Infinix Hot 8 It is very important news for those who are going to buy a smartphone under low price. Now it is possible to buy a 4g smartphone under 7000 along with long lasting battery. Because flipkart is going to lunch a very good looking and gaming mobile called Infinix Hot 8 the price of which is only Rs 6999 in flipkart.         Some highlight features are given below :- 1. This Smartphone has 4g RAM along with 64 gb ROM i.e., external memory. 2. This smartphone has very big hd+display of 6.52  inch. 3. This has a long lasting battery of 5000 mAh Li - ion polymer battery. 4. It has Helio P 22 processor ( MTK6762).       Flipkart is going to lunch this mobile in 22nd January at 12 noon. 

EXOGENETIC FORCE The exogenetic forces or processes also called as denudational processes or destruction forces or processes are originated from the atmosphere. These forces are continuously engaged in the the destruction of the relief features created by the endogenetic forces through there weathering erosional and depositional activities. Exogenetic processes are, therefore, planation processes. Denudation includes both weathering and erosion where weathering being a static process includes the disintegration and decomposition of rocks in situ whereas erosion is dynamic process which includes both removal of materials and their transportation to different destinations. Weathering is basically of three types viz. (a) Physical or mechanical weathering, (b) Chemical weathering and (c) Biological weathering. Weathering is very important for the biospheric ecosystem because weathering of parent rocks results in the formation of soils which are very essential for the sustenance of the

Glacier and its Types Glacier:    The moving ice mass downslope under the impact of gravity is called Glacier. About 10% of the Earth's surface is now covered by glaciers. About 2-3 million years BP glaciers extended over almost one third of the Earth's lithospheric surface. Glaciers are formed due to accumulation of ice above Snow Line under extreme cold climate. Snow Line is generally defined as a zone between permanent and seasonal snow. In fact snowline denotes that height above which there is permanent snow cover and thus it corresponds to the the level where average temperature is always below freezing point during the warmest month of the year. The snow line is at the lowest height ( 0 m or sea level ) in the Polar region and and increases equatorward where it tends to between 500 to 6000 m. The estimated number of all types of glaciers all over the world ranges between 70,000 and 200,000. The areas of accumulation huge volume of ice are called snow-fields which g

Fluvial works Erosional work of river :      The word erosion has been derived from the Greek word 'erodere' which means to gnaw. Fluvial erosion is a dynamic process which involves the removal of Geo material from the rocks. The factors controlling the erosional work of river include channel gradient and volume of water, velocity of water, river load etc. The quantity and angularity of erosion tools largely control nature and magnitude of fluvial erosion.        The following relationship may be identified between the rate of fluvial erosion and river load. 1. Erosion becomes minimum in the absence of required amount of river load. 2. Erosion also becomes minimum when the river has maximum load. 3. Erosion becomes minimum when the river carries load according to its transporting capacity.       Besides river load velocity and channel gradient are also important factors which effectively control fluvial erosion. The velocity of water flow depends

Folded Mountains    Folded Mountains are formed due to folding of Crustal Rocks by compressive forces generated by endogenetic forces coming from within the earth. These are the highest and most extensive mountains of the world and found in all the continents. The distributional pattern of folded mountains over the globe denotes the fact that they are generally found along the margins of the continents either in north south direction or East West direction. Rockies, Andes, Himalayas etc. are the examples of folded mountains.    Folded Mountains are classified on various bases as follows.       1. Folded Mountains are divided into two broad categories on the basis of the nature of folds. (a) Simple folded mountains with open folds - Such Mountains are characterized by well developed system of anticlines and synclines where infolds are arranged in wave like pattern. (b) Complex folded mountains represent very complex structure of intensely compressed folds. Such Complex s

Interior structure of the Earth  : 1. The Crust  :-                            The crust is the outermost layer of the earth. The thickness of the crust is varies under oceanic and continental areas. The thickness of the oceanic crust is around 5 km, where as the thickness of the continental crust is around 30 km. It should be note here that the crust is thicker under mountainous areas. It is around 70 km thicker under the Himalayan region. The average density of the outer and lower crust is 2.8 and 3.0 respectively. The difference of density between the upper and lower crust is because of the pressure of supperincumbent load. The average velocity of P waves in the upper crust is 6.1 km per second while it becomes 6.9 km per second in the lower crust. 2. The mantle :-                            The portion of the interior beyond the crust is called the mantle layer. The mantle extends from Moho's Discontinuity to a depth of 2900 km. Moho's Discontinuity is boundar
