False
Explanation:
In the orange country's water treatment system techniques like micro filtration , and ultraviolet ( UV ) , reverse osmosis (RO) disinfection with hydrogen peroxide are used for purification . Generally at the source polluted water is first micro - filtered for the removal of small suspended particles bacteria , protozoa , and harmful virus from water . The water is then filtered via RO , which removes salts , pesticides , viruses and most organic compounds are passed in the presence of the forced water via thin plastic membrane , and in the final stage , the water is treated with hydrogen peroxide and UV light as a precautionary measure.
D. high and low levels of silica in the different type of lava.
Explanation:
The volcanoes have different types of explosions. Some tend to be highly explosive, some less explosive, some don't have explosions at all, while some have combinations of different eruptions. The reason for this diversity in the eruption types is mostly the composition of the magma, or rather how high is the silica content in it.
Basically, the higher the silica level in the magma the higher the explosiveness, and the lower the silica level the lower the chances of explosiveness. This is the case because the higher amount of silica makes the magma thicker, so the gasses are trapped and they explode, while when the lower silica content makes the magma less thick, so the gasses are not trapped and explosions are lacking.
