For divergent boundary: when the crust of the earth fractures it allows magma to reach the surface. For convergent boundary: When one of the converging plates move underneath the other, a process also known as subduction; the new magma rises and can erupt to form volcanos. For the Hotspot: magma pushes through cracks in the crust to form volcanos. Hope this helps!!

Answer:
The difference in the given case indicates that the results are reliable but not accurate. Precision is the tendency of an apparatus to provide repeatable quantities, that is, inaccuracies are minor. The application of standard deviation is generally used as a precision error.
Accuracy refers to the part of an apparatus that provides measures whose average is nearer to the accurate value. It is the reproducibility of an apparatus.
