what is population destiny
Answer:
Population density is the number of people per unit of area, usually quoted per square kilometre or square mile, and which may include or exclude for example areas of water or glaciers. ... Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2 (38 per sq. mi.).
Answer:
Population density is a measurement of population per unit area, or exceptionally unit volume; it is a quantity of type number density. It is frequently applied to living organisms, most of the time to humans. It is a key geographical term.
Explanation:

What are floodplains?A bottomland, floodplain, or floodplain is a region of land next to a river that runs from the channel's banks to the foot of the valley's surrounding walls and is subject to flooding during times of high discharge. The soils are typically made up of clays, silts, sands, and that have been left behind by floods.
Floodplains frequently have high soil fertility because regular flooding can deposit nutrients and water; some significant agricultural regions, such as the Mississippi river basin and the Nile, heavily rely on the floodplains.
The Mississippi River has a large floodplain covering large portions of midwestern states through which it flows. Ninety percent of this area is no longer flooded annually due to levees designed to hold the water back.
Therefore, option (A) is correct.

Porosity increases:_________. a. when grains settle more closely together after deposition.b. with increasing crystallization between grains in sedimentary rock. c. with the cementing of sediments by minerals from groundwater. d. when rocks develop joints or fractures.
Answer:
The correct solution is Option d (when rocks develop joints or fractures ).
Explanation:
Porosity is observable from descriptive samples taken. The drawbacks of receivable dams are that this is impossible to make true reflection temperature measurements, specific side-wall concrete samples while being often valuable can also result in poor coverage as well as dependence on log-derived porosity seems to have become the standard.As porosity rises, too much wind needs to pass further through most of the shelterbelt, which would be to say the less significant decrease in wind direction.Some other available scenarios have no connexons with the particular circumstance. So this seems to be a reasonable option.
