29. Reviewing Main Ideas 1
Ocean Water
Earth’s ocean water might have originated from water vapor released from volcanoes. Over millions of years, the water condensed and rain fell, filling basins.
The oceans are a mixture of water, dissolved salts, and dissolved gases.
Ions are added to ocean water by rivers, volcanic eruptions, and the atmosphere. When seawater is evaporated, these ions combine to form salts.

30. Reviewing Main Ideas 2
Ocean Currents
Wind causes surface currents. Surface currents are affected by the Coriolis effect.
Cool currents off western coasts originate far from the equator. Warmer currents along eastern coasts begin near the equator.
Differences in temperature and salinity between water masses in the oceans set up circulation patterns called density currents.

31. Reviewing Main Ideas 3
Ocean Waves and Tides
A wave is a rhythmic movement that carries energy.
In a wave, energy moves forward while water molecules move around in small circles.
Wind causes water to pile up and form waves. Tides are caused by gravitational forces.

Question 3
The rise and fall in sea level is a __________, caused by a giant wave produced by the gravitational pull of the Sun and Moon.
A. current
B. crest
C. range
D. tide
PS 1.1e

36. Chapter Review
Answer
The answer is D. Although the wave causing the tide has a height of only 1-2 m, its wavelength is thousands of kilometers long.

37. Chapter Review
Question 4
What is the difference between the ocean levels at high and low tides called?
Answer
This difference is called the tidal range. Most shorelines have tidal ranges of 1-2 meters, but there are places with tidal ranges greater than 10 m.
