Why is the temperature of oceanic crust slightly lower than continental crust?.

1 answer:

3 0

Answer:Continental crust is much thicker than oceanic crust (averages between 20 to 25 miles thick), but is actually slightly less dense than oceanic crust. The main type of rock on continents is called granite. So if these two types of crust were to collide into each other, what do you think would happen to the oceanic crust? As a whole, notice that the crust is lighter than the mantle

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

pav-90 [236]

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.
