<h2>
<u>EARTH'S MAGNETIC FIELD</u></h2>
The magnets point North when the Earth's magnetic field has?
<h2>
<u>ANSWER</u></h2>
I think the best answer for this question is Magnetic Reversal or Geomagnetic Reversal.
In geomagnetism, the term "geomagnetic reversal" also known as 'flip', is the process by which the North pole becomes South pole and the South pole transforms into North pole.
<h2>
<u>THE MAGNETIC REVERSAL</u></h2>
The reversals happen on rare occasions when iron molecules start moving towards the opposite direction as other iron molecules around them within the Earth's spinning outer core.
(A)An adaptation is a characteristic that helps an animal survive in its habitat. All animals must be able to obtain food and water, protect themselves from harm, withstand the climate, and reproduce young so the species doesn't become extinct. ... Without their adaptations, the species could not thrive in that environment.
GIRAFFE-That ability – coupled with the tongue's impressive reach and its tough skin – allows giraffes to selectively browse, plucking leaves from among the nasty thorns brandished by many of its preferred food trees, such as acacias.
Explanation:
Since Charles found that the volume is directly proportional to temperature when the mass and pressure remain constant this means that with increase in temperature, there will be increase in volume.
Mathematically, 
at constant Pressure
This equation represents the relationship in Charles' law.
C. Condensation and Evaporation are the two ways in which energy is transferred between layers of the atmosphere.
