22
What is a measure of the amount of dissolved salts in a given amount of liquid?
Desalination
Density
Salinity
Thermohaline circulation
23
Why are average temperatures lower at the poles than at the equator?
The poles receive no sunlight
The sun's strikes at an angle less than 90 degrees
The sun strikes the ground at a 90 degree angle
The winds keep the poles at a lower temperature
24

Saltwater
Sharks
Seaweed
25
Why do oceans have a major effect on climate?
Source of moisture and heat
Water heats the land
there is a large amount of salt
help create clouds
26

average precipitation
seasons
climate
weather
27
As ocean water becomes warmer it becomes......
hotter
less dense
saltier
denser
