Answer:
Summary:
Explanation:
Around 1 million years ago, the first of a few glaciers moved south into what is now Ohio. Approximately 2/3 of the state was covered to their maximum extent. Glaciers scraped a lot of Ohio's surface, including its bedrock. They also left deposits of clay, sand, gravel, and rock as they melted back. During this period, humans appeared in what we now call the "Old World." At some point around the end of the Quaternary Period, groups of people migrated to the "New World," and eventually reached what would later become Ohio.
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.
Answer:
- Shape of the continents
- Fossils of the same species found on continents that are not connected
- Evidence of ice sheets in places that are hot in the present
- Mid-ocean ridges
Explanation:
The continental drift theory is a theory that suggests that the continents are always on the move, thus they change their shape, location, collide with each other, move away from each other etc.
The shape of South America and Africa is one of the evidences. If the shapes of the continents are taken out of a map, and the eastern coast of South America and western coast of Africa are merged, they fit in perfectly.
There are numerous fossils of the same species of animals and plants that have been found all over the world, even though the continents are isolated and separated by water bodies.
In some places that are very hot in the presence, like South Africa, have evidence of ice sheets. In the current conditions that is simply not possible considering that the temperature in this part of the world goes well over 40 C degrees.
The mid-ocean ridges are very nice proof of the continental drift theory. They are one of the evidence that can be observed in the present, where new crust is constantly forming and pilling up, while pushing the old crust sideways further away from it.
