It is false that the total fertility rate is a measure of the number of children that would be born if all women lived to the life expectancy age for the given country in which they live.
<h3>What is total fertility rate?</h3>
- The number of children that would be born to each woman collectively if she were to survive to the end of her childbearing years and have children in accordance with the current age-specific fertility rates is the total fertility rate for a given year.
- Children per woman is how it is stated. The sum of age-specific fertility rates, which typically apply to women between the ages of 15 and 49, is used to directly calculate the total fertility rate, or five times the sum if the data are provided in five-year age groupings.
- We can predict how a population might increase, decrease, or stable over time by using the TFR, mortality, and migration projections.
- The total fertility rate can be used to forecast future age distributions within a population as well as other demographic changes.

Answer:
Explanation: The lab allowed me to model and observe stream and river processes. Using a virtual model, I compared low and high velocity streams or rivers, low and high gradient streams or rivers, and low and high volume streams or rivers. I found that higher velocity streams or rivers can cause more erosion, as do higher gradient and higher volume streams or rivers. Not only did these factors move more small sediment, they also moved larger pieces of sediment.
