Sections 12.1 and 12.2 of the text discuss the origin and composition of the world ocean’s seawater.

What is the current theory on the evolution of the world ocean?
Scientists do not yet agree as to where the Earth's water came from. According to the text, some water were in the materials that formed Earth. That water was released as steam from volcanoes. The text also states that more

There the absent of continental boundaries allow the strong west winds around Antarctica to bring forth a continuously flowing current called Antarctic circumpolar current. The North Atlantic drift is in the northeastern Atlantic Ocean. This west wind drift forms a considerable warm current. This current spreads around the Bristish Isles, into the North Sea, and along the Norwegian coast. In time, the current cools and sinks, flowing equatorward along the ocean bottom. The Coriolis effect delfects the actual direction of water drift about 45 degrees from the direction of the driving wind.

Figure 13.3 in the textbook helps visualize how tides are developed. In 150 words, answer the following:

What role does the Moon, Sun, and inertia play in the development of tides?
Tides are a change in sea levels that happens on a regular daily basis. Tides happen because of the gravitational attraction between the Moon, the Sun and Earth. The gravitational attraction of the Moon will pull the ocean water to the Earth's nearest Moon, this makes it bulge outward. There is also an inertail force, this is when the ocean will bulge away from the Moon on the opposite side of the Earth. The Sun is much farther from Earth than the Moon, so its tide producing force is only half as strong.
Why is there a variation in tidal ranges?
Tidal ranges are the differences between high and low tide. The tidal ranges can vary depending on the location
