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, which protect the coastline from storm winds and waves, are formed when waves carry sand to the beach, where the wind picks it up and blows it inland. Gradually, the sand piles up and plants such as sea oats begin to grow in it. The sea oats slowly cover the entire dune and protect it from erosion.
