Explanation:
The most important information on a topographic map that can be used to compare the steepness of slopes on the map is the contour.
- Contour lines are lines on a map that joins places having equal elevation on a map.
- The nature of the landform in an area can be inferred from the contour lines.
- Where contour lines are close together it signifies rapidly changing topography and thereby, a very steep slope is inferred.
- Where contour lines are wide apart, it signifies a gentle slope.
Answer:
This theory was developed in 1929 by the American demographer Eric Lofstedt
Explanation:
- Demographic transition s models that show how the population of any country moves from traditional to modern society i.e shift from high birth rate to low birth rate with improvement ion stands of living.

Second Stage: Very rapid increase in population. i.e Agricultural revolution
Third Stage: Increase slows down. i.e Urbanization stage.
Fourth Stage: Falling and then a stable population. i.e Disease control
Fifth Stage: Stable or slow increase.

- Various nations have different demographic transitions and shift occur when societies advances and moves up the ladder of growth. LInking society fertility and economic development.
