Select each statement that correctly summarizes and compares properties of the ocean.

The amount of salt dissolved in ocean water never changes.

The ocean is mostly salt water, but parts are fresh water.

The deep ocean is generally less salty than surface water.

Warm ocean water has higher salinity than cool ocean water.

Ocean water is warmer farther from the equator.

Clouds form as rising water vapor warms and condenses.

Solar radiation warms ocean water and increases evaporation.

Sinking warm water produces ocean currents that affect weather.

Ice can float since it has a lower ____ than water.
Controlling factor is the total volume of water compared to the amount of dissolved solids in water
At lower temperatures, water molecules are moving slower and are packed more tightly together.
Warmer water is able to dissolve solids faster than cold water.
The ______ of ocean water usually decreases as depth increases.

Match the corresponding parameters that can be measured to describe waves with the correct definition.

Stavka koja se može prevući		Odgovarajuća stavka
crest		amount of time between two wave crests (from a fixed reference point)
wavelength		measurement of the vertical distance between the wave's crest and trough
wave speed		horizontal distance between two wave crests, or two wave troughs
trough		dividing the wavelength by the wave period
wave period		lowermost point of a wave
wave height		uppermost point of a wave

An observer sitting in an anchored boat in a bay is watching waves go by. She notices that there is a distance of 10 meters between wave crests, and that a new wave crest passes her boat every 5 seconds. What is the wave speed?

The wave speed is 2 λ.

The wave speed is 2 T.

The wave speed is 2 m/s.

The wave speed is 2 v.

An observer sitting on the shore sees four waves with equal wavelengths travel by. The distance between the first and fourth wave crests is 30 meters. It takes 21 seconds for all four wave crests to pass. What is the wave speed?

The wave speed is approximately 5.3 m/s.

The wave speed is approximately 7.5 s/m.

The wave speed is approximately 0.35 s/m.

The wave speed is approximately 1.4 m/s.

As a fishing boat travels through the ocean, crew members watch as they pass two wave crests. The distance between the crests is 15 meters. The time it takes to travel from the first crest to the second is 7.5 seconds. What is the wave speed?

The wave speed cannot be accurately calculated because the observers are not stationary.

The wave speed is 2 m/s.

The wave speed is 2.

The wave speed cannot be accurately calculated because the v is unknown.

As a wave approaches the edge of the land, drag against the ocean floor causes the side closer to land to slow down while the rest of the wave continues forward. This causes a bend in the wave's overall path and this phenomenon is known as
