The length of coastal plain of Pakistan is about 700 kilometers which starts from the border of Sindh with an Indian and ends at Pakistan and Iran in the West. The coastal areas of Pakistan are very important due to its geographical situation. Also the possibility of mineral oil in the sea has increased the importance of coastal regions. That is why the government is giving more importance to the progress of these areas.
The area which consists of ridges trough basin plains and dessected plains is known as Plateau.
