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
Answer:
There are three types of soil erosion caused by water. They are: Sheet, Rill and Gully.
Sheet Erosion
This type of erosion takes away the top soil over a wide area thereby making it look as though it took a sheet of the top soil. As a result, this is not easy to notice at first glance because the soil from the whole area is gone so there is nothing to compare it to.
Rill Erosion
When water goes in channels and makes lines in the soil a by carrying off the soil that was previously on those lines, that is rill erosion. These channels must be shallow to be considered Rill erosion however because if they are too big, it would become gully erosion.
Gully Erosion
Gully erosion is much like Rill erosion but on a much larger scale. With gully erosion, the channels are much bigger and allow for more soil to be taken. Gully erosion can remove a lot of soil from an area. The Grand Canyon for instance was formed by Gully erosion.
With South Americas Rain forest , it produces 20% of the earths oxygen. Also many drugs used to treat people have come the plants of Amazon. The worlds climate would be much different because ocean currents would be different . Europe would not have the warmth of the North Atantic drift current to keep it warm. It would be more like Siberia .It is located primarily in the southern hemisphere. It is bordered by the Atlantic Ocean to the east and the Pacific Ocean to the west. The geography of South America is dominated by the Andes Mountain Range and the Amazon River (second longest river in the world).Andes Mountains. The Andean Mountains, or Andes, stretch for nearly 7,000 km across the continent, from the top to the bottom. ...
