The Malabar coast, in historical context, refers to India’s south-western coast, which lies on the narrow coastal plane of Karnataka and Kerala states between the Western Ghats range and the Arabian Sea. The coast runs from south of Goa to Kanyakumari on the southern tip. The coastal boundry line is mutilated, so natural ports have developed in this region. Due to strong sea breeze, sea sand gathers and deposits here, from which minerals like monazite etc. are obtained. Several lagoons are also found on this coast. The Cochin port is situated on one such lagoon. Besides this, Mangalore, Alleppey, Kozhicode, Thiruvananthapurm, etc. ports are also situated on this coast.
