1

Characteristics of salinity

Made of electrically charged Na+and Cl ions
Salinity lowers freezing point and increases density.

2

What is thermocline?

Temperature change

3

What is pycnocline?

Change in density

4

What is diffusion?

Low to high concentration

5

What is osmosis?

High to low concentration

6

H20 characteristics

Polar molecule
Universal solvent
High heat capacity
Thermally stable

7

What is one atmosphere of pressure?

33 ft, 14.7 lbs per sq. inch

8

What is the oxygen minimum layer?

The area in which 02 gets used up; underneath marine snow causes it to increase again,

9

Characteristics of active margins

Tectonic activity, subduction

10

Characteristics of passive margins

Despositional, on coastlines

11

Characteristics of sound in water

4 times faster, up to 60 times louder, travels farther

12

What is Osmoregulation?

Change with internal salinity

13

What is an osmoconformer?

Change with outside salinity

14

What is isosmotic?

Same salinity inside and outside

15

What is hyperosmotic?

Saltier inside

16

What is hypoosmotic?

Saltier outside
