Answer:
The correct answer is A. If you live in the Midwestern United States or Canada and you experience several days of winter temperatures below 20°C with clear weather, you are undoubtedly experiencing a Continental Polar air mass.
Explanation:
Continental polar masses are air masses that are cold and dry due to their region of origin. Polar continental air masses that affect North America form in further inland Canada.
Both the continental polar air masses and the Arctic air masses are highly stable; the temperature gradient in the lower layers is much lower than the adiabatic one, and stratiform clouds are predominant.

<u>Explanation:</u>
Scientists found the fossils of numerous indistinguishable showing up species on generally isolated main lands. They had two hypotheses for this. Initially, they conjectured that different species grew indistinguishably over the distant, a profoundly improbable idea. The subsequent theory was that the landmasses had been in contact with one another a large number of years prior, and had by one way or another, floated separated.
These landmasses were in contact at some point previously, enabling species to wander unreservedly, bite the dust, be covered, and become fossilized over these central lands.
