Surveying is the method of determining the distance and elevation using instruments and geometry.
<u>Explanation:</u>
Surveying is methodology used to determine the area of the land in real estate sector and infrastructureprojects. It is the coalescence of mathematical calculation and scientific concepts. It not only measure the area size, which is also used to measure the elevation like height of Himalayan mountain, dam strength and so on. Survey of India is established in 1767, it is the oldest department in India in engineering field.
the study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources and political and economic activitie
On a geologic map, if the contacts between sedimentary rock units form a bull’s-eye pattern of concentric circles, with the oldest unit in the center, the underlying structure is a syncline.
The atmosphere on earth is mostly a result of the interaction of solar winds and earth gravitational pull. The planet takes incoming shortwave insolation that heats the surface from above and charges the surface from below.
At night it gives this absorbed energy as a black body out in the space when it completes a cycle of <u>12 hours and this in long waveforms of energy with IR radiation that is quite less as compared to that of suns.</u>
Like a black body, the earth radiated this heat bk as it cannot afford to keep much as is to balance the energy flow within and out of the earth system.
