Respuesta :
If the Mid-Atlantic Ridge is spreading 4cm/year, then it took 83000000 years for the Atlantic Ocean to separate Canada from Ireland.
What is the conversion of units?
The conversion of units by using dimensional analysis is the changing of the unit of a particular parameter from one form to another.
This technique takes a logical approach when solving and converting from one unit to another.
From the given information:
- A rift can be produced between 1cm/yr to more than 10 cm/yr
The separation between Canada and Ireland is roughly 3320 kilometers.
Then, the number of years it took the Atlantic Ocean to separate Canada from Ireland is:
[tex]\mathbf{= \dfrac{3320 \ km }{ 0.00004 \ km/year }}[/tex]
= 83000000 years
