Soil - correct answer Uncemented aggregate of mineral grains and decayed organic matter with liquid and gas in the empty spaces between the solid particles. Soil Mechanics - correct answer Branch of science that studies the physical properties of soil and the behavior of soil masses Geotechnical Engineering - correct answer Subdiscipline of civil engineering that involves natural materials (soil and rock) found close to the surface of Earth. Geotechnical Engineering before 18th century - correct answer based on past experiences through a succession of experimentation Geotechnical Engineering pre-classical period - correct answer Studies of natural slopes of soils and their shear strength Studies of lateral earth pressures on retaining walls A model test of a retaining wall Geotechnical Engineering classical period - correct answer Position of sliding surface in soil behind retaining wall Permeability of sand filters (Henri Darcy) Overturning moment on a hinged retaining wall Stress distribution under load bearing areas Karl Terzaghi - correct answer Father of modern soil mechanics igneous rock - correct answer Rocks formed by the solidification of molten magma. Can be intrusive within the earth's crust or extrusive Bowen's reaction principle - correct answer Rate of cooling affecting the formation of different minerals Rhyolite - correct answer example of an extrusive igneous rock Granite - correct answer example of an intrusive igneous rock Weathering - correct answer The process of breaking down rocks into smaller pieces Types of Weathering - correct answer mechanical and chemical Mechanical weathering - correct answer Type of weathering that occurs due to temperature changes, erosion, and other contact related disintegration Chemical weathering - correct answer Type of weathering that occurs due to chemical reactions from one mineral to another Transported soil types - correct answer Glacial Colluvial Alluvial Aeolian Lacustrine Marine Residual Glacial soils - correct answer Transported by glaciers Colluvial soils - correct answer Transported by gravity Alluvial soil - correct answer Transported by running water Aeolian soil - correct answer Transported by wind Lacustrine soils - correct answer Transported by lakes Marine soils - correct answer Formed by deposition in the seas Residual soils - correct answer Soil that remain at their place of origin Sedimentary rock - correct answer Rock that consists of the deposits of gravel, sand, silt, and clay formed by weathering Detrital Sedimentary Rocks - correct answer Rock that was formed when the deposits are compacted and cemented by agents like iron oxide, calcite, dolomite, and quartz Cementation agents - correct answer iron oxide calcite dolomite quartz Chemical sedimentary rock - correct answer Rock that is formed when the deposits react chemically with other agents Metamorphism - correct answer The process of changing the composition and texture of rocks by heat and pressure without melting *Leading to new minerals formed *Mineral grains are sheared to give a foliated texture Specific Gravity - correct answer The unit weight of a given material divided by the unit weight of water
