Types climatic zones

1. Tropical zone
There lies tropical region up 30 degree latitude n both the hemisphere. Since the rays are straight here it is always hot but rainfall depends according to the place. On the basis of temperature this zone can be divided into the following climatic regions.




a. Mediterranean region
As the sun rays are vertical in the region between 5 degree to north and south of the equator, it is very hot all over the year. As a result of heat, the surface area becomes hot. In this region there is no seasonal change. The days and night are of equal time. 90 percent of the living species are found here.



b. The region of hot desert
From 20 to 30 degree latitude both the hemisphere, in the middle and the southern parts of continent it is usually very hot and dry. The big desert like Sahara, Atacama and Kalahari lies in this region. It is very hot at day time and cold in night. On the plants there are cactus, and other busy and thorny plants. The animals like camel, fox etc. can survive there.

C.Tropical woodland

The extended grassland found in between 5 degree south to 20 degree south latitude is called savan . It is the zoo of the world because here are found all the types of animals. It is warm and rain also fall. the rain fall takes in winter.The animals like zebras, giraffe, and all others wild animals are found here.



d. Tropical monsoon

The climate in between 5 degree to 30 degree latitude in both hemispheres is known as tropical monsoon. It is hot and rainfall in summer and winter is cold. The wild animals like tiger fox jackal elephant are found. There are ever green plants in this area.


Temperate zone
There lies temperate zone in between 30 to 50 or 60 degree latitude in both the hemisphere. It is neither hot nor cold. There are 3 types of regions of it.


a. Mediterranean
It is hot, drying summer and warm and wetting winter. In summer, rainfall does not take place. We notice such climate around Mediterranean sea In European countries, center chili, in south America, C.A etc. The trees here have long roots, thick barks and small and smooth leaves.






b. Temperate grassland
In the inner part of the continents the climate reaches up to 25 degree Celsius in summer and in winter as it is very cold. The soil is very fertile because the humus increases the soil fertility.



c. Temperate woodland
The climate around the Saint Lawrence River in Western Europe and North America is very useful for health. Because of the effect of the ocean, there is small yearly temperature difference .Natural vegetations are of deciduous nature. The developed areas of Britain, Norway, Sweden, France, Germany, USA and Canada are in this zone.





Polar Zone
In this zone the sun rays doesn’t fall the whole winter and the whole winter is dark. Water in the sea freezes due the coldness. No one lives permanently in the Antarctica. Northen polar zone is frozen with ice.As the heat increases in the Summer , to some extent,the land doesnot get frozen and some varieties of plants and fl0owers grow there.Greenland Canada, Scandinavia lie here. There is similar climate in the various part of Russia.There are people who live permanently here.They have their own lifestyle.Houses are made up of stones and in winter they are made up of the ice blocks named igloo.To the south to the Tundra there is a coniferous evergreen forest. It is very cold here. This forest is extended from east to west in Canada and Siberia in Asia. It is extremely cold here and therefore, there is less cultivation.
