Want this question answered?
Some insects are able to move around on a lake or pond because of the surface tension of the lake or pond.
Surface of water
Ripples on the surface of a pond are an example of wave motion.
standing surface water
it is when water molecules in the water form a 'wall'.Pond skaters have legs that spread out away from their bodies, lowering the pressure exerted by their weight and not breaking the surface tension of the water
Ripples i believe you are looking for
A water strider can walk across the surface of a small pond.
Pond skaters use surface tension to "walk" on water. They're legs are covered in fine hairs that are super sensitive and repel water. The hairs sense vibrations and ripples on the water's surface. The pond skater then uses these ripples to walk across the water surface. Check out the Jesus Christ lizard, its equally amazing! Saw it on Animal planet this morning. Hope this helps! :)
Euglena live at the surface of the water/pond!
The sun heats the water surface. Warm water has a lighter density than cold water so the warmer water floats on the surface of the colder water.
Pond skimmers
Fishes swam merrily under the surface of the pond.
