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.
Sources and effects of water pollution. Water pollution can be caused in a number of ways, one of the most polluting being city sewage and industrial waste discharge. Indirect sources of water pollution include contaminants that enter the water supply from soils or groundwater systems and from the atmosphere via rain.Soils and groundwaters contain the residue of human agricultural practices and also improperly disposed of industrial wastes.ources and effects of water pollution.
