Geographic variation was the study or examination that living things which are relatively similar are different because of their habitat and geography was dissimilar. Comparable organisms parted ways by physical features and global positioning.
It depends on the position of the species a cline can happen. This can relate to a specific one of two or more substitute forms of a genetic factor that arise by transformation and are found at the same place on a chromosome which will assist in surviving of a different but reachable geographic location.
The atmosphere is earths largest deposit of carbon .
Very globalized duhhhhhhhh
Air pollution is caused by multiple factors, we can divide them in two groups, natural and human caused.
From the natural, the once that cause the biggest air pollution are the volcanoes with their release of ashes and toxic gasses into the atmosphere, the methane released from the melting permafrost around the polar regions and Siberia, and the cattle with the release of methane gas...
From the human caused pollution of the air we have the burning of the fossil fuels, dust from the building activities, poisonous gasses that releases the industry, burning of wood in the households (and all sorts of other stuff alongside it)...
Answer:
Latitude - is a determiner of agriculture because it establishes the general seasonality of the place, and the differences in sunlight received depending on the time period.
Ocean temperatures - the ocean is a force that makes the climate milder. Warm ocean temperatures mean warmer climates, which tend to be better for agriculture, while the opposite occurs when ocean temperatures are low.
Wind currents - wind currents can determine precipitation or the abscence of it. It can also bring harmful events for agriculture like dust storms, or tornadoes.
Elevation - higher elevations tend to be less fertile than lower elevations because they are colder. However, this is not always the case, and some high altitude regions are very fertile, for example, the Central Valley of Mexico.
