40 Brilliant Photographs of Undersea Life

Photographs have a way of naturally shifting our emotions. The ocean is a calming sentiment to humans since we’re so comfortable living on the land. But there is a whole ecosystem underneath the water that many of us are not even aware exists. The Earth is a beautiful place and it has been only recently that we’ve created the technology to capture these moments in time.

Undersea Life Chatter

Undersea Life Chatter

I’ve collected 40 stunning photos taken under the oceans all around the world. The lifestyle of animals can differ greatly based on how they live and behave amongst other animals. Photograph enthusiasts will love this showcase and surely gather some wonderful concepts about undersea life forms. Additionally please feel free to share your thoughts or questions below in the post discussion area. Read more

Save water…give life

STEFANOS MICHAELIDES – Greece

The ad is inspired by the relay race. The image shows two hands, the one holds the baton, which is made by water and passes it to the next hand, which symbolizes the future generation. It’s a symbolism that expresses the message. Read more

Mimicking nature: Integrate your home hydrological cycle

The Earth’s hydrological cycle has been recycling our global water supply since the birth of the planet. Water from the surface evaporates, is cleansed in the atmosphere, and then returns to the surface, which captures every last drop in order to begin the cycle anew.

 

Imagine if the world, instead of recapturing rain water, had a drain like your sink or bathtub. Valuable freshwater would be lost from the cycle and lead to the eventual depletion of the planet’s water supply. Read more

Adhesion and Cohesion of Water

I used to wake up in a cold sweat in the middle of the night because I could not get the concepts of water adhesion and cohesion clear in my mind. If you have that problem, too, then do yourself a favor and read on to learn about these important properties of water.

Cohesion: Water is attracted to water
Adhesion: Water is attracted to other substances

Adhesion and cohesion are water properties that affect every water molecule on earth and also the interaction of water molecules with molecules of other substances. Essentially, cohesion and adhesion are the “stickiness” that water molecules have for each other and for other substances. You can see this in the picture to the right. Read more

Capillary action

Even if you’ve never heard of capillary action, it is still important in your life. Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.

 

 

Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances). Adhesion of water to the walls of a vessel will cause an upward force on the liquid at the edges and result in a meniscus which turns upward. The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the walls is stronger than the cohesive forces between the liquid molecules. The height to which capillary action will take water in a uniform circular tube (picture to left) is limited by surface tension and, of course, gravity. Read more
