when atoms transfer valence electrons.
hydrogen bonds to chlorine
two positive ions approach each other
Density =
volume divided by mass

Why can ice float when put in water?
Gravity
The atmospheric pressure allows it to float
It has less water in it then the water does
Its less dense than the water
Increased Pressure =

elements
One of the reasons that so many minerals become dissolved in the water at hydrothermal vents is because
minerals dissolve better the hotter the water is
minerals dissolve better in dark water
Minerals require high salinity conditions to dissolve
The deeper zones of the ocean are cold and have a high salinity, which means that gases, such as oxygen,
commonly break apart into single atoms
will be found in higher concentrations
will be found in lower concentrations
Estuary areas see big changes in salinity due to
surface runoff
evaporation
precipitation
all of these reasons are correct
Which of the following would most accurately measure pH in ocean water?
blue litmus
universal indicator paper
digital pH probe
none of these can accurately measure pH
As the salinity of water increases, the freezing point of the water
increases
decreases
stays the same, freezing point is not influenced by salinity
Which of the following is a reason that floating ice is important for marine organisms?
the underside of icebergs and ice sheets acts as a habitat for phytoplankton and algae
the marine ice provides habitat for marine organisms such as polar bears that hunt from the ice
the ice acts as a thermal insulator, keeping layers of water below it from freezing
All three of these reasons are correct
