This book is a comprehensive product on the geomorphology of sea coast. The book explains various landforms and geomorphic processes occur on a coastal scenario. The learning activities relentless enquiries, and critical thinking will help you to open the window of knowledge.
Coastal Scenario Coastal landforms are created by the erosional and depositional processes carried out by waves.
Let us take a look at some landforms along coastlines.
SEA CLIFFS
The steep hillocks facing the sea are called Sea Cliffs. These steep structures are formed by the crumbling of the sea-facing slopes due to wave erosion.
The Varkala Cliff, Thiruvananthapuram
Sea Cliffs
SEA STACKS
The strong blast of sea waves on the rocky coasts cause the wearing down of rocks. As a result of such abrasion by waves, isolated rock pillars are formed from coastal rocks. Such pillar rocks standing upright along the coastline are called Sea Stacks.
Sea Stacks of Thalasseri Beach, Kannur
How do these stacks withstand the strong wave erosion? --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
BEACHES
Beaches are formed s a result of the deposition by waves. Beaches are depositional landforms along the coastlines formed with sand, gravel, etc.
You might be aware of the tourism prospects of a few prominent beaches in Kerala
