these waves may never really break when the waves approach the edge of the sea.

 Some waves can be said to "break". A broken wave is one of the waves whose base cannot reach its peak. The waves can break when running in shallow water, or when two waves conflict and combine strength. Affected by the size of the steepness and the waves are too large so that if the waves are broken it cannot be avoided.  Three main types of broken waves are known by surfers and surf rescuers. Different characteristics make the waves too or less suitable for surfing, and each has a different risk of danger.  1. Rolling: this is the safest wave for surfing. This wave can be found in most areas with a relatively flat coastline. This type of wave is the most common type of shorebreak. 2. Dumping: the waves break suddenly and can "throw" the surfer even pushing them down strongly. This is a wave for experienced surfers. Strong offshore wind and long waves can cause dumper. Waves like this are often found on the beach that have such as coral reefs or piles of sand.  3. Big waves: these waves may never really break when the waves approach the edge of the sea and the water below is very deep. These waves usually form on steep coastlines. This wave can drop the surfer and can drag the surfer back into the deeper sea.
