Convection<span> in the solid mantle drives the many processes of plate tectonics, including the formation and movements of the continents and oceanic crust.</span>
The volume is 155,000,000.
<span>And igneous rock sample is about 250,000 years old. Would you use uranium-lead radiometric dating to find its age?
Yes, wikipedia says "</span><span>It can be used to </span>date<span> rocks that formed and crystallised from about 1 million years to over 4.5 billion years ago with routine precisions in the 0.1–1 percent range.</span>"
Therefore, 250,000 years can be compared
Answer:
