Question

why is the rule of 70 useful in environmental science? it shows the change in temperature. it helps predict how fast the population will shrink. it helps estimate how fast the population will double.

Explanation:

The rule of 70 is a quick - calculation method. Dividing 70 by the growth rate (in percentage) gives an estimate of the time it takes for a quantity to double. In environmental science, it can be used to estimate population growth of species or other exponentially - growing factors. It has nothing to do with temperature change or population shrinkage.

Answer:

It helps estimate how fast the population will double.
