Answer:
Cold air masses are drawn to the equator. Warm air masses gravitate towards the poles. They move diagonally because to the Coriolis effect. Many air masses are moving northeast across the United States. The global winds also blow in this way.
Explanation:
Unconfined aquifers more vulnerable to pollution from runoff and underground seepage than confined aquifers because as water seeps into the soil, contaminants on the ground surface may enter the unconfined aquifer.
<h3>What is Unconfined aquifers?</h3>
- Unconfined aquifers, sometimes known as "water table aquifers," are more susceptible to surface pollution contamination than confined aquifers.
- An aquifer with a water table, also known as an unconfined aquifer, has its upper water surface at atmospheric pressure, allowing it to rise and fall.
- Unconfined aquifers are found underneath a permeable layer of soil, whereas confined aquifers are covered by an impenetrable layer of rock or clay.
- Aquifers can be formed by a wide variety of sediments and rocks, including gravel, sandstone, conglomerates, and fractured limestone.

From the standpoint of geography and demography, all the people who live in a particular area would be considered as a population
In Geography, the population is the total number of people, who reside or live in a particular location. Usually, the population varies in sizes, structure, distribution, and composition.
<h2>Further Explanation</h2>
However, there are several factors that determine whether a population will increase or decrease.
Some of these factors include
- Immigration
- Emigration
- Birth rate
- Death rate
- Agricultural changes
- Impact on urbanization
- Education
Movements of people mainly from rural to urban areas are one of the major factors that affect changes in population growth. The birth rate of a country will rise when people move from the rural to urban while the death rate also tends to fall.
The birth rate will increase because the people moving in will have access to basic medical facilities and will also result leads to a reduction in the infant mortality rate.
Education is also a factor in determining birth and death rate; it determines the level of population growth. Some hygienic programs can reduce the death rate and also educating the people on family planning such as the use of contraceptives are also one the ways that can reduce the birth rate.
