The famous pink-colored sand of bermuda's beaches is due to crushed shells of marine organisms with tests (porous shells) made of organic material hardened by calcium carbonate.

Beaches of Bermuda are lined with coral reefs, which are a place where red foraminifera are found. The foraminifera are the single-celled marine organisms classified as protists., They live in shells made of calcium carbonate with a red colour. Shells of foraminifera collect on the ocean floor and get washed to shore by the tide and that’s what makes beach looks pink on the sun. 

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

the electromagnetic energy from the sun arrives in the form of visible and invisible light.
