Introduction to crystallography

Crystallography: The subject of crystallography is included in mineralogy, which discusses crystals and laws that govern their growth, external shape, and interior structure. Very few minerals are crystalline, but most of the minerals are found in crystalline form. When minerals crystallize under favorable conditions, they take the form of crystals. Thus the crystal form of …

What is an earthflow? Different types of earthflow

In the previous post, we discussed the concept of landslides, their causes, and different types of landslides. Landsliding is the movement of rock, earth, or debris down a sloped section of land. The study of landslides is important because they affect many types of engineering works, particularly highways and railways. Loose rock material ordinarily creeps …

Land Slides and their causes

Landslides: When a mass of earth or rock slides down the slope along a definite zone or surface, the movement is called Landslide. The primary factor behind this movement is gravity and is facilitated by moisture, which acts as a lubricating agent. The landslide starts with slow movement along a slip surface, followed by a …

Different Celestial Bodies and Natural Phenomena.

Galaxy: A galaxy is defined as a huge congregation of stars which are held together by the force of gravity. Galaxies numbering millions lie scattered in the Universe like dots. The galaxies are the clusters of stars. These can be spiral galaxies, elliptical galaxies or irregular galaxies. Out of these, the spiral galaxies are large …

Bridge Engineering

Bridges: Bridges form an important part of the transportation rules. They are constructed across the rivers to carry highways and railways. In a country roads and railways often follow the shortest route and therefore, their alignment is determined much before the construction of bridges. As a result, the site of a bridge does not allow …

Introduction to Human Geography.

technocentrism

Human geography is that branch of Geography which is concerned with the spatial differences and organisation of human activity and its inter-relationships with physical environment. Human geography is separate from physical geography and economic geography. It studies topics like man and his habitat, environmentalism, possiblism, world population, structure of population, migration, world society, culture races, …

The Solar System and Its planets.

difference among the inner and outer panets.

The Solar System comprises of the Sun and eight planets (excluding Pluto) which revolve around it in fixed orbits. The Sun is the center of the Solar system. Distanc-wise Mercury is closest to the Sun followed by Venus, Earth, Mars, Jupiter, Saturn, Neptune. Pluto was excluded from the Solar system by the Scientists and was …

Scope of Geology

Geology is of practical importance to mankind. It plays a very useful part in the search of coal, petroleum, minerals used as atomic fuels. It is directly concerned with the ore mineral, industrial minerals and mining industry. The importance of geology has also been recognized in the field of engineering. Many engineering projects such as …

What is Geology. Its main branches.

what is geology.

Geology is a Science which is devoted to the study of the Earth. It deals with all the features of earth’s surface, its origin, composition, structure, history, inhabitants and processes of change in its features. An important part of geology is the study of how Earth’s materials, structures, processes and organisms have changed over time. …
