” It’s a joke, of course, and the fact that he says it so often has itself become a joke. As it turned out the key to giving up that last bit of cheese — which I clung to for months — was simply deciding to do so. Being vegan doesn’t have to be more expensive, but it will be.
Radioactive elements, either of natural origin or created by nuclear testing, can be used to date the layers of ice in the cores.
Some volcanic events which were sufficiently powerful to have distributed material around the globe leave a signature in the ice which can be detected in many different cores, allowing synchronization of the time scales between two different locations.
In the case of rapid growth, we may choose the exponential growth function: [latex]y=_^[/latex] where [latex]_[/latex] is equal to the value at time zero, is a positive constant that determines the rate (percentage) of growth.
We may use the exponential growth function in applications involving doubling time, the time it takes for a quantity to double.
Impurities in ice cores may depend on location; for example, coastal areas are more likely to include material of marine origin, such as sea salt ions.
