As per the s World Commission on Environment and Development in its report Our Common Future,  Sustainable development is defined as the development that meets the needs of the present without compromising the ability of future generations to meet their own needs".

We have to first see what is longitude of both city then take difference of both and this difference is 30 degree. now we know 1degree = 4 minute Therefore 30 degree = 120 minute i.e 2 hours. So answer is 2 hrs

Coromonda; Coast of Tamil Nadu receives monsoon twice in a year due to the effect of monsoon branch of the Arabian Sea (after summer)  and the Bay of Bengal (during winter).  

The first definition came from Allen (1980), who defined sustainable development as a "development that is likely to achieve lasting satisfaction of human needs and improvement of the quality of human life."

Most systematic definition came from Robert Repetto (1986), who defined sustainable develop-ment as a development strategy that tnanges all assets, natural resources and human resources, as well as financial and physical assets for increasing long term wealth and well being. Sustainable development as a goal rejects policies and practices that support current living standard by depleting the Productive base, including the natural resources.

Sustainable development contains two key concepts :

a) Needs, especially the needs of the poor people in the world, to which overriding priority is essential and

b) Limitations created by technology and social organisation regarding the capacity of the environment to satisfy both present and future needs.

The object revolves around the planet are called satellite. Natural satellite is made by Nature at the time of earth birth. It is the made up of rocks ,dust, gaseous. Their lifetime is too long. It not completely work on man made principles, it works on Nature principles.Eg, Moon. Artificial satellite made by human for their profit. It made up of elements which are know to human. It lifetime is small. It works on principles which are known to human. Eg., INSAT

Coromandel Coast

Life's supporting gases are those gases with support life on Earth, There are multiple gases in the atmosphere some of them are required for the maintenance of life the most important gas is oxygen because it supports the most of the living species of the planet. They get infused with the oxygen carrier cells for example, RBC in human for making the cell structurally and functionally viable. One more gas plays a major role in supporting life is Carbon dioxide because it is required in photosynthesis which ultimately makes food for the living species and maintains an equilibrium between them.

Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. Faults are planes of detachment resulting when rocks on either side of the displacement slip past one another.   Rocks that were originally deposited in horizontal layers can subsequently deform by tectonic forces into folds and faults. Folds constitute the twists and bends in rocks. Faults are planes of detachment resulting when rocks on either side of the displacement slip past one another.
