1. What is the warmest ocean and the warmest sea?

Answer: Indian, Red

This sea is part of the Great Rift Valley.
2. Scientists have found balls on the abyssal seafloor. What are they made of?

Answer: manganese

These balls are formed around organic material that has drifted to the seafloor, usually around a shark tooth, which are plentiful as sharks have a lifetime supply of teeth that rotate in as a tooth is lost. There is no way, currently, to harvest these balls for commercial use.
3. Some oceans are continually growing. This is due to?

Answer: seafloor spreading

Since the beginning of the planet, the ocean geography has changed radically.
4. Corals are classified as which of these?

Currently, coral bleaching is a serious threat to coral reefs around the world. Bleaching can be caused from noxious land runoff (pesticides, oil and gas), and also from temperature changes, such as El Nino.

Answer: dinoflagellates

One should not eat shellfish that have been affected by a red tide.

This evolutionary survivor still displays lobed fins.

Answer: deep ocean earthquakes

The majority of tsunamis occur in the Pacific Ocean.
9. What is the topography of the ocean floor called?

Answer: bathymetry

Early peoples charted the seafloor using weighted lines, called line sounding.
