The topmost layer of the earth (aside from the atmospher) would be the crust. It is made up of tectonic plates that move in different directions. The collisons and abrasions made by these plates sliding and crashing into each other means that mountain ranges pop up like wrinkles, and continents can move around over time. This happens over millions of years. good luck !
The answer would be (-13,-4) if you wanted to do it without a graph all you have to do is subtract so -8 - (-3)= -5 so five to the left and -9 - (-5)= -4 so four down. Hope this helps! :)
It is also called the real density and is a measured by the total number of people divided by the total land area.
While the population density is the measurement of the population per unit of area or unit volume and is frequently used to a living organism and is a key variable to measure of the population characteristics and pattern.
