You can install some noise barriers at the sound source , and also plant some trees which are a kind of good muffler. Or at least you can wear the earplugs.
Different technologies have been used in the prevention of water pollution . For example , when the quality of the water is not bad and there are only some pollutant of suspended solids , we can only use some physical methods , such as grilling , to treat the pollution , which is called the … Read more
It is said that everything has two sides.The chemistry help to develop the modern science , but it also causes the environmental chemical pollution.
That is because the clinical thermometer is more accurate than the laboratory thermometer . And the clinical thermometer can be read out of the body ,while the other one can not . Beside these ,the measurement range of the clinical thermometer is only about around the normal temp of human body while the other one … Read more
As an individual, all we can do is only the petty things, such as saving water, paper and not using plastic sacks - which may seem trivial, but if everyone does this, our oceans and land will become more beautiful.
The buoyancy is formed when the solid is submerged in the liquid. And the upthrust is formed by the extrusion between different crust in the surface of the Earth.
The temperature is higher than anywhere in the earth , but the pressure above the equator is lower than the surrounding .
