A freaky natural phenomenon was witnessed over the weekend at Yamba Beach, New South Wales, Australia… with foam swallowing an entire beach and nearby buildings.
Scientists explain that the foam is created by impurities in the ocean, such as salts, chemicals, dead plants, decomposed fish and excretions from seaweed. All are churned up together by powerful currents which cause the water to form bubbles.
These bubbles stick to each other as they are carried below the surface by the current towards the shore. As a wave starts to form on the surface, the motion of the water causes the bubbles to swirl upwards and, massed together, they become foam.
