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.
Siberia is a vast region, mostly in the territory of Russia, and it is divided into three large regions.
<em>
Western Siberian Plain/Lowland
</em>
Located between the Ural Mountains and the Yenisei River. Occupies the western part of Siberia, and it is mostly composed of lowlands covered with dense forest, the taiga. The northern part is dominated by the tundra.
<em>Central Siberian Plateau
</em>
Located between the Yenisei River and the Lena River. Occupies the central part of Siberia, and it is mostly dominated by a plateau which gains in height on the southern part and is lowering on the northern part. The lower parts are covered with the taiga, while the higher are barren. The northern part is dominated by the tundra.
<em>East Siberian Highlands
</em>
Located between the Lena River and the Pacific Ocean. Occupies the eastern part of Siberia, and the dominated land forms are the mountains, mostly the Kolyma Mountains. Depending on the elevation, the lower parts are covered with the taiga, while the higher are barren. The northern part is dominated by the tundra.
Momma birds hatch an egg and then later the chick comes out of the egg
Answer:
South America's geologic structure consists of two dissymmetric parts. In the larger, eastern portion are found a number of stable shields forming highland regions, separated by large basins (including the vast Amazon basin). The western portion is occupied almost entirely by the Andes Mountains.
