Environmental Exam 2 Questions With Complete Solutions
A Horizon Correct Answers Topsoil rich in organic material
mixed with minerals, crucial for plant growth due to its high
nutrient content and water-holding capacity.
Access to contraceptives Correct Answers Availability and use
can significantly lower fertility rate.
Affluence Correct Answers Wealthier societies consume more
resources per person.
Age Structure and Sex Ratio Correct Answers Influence future
population growth and social dynamics.
Aging population Correct Answers Declining population often
results in a higher proportion of older individuals, leading to a
shrinking labor force and increased economic burden on the
working-age population.
B Horizon Correct Answers Subsoil that contains minerals
leached from the A horizon and is less rich in organic material.
Biodiversity Correct Answers The variety of life across all

Climate regulation Correct Answers Controlling atmospheric
gases and moderating temperatures.
Climate's influence on weathering Correct Answers In warm,
wet climates, chemical weathering is more rapid due to
increased moisture and heat.
Controls of soil formation Correct Answers Influenced by
several key factors including parent material, climate,
organisms, topography, and time.
Cost efficiency Correct Answers Reduce food prices
worldwide.
