Imagine yourself giving a naturalist tour across the broad expanse of the ocean floor. First, using a map, select a departure point and a destination, which should be coastlines. Be careful when choosing -- you'll need to include all the major ocean provinces and seafloor features. As you move though a province or pass a major feature, explain its characteristics and origin. If the feature is tectonic in nature, explain the tectonic processes at work that created it.
