quiz unit 3

Question 1

what properties make water so unique

Answer 1

states of water
makes up most our bodies and about 80 percent of marine orgnisms
hydrogen bonds
universal solvent

Question 2

states of water

Answer 2

solid liquid gas

Question 3

liquid

Answer 3

H bonds
moving molecules
temp increases as molecular movment increases

Question 4

Gas

Answer 4

no H bonds molecues spread out FAST

Question 5

solid

Answer 5

so cold molecules lock into crystal pattern, moleculares farther apart then liquid

Question 6

Rank

Question 7

Rank states of water from most to least dense

Answer 7

LSG

Question 8

Because of ____ it kaes a lot more _____________ to ____

Answer 8

hydrogen bonds
heat and energy, to change temp of water
takes a lot more heat and energy removal to freeze

Question 9

the amount of energy needed to raise temp of water 1 degree celsius

Answer 9

for water specific heat very high

Question 10

water is a universal solvent

Answer 10

can dissove more things than any other natural substance
very good at dissolving salts and ions
NaCl+ and Cl-
charge from water molecules pulls the Na and Cl apart

Question 11

materials in sea come from:

Answer 11

weathering
breakdown of continental crust
carried into sea by rivver
earths interior
also releases into atmosphere by volcanoes then falls in precipitaiton

Question 12

density

Answer 12

mass of a gievn volue of a sybstane

mass/volume

Question 13

salinity of seawater

Answer 13

composed of about 6 diff ions
sodium chlorida 85 percent
salinity varies by body of water
higher salinity=higher density (sink)

Question 14

where is salinity highest

Answer 14

atlantic because its hotter so evaporates which leaves more salt behind

Question 15

where is salinity lowest

Answer 15

coastlines because freshwater run off from rivers

Question 16

deeper it is…

Answer 16

the lower the surface salinity

Question 17

seawater is relativley transparent so sunlight can ____ this is vital bc

Answer 17

penetrate through the ocean

all photosynthesis organisms need water to grow

Question 18

different ____ penetrate different depths dependign on the frequency

Answer 18

colors

Question 19

marine organisms withstand _____

Answer 19

pressure of the atmosphere as welll as ocean on top of them (many organisms have special adaptions to withstand

Question 20

gasses dissolve better in

Answer 20

cold water

Question 21

ocean hold stores more than ______ as much as the total CO2 in the atmospherw

Answer 21

50

Question 22

ocean circulation

Answer 22

driven by win and is infulenced bu the coriolis affect

Question 23

cariolis effect

Answer 23

bc the earth is round and rotates anything that moves over its surface tends to turn a little this affects wind patterns and surface currents

Question 24

what drives ocean currents

Answer 24

wind drives surace currents by pushing water

Question 25

temp and salinity cause change in

Answer 25

density

Question 26

surface currents result from flobal wind patterns which are cuased by

Answer 26

uneven heating of earths suface

Question 27

what occurs in major ocean basins

Answer 27

ocean gyres

Question 28

warm equitorial waters are driven

Answer 28

westward by tradwwinfs

Question 29

ocean gyres play a major role in maintaining

Answer 29

earth's heat balence

Question 30

the gulf streams

Answer 30

play role in.. earths climate transporting large amount of heat energy

Question 31

warm surface currents

Answer 31

increase rate of evap heavy rainfall near coasts high cloud cover high humidity

Question 32

cold surface currents

Answer 32

low evap arid dry coastlines (CALI) less clouds foggy

Question 33

upwellings

Answer 33

deliver cold, nutrient-rich water to surface occur where wind force water away from coastline or where seamount can deflect water up water becomes fertilized increasing productivity of plankton and producing strong foodwbs

Question 34

draw diagram of upwelling on coasline and on seamount

Answer 34

right coastline and upwlling arrows up coastline a d strong plankton on top right next to it and going to left and sea moutain and upwelling arrow go up left and then strong plankton on topgo to right

Question 35

downwelling

Answer 35

sinking of surface water more dense watwer sinks

Question 36

global ocean converyer belt

Answer 36

system of slow moving currentts that begin witht he downwelling of the north atlantic deep water current and travels through all the oceans include surface, deep, and vertical currents

Question 37

el nino

Answer 37

every 3-7 yrs chsnge in wind patterns refult in shift in ocean temp and currents rain patterns disrupts gfood wbs

Question 38

normal conditons in pacific

Answer 38

strong tradwinds blow W across equitorial pacific upwlling strong along coast of S America

Question 39

el nino conditions in pacific ocean

Answer 39

tradwinds weaker eastern pacific becomes warmer bc arent pushes west anymore more evap in E pacific food webs collapses

Question 40

la nina

Answer 40

opposite of el nino tradwinds stronger warm water pushed W

Question 41

cal currents

Answer 41

left of calli

Question 42

humboldt current

Answer 42

left of S america

Question 43

gult stream

Answer 43

right of americ and beneath
