoclimatic ecosystem classification facts

Answer 21

divides places by climate and vegetation

zones change with climates

Question 22

short-wave radiation

Answer 22

visible

emitted by the sun

Question 23

longwave radiation

Answer 23

not visible

infrared

emitted by earth

carbon dioxide absorbs this

Question 24

divergent boundary (on map)

Answer 24

drawn by a Line with dashes (like stitches)

Question 25

subduction zone

Answer 25

drawn as a line with arrows/triangles in the direction of subduction

Question 26

transform

Answer 26

drawn as line with opposite pointing arrows

Question 27

velocity

Answer 27

distance / time

Question 28

lava/magma classification

Answer 28

mafic
- low silica
- fast
- low viscosity

felsic
- high silica
- slow as fuck

Answer 46

small disturbances + lots of time
chain effect, one curve creates more curves as it directs water to hit the sides of the stream on the way out of the curve
