Answer
<u>A rapid improvement in standard of living can mean rapid economic growth with increased population in towns resulting to damaged environment in form of pollution.</u>
Explanation
When the standard of living is associated with rapid growth of the economy, a common scenario is migration of people to urban areas to work and operate businesses. The urban areas will experience increased populations with inadequate housing. The environment will be suppressed because more forests will be cleared to give out spaces for new housing projects. In addition to that, the pollution levels will increase because more wastes will be generated.
Explanation:
Possibilism is a theory arising from geography, which defines nature as a non-determining factor for the evolution of societies, that is, despite the fact that nature provides certain resources or difficulties for societies, possibilism believes that man can modify the environment environment to develop.
Therefore, a benefit of the concept of possibilism for humanity, is that this concept opens greater possibilities for man to survive in the already existing conditions of nature and modify it for his well-being, that is, man is able to adapt the conditions from the environment to the social benefit, through techniques, knowledge and technologies, which will promote the social, cultural and economic development of a given location.
Most likely due to the movement of plate tectonics. They are plates of earth under the ocean that move occasionally, over the years this is probably what happened. Plate tectonics are also the cause of most earthquakes and even tsunamis. Erosion could also play a factor in this as well.
The one that best help the scientists to study the generation of Earth's magnetic field would be : A. Comparison rotation of the earth's core and Crust
The Earth's magnetic field currently tilted at the angle of about 10 degrees with respect of Earth's rotational axis
hope this helps
