An account to igneous rocks




Granite: Continental crust is mainly formed of this Ba rock. It is composed of quartz, feldspar, mica and ro homblende and the colour of this rock varies from white, grey to pink. This is an impermeable rock. Granite is m very much resistant to erosion as it is heavy and very hard. Granite is coarse granied as the magma is cooled and solidified very slowly in the earths interior (diameter >3 mm). Landforms developed on the regions of granite rock are generally rounded and domal.




Basalt: Ocenic crust is mainly formed of this igneous and rock. This highly erosion resistant, hard, heavy rock white, may be grey to black in colour. Chief constituent ite is minerals of basalt are feldspar, olivine and pyroxene. very This rock is highly permeable as there are many joints -oled and cracks present in this rock. As magma cools and meter solidifies rapidly basalt is fine granied (diameter is < s of 1mm). Flat topped landforms are formd in regions composed of basalt rock.

A few words on three sedimentary rock: limestone, sandstone,shale by research studys

What is limestone ? Limestone : It is a calcareous sedimentary rock. Limestone or Calcium Carbonate is generally not soluble in water. But it gets readily dissolved in rainwater or acid solutions when it is transformed to Calcium Bicarbonate, which is not resistant to erosion and highly permeable. Surface water sinks underground through holes on the surface of the earth carved by solution actions of rainwater in Limestone regions. Limestone may be white, grey, green or blackish in colour. It is used as a raw material in making cement and in the iron and steel industry.  What is sandstone? Sandstone : It is a sedimentary rock rich in sand. It is resistant to erosion in spite of being highly porous and permeable. Architects use it in making epitaphs and monuments. It is yellow, orange, red, pink, white or grey in colour. Soil in regions dominated by Sandstone is saline and infertile. Many architectural wonders in India, like the Red Fort, the temples in Udaygiri-Khandagiri and K

What Is Classfication of waste (1) Solid waste, (2) Liquid waste, (3) Gaseous waste, (4) Toxic waste, (5) Non-Toxic waste:-

Classfication of waste: Depending upon the physical states, there are five types of wastes (1) Solid waste, (2) Liquid waste, (3) Gaseous waste, (4) Toxic waste, (5) Non-Toxic waste:-  (1) Solid waste: It is the solid portions of the discarded materials. It includes mainly domestic or household wastes like,kitchen waste with leftover cooked food, plastic, empty bottles, cans, broken glasses, discarded tyres,tubes, building rubbish, fly ash, carbon dust including various industrial wastes. (2) Liquid waste: Fluids as waste water, fats, oils or grease (FOG), used oil, excess manure,       hazardous household liquids, sewage effluents etc., are categorized as liquid wastes. (3) Gaseous waste: It includes uncontained airborne emissions and effluents, that may consist of particulate matter,dust, fumes, gas, mist, smoke, vapour or any combination. Examples of gaseous waste are particulate dust, gas flaring, lime dust, cigarette fumes, asbestos dust, waste gases and acid fumes.  (4) Toxic wa

what is concept of waste? waste management by research studys

  concept of waste   what is concept of waste ? waste is an undesired or unwanted substance which is of no use .It is a substancewhich is discarded after primary use or it is worthess, or defective term waste is often subjective because wate to one person is not necessarily a waste to another. waste  is also referred to as rubbish, trash or garbage which is the useless or worthless material stuff to be trown away. an idea for generation of local waste or waste from your locality would be useful for your general awareness. local wastes include mainly municipal waste generated by :-
