Question 13 (1 point)
What is salinity?
Lesson 2.05
Question 13 options:
a liquid mixture in which the smaller component (solute) is distributed evenly through the major component (solvent)
to become incorporated with a liquid in forming a solution
the total amount of sodium dissolved in the ocean
The concentration of dissolved salt in any liquid
Question 14 (1 point)
What does evaporation do to salinity?
Lesson 2.05
Question 14 options:
evaporation does not impact salinity
water molecules (H20) absorb energy
where there are higher levels of water evaporation, the water has greater salinity
warmer water molecules move farther apart
Question 15 (1 point)
During the summer months, glaciers at the poles melt, delivering fresh water to the ocean. What does this do to salinity?
Lesson 2.05
Question 15 options:
lowers salinity
it does not change the salinity
raises salinity
Question 16 (1 point)
Look at the graph. What happens to ocean water temperatures as you go deeper under the ocean?
Lesson 2.06
Water temperatures drop dramatically as you move further down beneath the thermocline.
Question 16 options:
the temperatures drop
the temperatures increase
the temperature does not change
Question 17 (1 point)
What is density?
Lesson 2.07
Question 17 options:
the weight of water
a measure of salinity
the amount of molecules in a specific volume (space)
the amount of salt in water
Question 18 (1 point)
As the amount of salt in water increases, the of the water increases.
Lesson 2.07
Question 18 options:
temperature
size
humidity
density
Question 19 (1 point)
Deep, cold water is the .
Warm, shallow water is the .
Lesson 2.07
Question 19 options:
densest; densest
least dense; densest
densest; least dense
least dense; least dense
Question 20 (1 point)
Which layer of the ocean is the least dense?
Lesson 2.07
Question 20 options:
water in the middle layer
water closest to the ocean floor
water closest to the surface
they are all the same
Question 21 (1 point)
What is the main cause of surface ocean water circulation (movement)?
Lesson 2.09
Question 21 options:
temperature
salinity
density
winds
Question 22 (1 point)
What causes Earth’s major wind patterns?
Lesson 2.09
The Seasons | Astronomy
Question 22 options:
The density of ocean water changed wind patterns
The Earth is spinning
The latitudes of different areas
Radiant energy from the sun strikes Earth unevenly.
Question 23 (1 point)
How are ocean waves formed?
Lesson 2.13
Question 23 options:
convection
conduction
gravity
energy transfer
Question 24 (1 point)
The waves energy runs through water molecules, but they do not move the water molecules in the direction of the waves.
Lesson 2.13
Question 24 options:
True
False
Question 25 (1 point)
How do water particles in an ocean wave move?
Lesson 2.13
Question 25 options:
in a circular motion
back and forth
up and down
from one side to the other
