In geology, the Radioactive dating is significant because its provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change.
<h3>What is a Radioactive dating?</h3>
This refers to the technique that is used to know the date of materials such as rocks or carbon in which the trace radioactive impurities were selectively incorporated when they were formed.
It determines the dating of rocks and minerals through the use of a radioactive isotopes, it is also useful for igneous and metamorphic rocks that cannot be dated by the stratigraphic correlation method.
As the carbon dating helps to determine the age of an object containing organic material by using the properties of its radiocarbon, it is considered a poor tool for finding the age of the dinosaur skull in the purple layer because the collagen in the dinosaur's bone has usually long since decayed away and is therefore unavailable for radiocarbon dating.

Answer:
True
Explanation:
It's true that old vehicles like the ones found in Africa and in other poor countries contribute a lot to the air pollution.
But it's far from the only reason... it's probably not the most important reason for most countries either. The main reasons would be big factories without any air pollution control, and the total eradication of air-purifying forests.
This is mostly the doing of the industrial countries... either by colonisation or by exporting factories in places where they had lower environmental controls to attract investments.
The crate has a volume of 80 cu feet (4*5*4) and each cu foot needs 2 bags so 160 bags are needed.
