Mechanical properties like strength, stiffness (Rigidity), ductility, malleability and brittleness have to be carefully studied to select a material for a particular job. The metallic parts of machines should not be subjected to stress beyond the elastic limit otherwise they ..

Three quantities are needed to specify the magnetic field of the earth on its surface - the horizontal component, the magnetic declination, and the magnetic dip. Please refer to the text for precise definitions of declination and dip. Consider a material placed in an external ma..

The term 'natural resources' refers to all the natural things on our earth. It includes everything, that is naturally available and that is not creatable by any human activity. It specifically excludes the materials created by ma..

The word soil is derived from the Latin word solum meaning earthy material in which plants grow. The science which deals with the study of soil is called Soil Science, Pedology (pedos = earth) or edaphology (edaphos = soil..

There are 109 elements known at present. 92 elements occur in nature, while the rest are man-made. All materials on the Earth are made of these naturally occurring elements. These are classified into metals, non-metals, and metalloids. The occurrence and extraction of some..

Earth's crust is rich in inorganic materials. It includes ores, that are used on a large-scale to yield metals such as iron, aluminium, copper, tin, nickel, silver, gold, platinum et..
