Caves, blowhole, geo sequence

Question 1

Caves, blowhole, geo sequence step 1

Answer 1

Marine erosion processes create sea caves along a line of weakness

Question 2

Caves, blowhole, geo sequence step 2

Answer 2

Waves force air and water into the cave, creating a shaft upwards to the surface and forming a blowhole where water gushes out in certain tide and wave conditions

Question 3

Caves, blowhole, geo sequence step 3

Answer 3

Continued erosion cause the extended cave root to collapse leaving a long narrow inlet - (A geo). Geos can form along a line of weakness where erosion processes have a greater impact.
