As we study the main components of soil that is (sand, silt, clay) that come from lithosphere by the Exogenic forces like climatic or Claimozonic process like weather and erosion.  Soil can be group into part one is physical and other one is chemical properties.  Physical Properties Texture Structure Porosity and permeability Chemical Properties PH values Humus and collouds Soil texture The structure describes the manner in which soil particles are grouped together into layer, pieces or aggregates.  Properties of soil                       Diameter                                                        (mm)  Gravel                                            1  - 2 Sand                                              1 - 0.05 Silt                                               0.05 - 0.005 Clay                                      Less than 0.005                            Soil's Name         Sand           Silt        Clay Clay     

As we know that there are number of spare likely thermosphere atmosphere Hydrosphere and biosphere which collectively give birth to soil. Its means soil is a function of lithospheric atmospheric Hydrospheric and biospheric process and soil is the mixture and outcome of this four spheres. Getty image Lithosphere ( parent material)  Parent materials means some material from lithosphere circuits and silt and clay brought down by lithosphere. Atmosphere Means different gases come between the words of tabs on the basis of pedology is comes. Pedology The scientific study of the morphology competition and spatial distribution of soil including the classification and use.  Pedogenesis The formation of soil by natural process from parent material Parent material means the rock of Mountain plateau and plain Cryo pedagogy The scientific study of formation and characteristics of soil in Perigalacial reasons Tundra and Taiga region are most suitable area for it

INTRODUCTION On our planet and earth there are two type of landscape one is natural and other one is culture or man made things present. In natural there are different gradient like lithosphere, hydrosphere, atmosphere and biosphere, while in cultural landscape all the things are made-up by man.  Those after studying lithosphere, Atmosphere, hydrosphere we have to study the biosphere.  Biosphere Getty image Biosphere means the geography of the biotic things where biotic may be micro organisms found in soil and large material such as plants and animals.  What is biosphere  Biosphere is very important aspect of geography. It is also called bio-geography which has significant place in the geography syllabus.  TYPES OF BIOSPHERE Biosphere is divided into two parts one is soil also called pedo-sphere and other one is vegetation(biosphere).  What we are going to learn in our next some post here I mention all the things.  SOIL - WE LEARN IN OUR NEXT ARTIC
