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.
Causes of Water Pollution. Let us now study the causes of water pollution. 1. Industrial waste: Industries produce huge amount of waste which contains toxic chemicals and pollutants which can cause air pollution and damage to us and our environment.They contain pollutants such as lead, mercury, sulphur, asbestos, nitrates and many other harmful chemicals.ollution of water occurs when substances that will modify the water in negative fashion are discharged in it. This discharge of pollutants can be direct as well as indirect. Water pollution is an appalling problem, powerful enough to lead the world on a path of destruction.
