using mineral nutrient solutions‚ in water‚ without soil. It is not a new invention‚ but its popularity is currently increasing drastically. People are now using this process of growing plants‚ flowers‚ and vegetables without soil in their homes‚ where previously it was mostly used just by professional gardeners. Because of the ’hydro’ in the name‚ it is a common misconception that the plants are being grown in water instead of soil. They are in fact grown in liquid‚ but it is a mineral nutrient

has provided the trigger to boost economy of the mining talukas. Certain natural factors like the presence of coastline‚ a very good natural harbour at Marmugao and a number of navigable perennial rivers have promoted the economic exploitation of mineral deposits. Transport of ores by barges is the cheapest option as compared to road and rail transport. Goa is a major iron ore exporting state and over 60% of Country’s iron ore export is from Goa. In terms of foreign exchange earnings it amounts to

classified as either physical or historical geology. Physical geology is the study of Earth materials‚ operating as minerals and rocks‚ as well as the processes operating within Earth and on its surface (Monroe‚ 2001). Geology influences the strength of the rocks‚ the ability to process the given deposit with existing processing techniques and stability of excavation made in the mineral deposit. This emphasizes the importance of geology to mining operations hence it should be properly studied to avoid

INTRODUCTION The aim of the study was to find out how does the sediment grain size and mineralogy distribution change across a beach profile. Mineral is a homogenous‚ naturally occurring solid inorganic substance with a definable chemical composition (Marshak‚ 2005). The impacts of the depositional environment‚ transport and climate on the morphology of minerals oceans are the focus of discussion during the

cooling sets up stresses in the rock that cause it to disintegrate. Occurs mostly in deserts where there is the greatest diurnal temperature range. Also occurs during bush fires. Wetting & Drying (Slaking) Rock is alternately wetted then dried. Minerals which make up clay rocks expand when wetted‚ then contract on drying-out. The stresses from repeated expansion and contraction cause the rock to disintegrate. This process commonly occurs on the intertidal zone of coasts. Exfoliation (Onion weathering/Spheroidal)
