Q. Which is a black sand beach in Karnataka?
Answer: Tilmati Beach, Karwar
Notes: Tilmati Beach near Karwar is one of India's few black sand beaches. Its black sand is formed by wave erosion of basaltic rocks creating a dark, mineral-rich shoreline. The beach is located close to the Karnataka-Goa border and its name is derived from local Konkani words for sesame and soil. It is accessible by a trek from Majali Village and has historical significance as a former trade point between British and Portuguese territories.
