Map Projections
This projection is popular for general use because it offers a visually appealing compromise between shape and size.
What is the Robinson Projection?
This is the specific fertility rate—usually 2.1 births per woman—needed for a stable population.
What is the Replacement Level?
This early belief held that diseases were spread by foul odors or "bad air."
What is the Miasma Theory?
This is the term for the total accumulation of a toxin in the tissues of a organisms due to environmental contamination.
What is Biomagnification?
This type of thematic map uses dots to show the exact spread and distribution of a phenomenon.
What is a Dot Density Map?
This specific projection is best for nautical navigation but greatly distorts the size of landmasses near the poles.
What is the Mercator Projection?
The development of vaccines and improved infant mortality rates are two key factors classified under this type of advancement.
What are Medical Advancements?
This pathogen is non-living, must "hijack" a host cell, and cannot reproduce on its own.
What is a Virus?
This is the term for the gradual accumulation of a toxin in the tissues of a single organism over its lifetime.
What is Bioaccumulation?
On a topographic map, this feature indicates a steep incline.
What are Contour lines that are closer together?
This thematic map uses varying shades or intensity of color to represent data variations, like population density.
What is a Choropleth Map?
To calculate the population doubling time, you must divide the number 70 by this figure.
What is the Current Growth Rate?
This type of transmission occurs when a disease is spread via an insect, tick, or flea.
What is Vector-borne Transmission?
These toxins specifically interfere with chemical messenger systems, often disrupting reproduction and development.
What are Hormone Disruptors?
dentifying hazards, estimating likelihood, and evaluating consequences are the core steps of this critical process.
What is Core Risk Assessment?
This specific projection was designed to show more accurate land mass sizes, correcting historical misrepresentations of continental sizes.
What is the Gall-Peters Projection?
This socioeconomic factor is considered the most significant influence in lowering a country's overall fertility rate.
What is Women's Education (or Economic Opportunities for Women)?
These are unique infectious agents composed only of protein, known for causing neurological disorders.
What are Prions?
This type of exposure involves repeated, low-level contact with a toxin over a long period of time, such as years of air pollution.
What is Chronic Exposure?
This type of vaccine uses a modified, harmless virus to deliver protection against a target pathogen.
What is a Viral Vector Vaccine?
This thematic map resizes geographic areas based on the data being presented, such as population or GDP.
What is a Cartogram?
Population dynamics require examining this set of four interconnected factors, including two rates and migration.
What are Birth Rates, Death Rates, Migration Patterns, and Socioeconomic Conditions?
This modern field of study recognizes the complex, interconnected factors—beyond just the microbe—that influence disease transmission.
What is Modern Epidemiology?
This class of toxins damages cellular DNA, often leading to cancer, while Teratogens cause birth defects.
What are Mutagens?
These vaccines use a weakened, living pathogen, while Inactive Vaccines use a killed version of the pathogen.
What are Live Vaccines?
