The answer would most likely be Sea-floor spreading because sea-floor spreading mostly occurs at divergent boundaries.
Answer:
The epidemiological transition has two stages:
- First, the high mortality caused by infectious diseases and malnutrition;
- The second is characterized by chronic degenerative diseases.
Explanation:
Epidemiological transition is understood as the long-term changes in the patterns of death, disease and disability that characterize a specific population and that usually occur along with broader demographic, social and economic transformations.
It is a dynamic concept that focuses on the evolution of the predominant profile of mortality and morbidity, specifically the epidemiological transition implies a change in the predominant direction: of infectious diseases associated with primary deficiencies (for example, nutrition, water supply, housing conditions) to chronic and degenerative diseases, injuries and mental illnesses, all these related to genetic factors and secondary deficiencies (for example, personal or environmental security effect of opportunities for the full realization of individual potentiality)
The epidemiological transition covers three basic processes:
a) Substitution between the first causes of death of common infectious diseases by noncommunicable diseases and injuries.
b) The displacement of the greatest burden of morbidity and mortality from the youngest groups to the elderly.
c) Changes from a situation of predominance of mortality in the epidemiological landscape to another in which morbidity is dominant.

From almost the creation of the first true maps of the Earth, people started seeing how continents would be able to fit together. In particular, people noticed that South America fits almost exactly into Africa.
You should be aware that while world maps were around early in the 1600’s and better defined by the end of the 1700’s, those maps were not ‘public’ but were treated as state secrets. And so it was not till much later that the broader ‘science’ community had access to good quality and accurate world maps.
It is now known that most of the major continental masses can be fit together in a jigsaw process. In fact we now know that the continents were indeed once all joined together as one land mass – the super-continent of Pangaea.
If you look at most world maps you will ponder how this is evidence, as the continents really don’t appear to ‘fit’ together very well. What you need to understand is that the vast majority of maps are drawn using a map projection that has the north and south poles (which are points) are a line the width of the map at the top and bottom. This means that the map distorts the true shape of the Earth’s land and oceans as you love closer to the poles. Some other map projections distort less, but have the map shape looking like segments of an orange. See here for a range of map projections. Check out the way Greenland changes size in each!
