2. A coastal flood is associated with cyclones, high tides, and tsunamis.

• A. Statement 1 is correct and statement 2 is incorrect.
• B. Both the statements are incorrect.
• C. Both the statements are correct.
• D. Statement 1 is incorrect and statement 2 is correct.

Answer 1

The correct option is C Both the statements are correct.

Snow and rainfall are significant components of the water cycle. During warmer weather, temperatures rise above freezing point. This causes the snow to melt, and this water current reaches streams, rivers and drainage systems, nearby. Thus, snow melting causes water to rise out of the banks, swamping any adjacent land.

Changing sea levels are affecting human activities in coastal areas. Rising sea levels inundate low-lying wetlands and dry land, erodes shorelines, and contributes to coastal flooding. Coastal flooding occurs due to seasonal high tides, cyclones, and tsunamis.
