We know that the poles had changed positions in the past, because of the arrangement of the crystals in the rocks made out of metal. The crystals of the metals act like the needle of the compass when the rock is cooling off and forming, they turn into the direction of the strongest magnetic field on the Earth, which is the North Pole. So by studying the rocks that are made out of metals and see the crystals arrangement and also estimate the age of the rocks, the scientist can precisely tell how has the North Pole been moving throughout time.

<u>Answer:</u>
Hazard factors for these TB-related results incorporate structures, practices and different infections ordinarily connected with <em>poverty - packed living or working conditions, poor nourishment, smoking, liquor abuse, diabetes, presentation to indoor air contamination and HIV.</em>
<u>Explanation:</u>
Tuberculosis (TB) is known to lopsidedly influence the most monetarily impeded strata of society. <em>Numerous examinations have evaluated the relationship among neediness and TB,</em> yet just a couple have surveyed the direct budgetary weight TB treatment and care can put on family units.
Patient expenses can be especially oppressive for <em>TB-influenced families in sub-Saharan Africa where destitution levels are high;</em> these expenses incorporate the immediate expenses of medicinal and non-therapeutic consumptions and the roundabout expenses of time using social insurance or lost wages.
<em>So as to extensively survey the current proof on the costs that TB patients acquire, we attempted an orderly audit of the writing.</em>
