   What is Magma?
 
Ans:- Due to enormous pressure and temp erature the substance of the earth's interior remain liquid, being mixed with gas and vapour is called magma. 
 
Short Ans:- molten rock material inthe earth 's interior is known as magma



                               
   What is lava?
 
Ans:- When hot molten magma of the earth's interior, comes out through the cracks and joints on the earth's surface, it is called lava As temperature rises a substance melts into liquid and increases in volume. On the other hand, when pressure increases, there happens to be a severe contraction in the same volume of mass. Both pressure and temperature are incredibly high in earth's interior. 

Short Ans:- when this magma comes out to the earth's surface, it is as lava.

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
