Oceanic lithosphere is lighter than continental lithosphere.<br> Select one:<br> True<br> False
Svet_ta [14]

The correct answer is - True.

Oceanic lithosphere is lighter than the continental lithosphere, and this is because the oceanic lithosphere is thinner than the continental lithosphere. The oceanic lithosphere is softer and thinner, and in this parts the geologic activities are much more intense because the high temperature and pressure from the mantle manage to penetrate these parts easier and push magma upwards, creating volcanoes in meantime, as well as lots of earthquakes.

Waters can also carry chemical wastes such as pesticides, and heavy metals dissolved in them. It is common to hear about acid rain as a result of pollution, and it originates as a result of mixing sulphur dioxide and nitrogen oxide with water molecules in the atmosphere.

There are several technological improvements over the past 100 years that have made the availability of clean water to communities a lot easier, and not only depend on boiling water. Filtration is the most common practice, it traps most unwanted particles and microorganisms, but it should be accompanied with chemical disinfection, which uses halogens to oxidize essential celluar structures and enzymes. In the present, chemical disinfection can even be achieved with adding a pill to a specific volume of water.
