properties of earth materials

A mechanical wave is a periodic disturbance, which requires a material medium (solid, liquid or gas) for its propagation. These waves are also known as elastic waves because their propagation depends upon the elastic properties of the medium through which they pass. Examples for..

The ultimate source of magnetism is the magnetic dipole moment, associated with an atom due to orbital motion and intrinsic spin. This suggests that all substances possess magnetic property as energy material consists of atoms having electrons revolving around the nucleus. Let u..

.7 million atmospheres (3.7 x 10 6 atm). It is because of this extremely high pressure that the iron in inner core can remain in the solid state despite the very high temperature. Since the pressure is comparatively lower in the outer core, the iron remains in the molten form in the outer part of t..

Metallurgy is a domain of Material Science and Material Engineering. It is a study of the physical and chemical behavior of metallic elements and their mixtures, called alloys. Metallurgists study the microscopic mechanisms that cause a metal or alloy to behave in the way that i..

Metallurgy - Metallurgy is a domain of Material Science and Material Engineering. It is a study of the physical and chemical behavior of metallic elements and their mixtures, called alloys. Metallurgists study the microscopic mechanisms that cause a metal or alloy to behave in t..

Introduction - In the chapter on current electricity, we had learnt about the flow of charges, conditions to produce the flow and how different materials respond to an external electric field. We had seen how materials are classified as conductors and insulators. In this chapter..

Fig 4.1 Acceleration produced in the stone is due to the large force of attraction exerted by the Earth It is clear from the above example that it is this force of attraction that holds our complex universe together, keeps the moon revolving around the Earth and holds all the pl..

Natural materials found inside the earth containing metals in their combined states (as a single compound or as a mixture of compounds) mixed with non metallic impurities of Earth and rock (called gangue), are termed minerals. These metals do not occur in the native f..

Soil can be defined as the uppermost crust of earth mixed with organic material and in which animals and microorganisms live, and plants grow. The word soil is derived from a Latin word solum meaning ground. It is a stratified mixture of inorganic and organic materials..
