Ocean Chemistry and Coral Consumption

The video explains how bumphead parrotfish contribute to the formation of white sand beaches in the South Pacific by consuming coral and excreting it as sand. It also touches on the mystery of ocean salinity, highlighting that the understanding of its chemistry is a relatively recent development.

What is the primary contributor to the white sand on South Pacific beaches?

• Volcanic ash

• Bumphead parrotfish excrement

• Crushed seashells

• Eroded rock

How much coral can a single bumphead parrotfish consume in a year?

• 1 ton

• 3 tons

• 5 tons

• 10 tons

What happens to the coral after it is consumed by bumphead parrotfish?

• It remains unchanged

• It is turned into sand

• It is digested and absorbed

• It is excreted as liquid

Until recently, what was the common response to why the ocean is salty?

• A myth about sea creatures

• An avoidance of the question

• A detailed scientific explanation

• A simple answer about salt deposits

What aspect of the ocean's chemistry was not well understood until recently?

• Its temperature

• Its salinity

• Its depth

• Its biodiversity
