The element found in period 4, group 2 is zirconium, Zr
<h3>the best estimate for earth age is based on radiometric dating of fragment from the canyon dialo iron meteorite from the fragments scientist calculated the relative abundance of element that's for maid as radioactive Uranium decayed over billion of years</h3>
Answer:
B
Explanation:
An orange is still a plant and the child is drinking it, but it is still consuming it, so I'd say that that's still eating nonetheless.
The correct answer is - False.
To trace the correlation between the rock layers by using fossils can be a big mistake, though occasionally it may provide the proper information, still it will be relying on luck.
The case is actually the other way around, the fossils can be correlated by using the rock layers, because each layer of rocks represents some time in the geologic past.
The fossils, on the other hand, are much more easy to be moved through the layers over time, because there can be disturbances, adjustments in the crust, or the rocks can change their composition under the influence of multiple factors. All of that can contribute to the fossils ending up at places where they aren't expected to be, so using them to correlate the rock layers will not be a very useful method.
