Tropics and subtropics are climatic belts that have some differences from each other. According to the geographical classification of tropics, they belong to the main belts, and subtropics to transitional. The general characteristic of these latitudes, soil and climate will be considered below.
In the tropics, the vegetation period of the roundtheomed, it is possible to obtain three crops per year of different crops. Seasonal fluctuations in the temperature of the soil are very insignificant. Throughout the year, the soil is warm. The Earth also very depends on the amount of precipitation, in the rainy season there is complete soaking, during the drought severe dragging.
Agricultural farm on the territory of the tropics is very low. Only about 8% of lands with red-brown, red-brown and floodplain soils have been mastered. The main agricultural crops of this territory:
Several types of soil are distinguished in this climate:
The soil of the territory depends on the amount of precipitation. Redfree a characteristic type of soil of wet subtropics. The soil of wet subtropical forests is poor in nitrogen and some elements. Brown soils are located under dry forests and shrubs. In these territories, from November to March, a lot of precipitation falls, and in the summer very few. This significantly affects the soil formation. Such soils are highly fruitful, they are used for viticulture, dilution of olive and fruit trees.
The territory of the tropics is located between the line of the equator and the parallel, corresponds to the latitude of 23.5 degrees. The zone has an exceptionally hot climate, since here the sun shows its maximum activity.
The tropics are high atmospheric pressure, so precipitation is very rare here, it is not for nothing that the Libyan desert and sugar are located here. But not all territories of the tropics are dry, there are wet territories, they are located in Africa and East Asia. The climate of the tropics is quite warm in winter. The average temperature in the hot seasons of the year is up to 30 ° C, in winter 12 degrees. The maximum air temperature can reach 50 degrees.
The territory is characterized by a more moderate temperature. The subtropical climate provides the most convenient conditions for human life. According to the geography of the subtropics are located between the tropics on the latitude between 30-45 degrees. The territory differs from the tropics more cool, but not cold winter.
The average annual temperature is about 14 degrees. In summer from 20 degrees, in winter from 4. Winter is moderate, the lowest temperature does not drop below zero degrees, although frosts are sometimes possible to10 …15⁰ C.
Characterization of the zone
Interesting facts about tropics and subtropics:
- The climate of subtropics in the summer depends on the warm air masses of the tropics, and in winter on cool air flows from moderate latitudes.
- Archaeologists have proven that subtropics are a cradle of human emergence. Ancient civilizations developed on the territory of these lands.
- The subtropical climate is very diverse, in some areas a arid-desert climate, in others, mousson rains are going on for whole seasons.
- Forests in the tropics occupy about 2% of the world surface, but more than 50% of plants and animals of the Earth live in them.
- Tropics support the global supply of drinking water.
- Every second from the face of the earth, a segment of the tropical forest, equal in size to the football field, disappears.
Tropics and subtropics hot territories of our planet. A huge number of plants, trees and flowers grow on the territory of these areas. The territories of these climatic zones are very extensive, so they differ from each other. Located on the same climatic territory, soils can be both fertile and with a very low level of fertility. Compared to the cold territories of our planet, such as the Arctic tundra and foresttundra, the zone of subtropics and tropics is best adapted for human life, the reproduction of animals and plants.
Now I am going to do my breakfast, later than having my breakfast coming
again to read additional news.
This paragraph offers clear idea for the new viewers of
blogging, that genuinely how to do blogging and site-building.
