When the prediction about the population of a country is going to increase in next two decades is made , what might be the result of the population increase is option B which are Basic needs, such as food and water, will be scarce.
<h3>What is overpopulation?</h3>
Over population serves as the increase in the number of the population of a region which bring about the scarce of resources among them.
Therefore, what might be the result of the population increase is option B which are Basic needs, such as food and water, will be scarce.

Air pollution results from incomplete combustion of impure fuels.
Two-stroke engines emit 20% to 50% of their fuel unburned in the exhaust, but also a considerable amount of oil too. Air pollution is higher in this cases and includes a considerable amount of particulate matter.
Answer: 30 year
Explanation:
The normal high temperature for a given day determined by the temperature of a place averaged over a period of time, often 30 years. This is also described as climate information. Climate information includes the statistical weather information that tells us about the normal weather, and also the range of weather extremes for a location. Most weather forecasters rely of past weather to predict the normal high temperature of a given day.
The average high or low temperature is the normalized high or low temperature for at least a 30 year period. Therefore, an average high is a statistical average. Records need to be kept at least 30 years for an average high temperature, for the information to be statistically meaningful.
Answer:
The Earth’s crust is not a solid shell. It is made up of thick, interconnecting pieces
called tectonic plates that fit together like a puzzle. They move atop the underlying mantle, a really thick layer of hot flowing rock.
By examining evidence such as similar rock layers in various places, fossilized desert
belts, the distribution of fossils, and the physical shapes of continents, scientists
have concluded that the Earth’s continents were once all connected to form a
“supercontinent” called Pangaea that was surrounded by an enormous ocean. In
this activity, students will use the different kinds of evidence to reconstruct how
the Earth may have looked approximately 220 million years ago.
