Black sand beaches can be formed by the Earth's weather patterns causing lava to erode into the sandy beaches. The tides help break up the lava that rests on the shallow ocean floor -- turning it into a fine sandy material -- and then will redeposit the sand on the beach.hough black sand beaches are a rare occurrence throughout the world, there are several regions where they are common. Islands that have black sand beaches include Iceland, Hawaii, Indonesia and Polynesia.
Sand dunes only form where the rate of beach deposition is greater than erosion (positive sediment budget). Sand Dunes on Flamborough Head. When the dried sand reaches the top of the beach it can be trapped by debris such as driftwood, dead seaweed or rocks and pebbles.idge and runnel systems are formed due to the interaction of tides, currents, sediments and the beach topography. They only form on beaches with a shallow gradient. They form as a simple drainage route for tides. Water flows in and out via the runnel.
