A basking honu is perfectly happy to be the subject of photographs. To ensure that the turtles are not bothered, volunteers at Laniakea use red rope to mark off a no-go zone, and place signs to keep visitors informed. The turtle in the foreground doesn't get a red rope because even though it's a pretty good sand sculpture, it didn't fool the volunteers.
Why evaporation occurs. Heat (energy) is necessary for evaporation to occur. Energy is used to break the bonds that hold water molecules together, which is why water easily evaporates at the boiling point (212Â° F, 100Â° C) but evaporates much more slowly at the freezing point.
1 As water is boiled, kinetic energy causes the hydrogen bonds to break completely and allows water molecules to escape into the air as gas (steam or water vapor). 2  When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding.  Solid water, or ice, is less dense than liquid water.
