Answer:
A total number of people within a continent
Explanation:
The population growth in a particular place is reflective of how the population is changing positively over a period of time.
It is simply the change in population with with time.
- The total population through a given time frame and within a geography is very important for population studies.
- The population growth formula is given as:
P = P₀ eᵇⁿ
P is the total population
P₀ is the starting population
b is the growth rate
n is the time
The index fossils are fossils that are found in the rock strata of certain geologic period, but they are also fossils that are very common and can be found in numerous places around the globe.
Because they can be found all over the globe, and they are indicative of certain geologic period, the geologists have started to use them as a simple way of determining the age of the rock strata. While this method can not provide the geologists with an accurate year for the formation of the rocks, it is still able to determine the relative age of the rocks. By determining the relative age with such ease by using the index fossils, the geologists are able to immediately make conclusions about the rock strata, have basic information about it, and largely be aware of the processes that formed them and influenced them.
