Nitrogen and oxygen are the main constituents of the atmosphere plus water vapour near the surface. Carbon dioxide is present in smaller amounts butgl of course it can have a profound influence on the climate as global warming has shown, Greenhouse gases include water vapour, carbon dioxide, methane and nitrous oxide.
It's one of the following:
1) Social Science
2) Sociology
3) Anthropology
I'm leaning towards social science, but there are far too many variables in what constitutes a probable, correct response to this particular question.
Answer:
Canada's demagraphoc or diversity is a composition that is ethnically heterogeneous, while in the sense that all of Canada's citizens have basically come from many countries or even a orgin and cultural backgrounds. For example on way to depict cultural diversity in Canada is to describe the diversity in Canada in terms if the population size of even those that are not belonging to the charter groups.
Canada is a multicultural society whose ethnocultural make-up has been shaped over time by immigrants and their descendents. Each new wave of immigration has added to the nation's ethnic and cultural composition. Over time, patterns of immigration have shifted. Historically, most immigrants came from Europe.
I hope this helps :)
Answer:
geomagnetic field.
Explanation:
The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.
At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.
Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.
Answer:
I think the ans is option no. B
