Which items are used to show elevation relief and slope on a topographic map?
Natural EnvironmentsWhat are contour lines? Contour lines connect a series of points of equal elevation and are used to illustrate relief on a map. They show the height of ground above mean sea level (MSL) either in metres or feet, and can be drawn at any desired interval. Which items are used to show elevation relief
Which geographer developed the theory of environmental perception?
Natural EnvironmentsWhat is environmental perception? Environmental perception has commonly been defined as awareness of, or feelings about, the environment, and as the act of apprehending the environment by the senses. Who came up with the theory of environmental determinism? Friedrich Rätzel Environmental determinism rose to its most prominent stage in modern geography beginning in the late
Does grain size number increase or decrease with decreasing grain size?
Natural EnvironmentsDuring this process grain size or shape of material should not change. ASTM grain size number(n) is related with the number of grains that you can count in 100X magnification (N) by the relation, N=2(n–1). So ASTM grain size number increases with decreasing grain size. Why does grain size number increase with decreasing grain size?
What is the symbol of roughness?
Natural EnvironmentsRoughness (referred to as tool marks) generally results from a production process or material condition. Roughness is measured in a transversal direction to the main grooves. – The mean arithmetical value “Ra” in μm is assumed for roughness measurements. What is the unit for roughness? microns Average roughness is typically measured in either microns (µm)
What does silt feel like?
Natural EnvironmentsSilt feels like flour. It forms into a ball that easily breaks apart. If you squeeze it between your thumb and fingers, it will not form ribbons. Clay feels sticky when wet. What is the texture of a silt? Both silt and clay soils have a very smooth texture. Does silt feel rough? Sand are
What is the definition of geospatial technology?
Natural EnvironmentsWhat is the meaning of geospatial technology? Geospatial Technology is an emerging field of study that includes Geographic Information System (GIS), Remote Sensing (RS) and Global Positioning System (GPS). Geospatial technology enables us to acquire data that is referenced to the earth and use it for analysis, modeling, simulations and visualization. What is an example
