Unit 4 TEST

Front

What is the densest state of seawater?

Back

Seawater is densest when salinity is high and its temperature is low.

Front

What causes ocean waves?

Back

Ocean waves are most likely caused by surface winds.

Front

How does sunlight affect evaporation?

Back

Sunlight increases evaporation; water in a sunny location will evaporate faster than in a dark location.

Front

What does the continental shelf symbolize?

Back

The continental shelf is represented by the number 1 on oceanic diagrams.

Front

What creates ocean tides?

Back

Ocean tides are created by the gravitational pull of the Sun and Moon on Earth's water.

Front

Define salinity.

Back

Salinity is the concentration of salts in water, usually measured in parts per thousand.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, typically due to heat.

Front

Explain the role of the Moon in ocean tides.

Back

The Moon's gravitational pull affects the water on Earth, contributing to the rise and fall of ocean tides.

Front

What is the relationship between temperature and water density?

Back

As temperature decreases, water density increases; colder water is denser than warmer water.

Front

What is the effect of wind on ocean surface?

Back

Wind creates friction on the ocean surface, generating waves and currents.
