Answer:
Maritime Polar air masses are cool, moist, unstable thus found over Arctic basin and greenland ice caps.
Explanation:
- Air mass is the volume of air defined by temperature and water vapor. Covering hundred and thousands of miles. Cooler are being found over the arctic.
- They move southwards along the Rockies into the plains then eastwards. These air masses collect warm and mist winds, originating in north Atlantic. The center of the air mass has high pressure and surrounded by lower air pressure at higher latitudes.
- Antarctica and arctic circle are dominated by such air masses
Answer:
b
Explanation:
tilt, because day/ night is due to Earth's rotation
Answer and Explanation:
The offshore or coastal or littoral regions have very rare experience of extreme variations in temperature, this is due to the fact that the heat capacity of water is higher than it is on the land which means that it takes longer time for water to vary its temperature i.e., it takes longer time for water to get heated or be cooled. Therefore, it goes with the established fact of heat capacity of water that the regions far away from the ocean or littoral regions experience extreme temperature variations as compared to the areas closer to the coastal regions and these areas have moderate temperature i.e., neither too hot in summers nor cold in winters.
Answer:
The great varieties of minerals on the Earth are classified by mineralogists into a small number of groups on the basis of : The negative ion or ionic group in their chemical composition.
Explanation:
Minerals are classified based on their chemical properties. The anion, a negatively charged ion that generally comes at the end of a mineral's chemical formula, is the fundamental foundation for classifying minerals, with the exception of the native element class. Cations are ions with a net positive charge because they have fewer electrons than protons. Anions, on the other hand, have a net negative charge because they contain more electrons than protons.
Hope this helps! :D
