Erosion and Deposition are the two important aspects of the evolution of landforms. Every landform has a beginning. Landforms once formed may change in their shape, size and nature slowly or fast due to the continued action of geomorphic processes and agents. Due to changes in climatic conditions and vertical or horizontal movements of landmasses, … Read more
Insolation is the sole driving force behind all the exogenic processes. Solar radiation received in the atmosphere or the surface of the earth is known as insolation that we also call sunlight or solar energy. The gravitational force also affects the exogenic processes resulting in angular displacement or slippage due to molecular stresses. The very … Read more
Volcanism includes the movement of molten rock (magma) onto or toward the earth’s surface and also the formation of many intrusive and extrusive volcanic forms. Volcanoes are the vents from which magma erupts and condenses to form lava. And the process through which volcanoes occur is known as volcanism.
The surface of the Earth is uneven because of endogenic and exogenic forces. The earth’s crust is dynamic. You all know that it has moved and moves vertically and horizontally. Of course, it moved a bit faster in the past than the rate at which it is moving now. The differences in the internal (endogenic) … Read more
The rate of plate movement is determined through the strips of the normal and reverse magnetic fields that parallel the mid-oceanic ridges. According to the theory of Plate Tectonics, the earth’s lithosphere is divided into seven major and some minor plates. And these plates have been constantly moving over the globe throughout the history of … Read more
The layered structure of the Earth was developed through the process of differentiation of the earth-forming materials. The earth was initially a barren, rocky and hot object mostly in a volatile state during its primordial stage. Due to a gradual increase in density, the temperature inside has increased. As s result, the material inside started … Read more
