Answer:
b. There is insufficient contrast in surface type (land vs. ocean) in the middle latitudes.
Explanation:
The sources of air masses can be produced or at very high latitudes because they can carry big amounts of air from the top of a mountain till the bottom by the differences of pressure and temperatures. This kind of air mass is called continental.
In the other hand, in a low latitude, the air coming from the sea, try to reach higher latitudes, again, by pressure and temperatures differences. These kind of air masses are called maritime.
Hope it was useful.
Answer:
They are weather systems that happen to spin in a counterclockwise direction in the Northern Hemisphere from low pressure points. They form between two big cold fronts when their temperatures are very different compared to each other. These air masses will blow past each other in opposite directions when it is formed.
D) It was in the middle of an economic boom
The soil that occurs in regions with extreme wet and dry seasons is known as "black soil."
Black soil:
- Chernozem is another name for black soil.
- It is largely composed of humus, phosphoric acid, phosphorus, and ammonia.
- Exceptionally small or clay-like particles constitute black soils.
- Deep gaps form during warmer weather, resulting in appropriate aeration.
Black soil characteristics include:
- It is extremely fertile and has a clay-like texture.
- At 25°C, the pH of black soil ranges from 7.2 to 8.5.
- The soil has high levels of potash, calcium, and magnesium but low levels of nitrate and phosphate.
- It is often soft when damp but hardens as it dries.

Answer:A. Temperature or thermal subversion
Explanation:
Temperature subversion occurs when a cool air layer forms under a warm air in the
Troposphere
