Earthquake is the vibration of the land or the back-and-forth movement of the land. Earth’s vibration is caused by waves of flexible compression passing through the earth’s crust. In other words, it can be said that an earthquake is a disturbance of the earth’s crust, due to which the earth starts moving and the earth’s … Read more
There are the following ideologies about the interior of the earth (1) The innermost hypothesis of the solid German geophysicist Suisse has presented the notion that the melting point of every substance increases with an increase in pressure, but the experiment has shown that this is possible only to an extent. No mineral substance can … Read more
The activities which are related to the movement of lava flowing from the interior of the earth to the earth’s surface are called volcanic eruptions. On this basis, they are divided into two classes. (1) Intrusive (2) Extrusive 1. In penetrating action, the lava of the underground does not reach the surface, but stays below … Read more
Classification of rocks There are many types of rocks. Based on the basic nature and origin of construction, they are divided into three classes- 1. Igneous rocks, 2. Sedimentary rocks, 3. Metamorphic rocks. Related- Explain the composition of the Earth’s Womb. Describe the Principle of Plate Tectonics. Describe the Concept of Normal Erosion Cycle Propounded … Read more
There are many symptoms of relief on earth. Three classes have been made of them. Continents and oceans come in the relief features of the first order. The relief features of the second order include mountains, plains, and plateaus, which are formed by the internal movements of the earth and exogenous waters. The relief features … Read more
Due to the erosion of glaciers, the following features are formed on the mountains- 1 ) Ice depressions – When glaciers descend from high mountain areas, they create many depressions on the mountain slopes, which gradually grow into deep depressions. Over time, these troughs become so deep and wide that glaciers are born and nourished … Read more
The origin of the earth is very mysterious. Different scholars have different views on this subject. As science is progressing, the mystery of the origin of the earth is coming to light.

Earth is a part of our solar system. The solar system is a part of the intermediate rotating arm of the Milky Way galaxy. There are innumerable stars and solar families in the three rotating arms of our ‘Milky Way galaxy’. Many galaxies like Milky Way together form a ‘galaxy cluster’. All the clusters of … Read more
Topographies created by Wind Erosion 1. Kshatrak- Due to the action of air in the desert regions, many rocks appear like a plant called ‘Kshatrak’. This type of texture of rocks is called Chhatrak. There is a canopy of granite near Jodhpur (Rajasthan), which is called Nata in the Sahara desert. These are formed by … Read more
Prof. A. Wegener was a German meteorologist. He proposed this hypothesis to explain the climate of the past. Prominent evidence is available that tropical India, Brazil (South America), South Africa, and Australia were glacierized in the coal epoch. This is possible only when it is assumed that in the past the distribution of climate belts … Read more
