properties of earth materials

They are not deflected by electric and magnetic fields. They affect photographic plates. The ionising power is very low compared to alpha-particles and beta-particles. They are electromagnetic waves like X-rays and light rays. The wavelength of these rays are shorter than that of X-rays...

The relative abundance of noble gases along with their electronic configurations is given in the table. Electronic configurations of noble gases Element Symbol Atomic No. Electronic Configuration Abundance In Earth’s Crust (in ppm) Helium He 2 1s 2 ..

Travel in Straight LinesWhen an opaque object like a metal cross is placed in the path of cathode rays in a discharge tube, a shadow of the metal cross is formed at the end opposite to the cathode. The placement of the shadow proved that these rays follow a straight line. Produce Mechanical..

Earth is an abundant source of material. Man has intensively studied the properties of these materials extensively and found new methods of using them. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are al..

Earth is an abundant source of materials. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for some purpose or the other. Gaseous materials like Oxygen, Nitrogen and Carbon dioxide are found in the at..

The p-block contains several elements of great social and economic importance as well as chemical interest. Examples include the use of aluminium as a structural material, the importance of silicon and germanium as semiconductors, and the use of sulphur, phosphorus and nitrogen in fertili..

It should always be remembered that whenever you have to charge a body, it must be insulated from the earth. It means that the body should be supported on a stand which is made of an insulating material which does not allow charges to pass into the earth..

These rocks are formed by direct cooling of the molten material of the earth resulting in crystallization of minerals. Such rocks form the largest portion of the earth's crust e.g., Quartz, Magnetite, Mica, Feldspar and Granit..

Soil can be defined as the uppermost crust of earth mixed with organic material and in which animals and microorganisms live, and plants gro..
