<span>When wind and running water gradually decrease in velocity, the transported sediments are deposited over a period of time, and are sorted by size and density. This is because as the velocity decreases, sediments or rocks will accumulate resulting to variety of sizes and a change in density.</span>
Explanation:
The effects on health of transport-related air pollution are among the leading concerns
about transport. Research in recent decades consistently indicates the adverse effects
of outdoor air pollution on human health, and the evidence points to air pollution
stemming from transport as an important contributor to these effects.
This book provides a systematic review of the literature on transport-related air
pollution and a comprehensive evaluation of the health hazards of such pollution. It
focuses on air pollution related to road transport (mostly from urban and suburban
passenger and freight transport) and the risks it presents to human health. It also
considers the entire chain of relevant issues: from patterns and trends in activities that
determine the intensity of emissions from transport, to primary emissions and the
formation of secondary pollutants by means of transportation, and fi nally through to
patterns of human exposure to such pollutants. The discussion of the adverse effects on
health considers the results of both epidemiological studies and toxicological assessments
of biological mechanisms.

1. Niger has twice as many births as deaths per 1,000 people, but the life expectancy is only 52.6, resulting in a young median age. Is TRUE
<u>Explanation:</u>
According to the world bank collections Niger has twice as many births as deaths per 1000 people, but the life expectancy is only 54.6 resulting in a young median age.
Birth rate was recorded as 48.14% It includes number of live births occurring during the year per 1000 population. Italy and Niger have backward masses economics: Italy has a developing people with a high future, and Niger has very young people with heel expectation.
