Answer:
The correct answer is: 600,000 years
Explanation:
Half-life is the time which is essential or required to decrease a specific substance to half of its initial amount of the substance. So, if a substance has a half-life of 200,000 years then it means it takes 200,000 years to decrease or change into a new substance and remain half of its initial quantity.
half-life amount
0 20000
1 10000
2 5000
3 2500
total half-life = 3 to 2500 atoms of A
so, the time will be = 3 * 200,000 years
= 6000000
Ocean waters has its own level of density which depends of the climate, temperature and most of all the location where it came from. The more the ocean water absorbs heat the more its density as a result it rises above from cold to hot. So the the water from the Antarctica usually is less dense and then become more dense when it goes to the equator which is more hot.
