Albedo in urban and rural temperature saddle horsesAlbedo can be defined as the ratio of the amount of luminousness that a ceratin form supposes and the amount that it absorbs (Encarta , 2008 For standard , a body that rates an reflective power of 0 .3 can be construed to reflect back 30 percent of the light that falls on it , while absorbing the other 70 percent of the light (Encarta , 2008 . The term albedo is derived from the Latin term albus , or exclusively white (Dagmar Budikova , 2008 . When the object hit with the sun reflects back most(prenominal) of the temperateness , it is said to accept a extravagantly albedo ratio (National Science Foundation , 2006 . If the surface that is it by the sunlight abosrbs or takes in most of the light , it is said to have a humbled albedo (Science 2006Urban settings usually have low albedo since most of the light is absorbed by the alterations make by man of the natural landscape (Christopher lesser . In rural settings , the presence of abundant ve come ination ( baseborn . The plant keep absorbs most of the sun s light to start the process of photosynthesis necessary for the propagation of plants (Small . This cannot be wholly said for the urban setting , as the plant cover in the urban field of battles is minor(ip) compared to the rural environment (SmallBut the presence of plant life in the urban setting does have an impact on the carry quality and the health of those living in the urban areas (Christopher Small Roberta Balstad miller . It is assumed therefore that a host of physiological characteristics determine the albedo of a certain body (Encarta , 2008 . The laze , for example , has a low albedo order because of its coarse terrain , taking in most of the sunlight that hit it (Encarta , 2008 .

genus Venus , on the other hand , reflects back a mellow degree of the sunlight that it take in , thus could be said to possess a high albedo rating (Encarta , 2008As stated earlier , the presence of plant life in an urban setting does affect the albedo rating of the area (Small Miller . In the New York City area , for example , there is a mix of low and albedo ratings (Small Miller . This is due to the presence of trees in the area that are contributing(prenominal) to the build-up of dust and ozone in the specific location (Small Miller . enquiry at the National Aeronautics and Space Administration (NASA ) imbed out the the asphalt used in smoothing out set lots and roads , and dark-colored shingles and concrete had a high absorption capacity of sunlight than the rural areas surrounding the urban areas (Krishna Ramanujan , 2007 . This would result in a higher temperature in the cities (Ramanujan , 2007ReferencesBudikova , D (2008 . Albedo .
