Water is a unique molecule. Most liquids become denser as they cool down, but when water freezes, it becomes less dense, allowing ice to float. If ice did not float, a lot of animals would be in trouble. In fresh water ecosystems, animals rely on the top layer of water freezing over, which actually allows heat to be trapped underneath and keeps them alive through the winter.
Ocean phytoplankton produce at least half of the oxygen that we breathe. Though small in size they are able to produce as much oxygen as all of the land plants on earth combined. While trees and plants usually get all the credit for our oxygen, we actually should be thanking our marine plankton!
A tsunami is a giant wave generated when an earthquake, landslide, or volcanic eruption occurs under water. The wave can carry a large amount of energy. As this massive energy approaches shore, the wave grows higher and higher and can come very far inland. Always heed tsunami warnings and head to higher ground!
You may have known that corals are living animals but did you know that they have a partnership with algae living inside of them? Algae known as zooxanthellae (zo-zan- thel-ay) live in the coral’s tissue. The coral gives the algae protection and nutrients while the algae provide food and oxygen to the coral in return. When two living organisms help each other out like this we call it a symbiotic relationship.
Scientists in Canada got a surprise while doing studies on human forensics. To look at how bodies decompose, they tossed pig carcasses into so called "dead zones", areas of low oxygen in the ocean. However, much to their surprise, sharks, lobsters, and other scavengers risked going into these suffocating conditions and ate their experiment!
Photo: NCAR Science Daily March 6, 2017 New research findings show that as the world warmed millions of years ago, conditions in the tropics may have made it so hot some organisms couldn't survive. Longstanding theories dating to the 1980s suggest that as the rest of Earth warms, the tropical temperatures would be strictly limited, or regulated by an internal 'thermostat.' These theories are controversial, but the debate is of great importance because the tropics and subtropics comprise half of Earth's surface area, greater than half of Earth's biodiversity, as well as over half...
