| Recognition of Topographic Features
on the Seafloor |
| Examine detailed maps of seafloor topography
for the appropriate areas of the ocean, naming the specific features that
occur at designated locations. |

| Locations of Topographic Features on
the Seafloor |
Again examine the detailed maps of seafloor
topography for the three designated maps of the ocean, recognizing locations
of the specific topographic features.
Locate the following types of topographic feature on the map of
Australia and the surrounding areas of the Indian, Southern and Pacific Oceans
and give their co-ordinates (latitude and longitude). You need designate
only one location on each chosen feature.
