Quiz Answer Key and Fun Facts

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?

Answer: animals

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.

5. Which of these causes red tides?

Answer: dinoflagellates

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

6. What are the (usually) microscopic ocean animals called?

Answer: zooplankton

Some of these animals stay microscopic, while others grow into larger animals.

7. What animal was thought extinct until one was caught in 1938?

Answer: coelacanth

This evolutionary survivor still displays lobed fins.

8. What are tsunamis generally spawned from?

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.

10. Sea snakes are the least venomous snakes in the world.

Answer: False

Sea snakes have one of the world's most toxic venoms. A complete envenomation can kill three adults. Fortunately, sea snakes are notoriously shy, and avoid humans.
