Geotechnical Engineering correct answers Broader term for Soil Mechanics Soil Mechanics correct answers one of the disciplines of civil engineering that involves the study of soil, its behavior and application as an engineering material. Soil Mechanics correct answers is the application of laws of mechanics and hydraulics to engineering problems dealing with sediments and other unconsolidated accumulations of solid particles produced by the mechanical and chemical disintegration of rocks regardless of whether or not they contain an admixture of organic constituent. Karl Terzaghi correct answers Father of Soil Mechanics Soil is the substance existing on the earth's surface, which grows and develops plant life. correct answers Meaning of Soil according to pedologist Soil is the material in the relative thin surface zone within which roots occur, and all the rest of the crust is grouped under the term ROCK irrespective of its hardness. correct answers Meaning of soil according to geologist Soil is the un-aggregated or un-cemented deposits of mineral and/or organic particles or fragments covering large portion of the earth's crust. correct answers Meaning of soil according to an engineer Soil Mechanics is one of the disciplines of Civil Engineering that involves the study of soil, its behavior and application as an engineering material while Geotechnical engineering is the subdiscipline of civil engineering that involves natural materials found close to the surface of the earth. It includes the application of the principles of soil mechanics and rock mechanics to the design of foundations, retaining structures, and earth structures. correct answers Distinguish between Geotechnical Engineering and Soil Mechanics Soil is the un-aggregated or un-cemented deposits of mineral and/or organic particles or fragments covering large portion of the earth's crust. correct answers State in your own words the meaning of SOIL Weathering correct answers breaks down and alters rocks and minerals at or near the earth's surface and is divided into physical weathering and chemical weathering Chemical weathering correct answers is the decomposition of materials by a series of chemical reactions that result in the rust on cars or the corrosion or staining of building facades Hydrolysis correct answers is a decomposition process in which water is one of the reacting agents.
