Answer: Magnetic susceptibility is way to measure how attracted or repelled a material is when exposed to a magnetic field.
Explanation: Magnetic susceptibility is related intimately to magnetization, since this is the procedure of exposing some material to a magnetic field itself, turning it permanently or momentarily magnetic. A magnetic field has <u>permanent dipole moments</u> between two magnetic materials, creating <u>electric currents.</u> Two examples of its applications are for paleomagnetic studies in geology and also structural geology.
The vast pollution which occurs globally can have a significant impact on air quality on a local scale. The reason for this is quite simple: polluted air can easily get trapped beneath a cloud cover, or be literally "blown" away to other locations, and when much polluted air gets accumulated, it can have devastating heath effects on a local population, not just to humans, but to animals and plants as well. Overall, the vast global pollution can effect the smallest of regions on an unprecedented scale.
Basically the Earth is layered because of gravity. The earth formed in the molten state. The liquid iron which is very dense fell to the center. The rest of the earth is made up of silicate materials with SiO2 being the main component.
hope this helps!
