Population Dynamics and Earth Science Concepts

These flashcards cover key concepts related to population dynamics and various earth science topics discussed in the lecture.

Population Pyramid

A graphical representation showing the distribution of various age groups in a population.

Total Fertility Rate (TFR)

The average number of children that would be born to a woman over her lifetime.

Stage One Population Growth

Characterized by high birth and death rates; often seen in developing countries.

Stage Four Population Growth

Characterized by low birth and death rates; indicative of developed countries.

Rain Shadow Effect

A weather phenomenon where one side of a mountain receives a significant amount of rain, while the opposite side remains dry.

Coriolis Effect

The result of the Earth's rotation that causes moving air and water to turn and twist rather than travel in straight lines.

Health Care Quality and Population Growth

As health care quality improves, populations may experience declining birth rates and increasing life expectancy.

Convergent Boundary

A tectonic boundary where two plates move towards each other, often causing earthquakes and volcanic activity.

Divergent Boundary

A tectonic boundary where two plates move away from each other, leading to the formation of new crust.

Transform Boundary

A tectonic boundary where two plates slide past one another, primarily causing earthquakes.

Soil Texture Triangle

A diagram used to classify soil into different categories based on the proportions of sand, silt, and clay.
