Explanation:
Answer:
All the human causes of global environmental change happen through a subset of proximate causes, which directly alter aspects of the environment in ways that have global effects.
Explanation:
The important proximate human causes of global change are those with enough impact to significantly alter properties of the global environment of potential concern to humanity. The global environmental properties now of greatest concern include the radiative balance of the earth, the number of living species, and the influx of ultraviolet (UV-B) radiation to the earth's surface (see also National Research Council, 1990b).
Answer:
Intensity depends on the distance form the ground and source of energy.
Explanation:
- Earth quake that has an intensity of 1.5 on the Richter scale can be detected only through the seismograph. The earthquake with an intensity of 0 levels on the Richter scale that is below micro will not be felt or rarely felt in scale.
- This can be defied by the Richter scale formula of R=log(IcIn), Ic is the intensity and In is the intensity if the standards earthquake. Hence the difference will be R2−R1=log(I2I1)
