Coastal Erosion and Its Impacts

The video tutorial covers coastal erosion, its causes, and effects, particularly focusing on the impact of wind and waves. It highlights the increased erosion during the southwest monsoon, affecting regions like Kerala, Karnataka, and Goa. The tutorial also discusses prevention measures such as prohibiting sand mining, constructing retention walls, and growing mangrove forests to mitigate erosion.

• Both coasts are equally affected

• Neither coast is affected

• It is more severe on the east coast

What is a major consequence of coastal erosion?

• Increase in land area

• Submersion of land into the sea

• Formation of new beaches

• Rise in sea level

Which of the following is NOT a prevention measure for coastal erosion?
