Based on Wikipedia’s, Driftwood is wood that has been washed onto a shore or beach of a sea, lake, or river by the action of winds, tides or waves. It is a form of marine debris or tide wrack.
Meanwhile, some wood experts say that Driftwood is dead old wood that has been in the water for an extended period of time. This wood loses all its skin, it is often bleached by the sun, and is usually has lighter color than ordinary wood. You can find it on the beach, in a lake, or even in a river. This type of wood can be placed in an aquarium, used as decoration and to reduce water pH. This can also be used for crafts and such.
There are many sources of origin of driftwood. Large branches are dropped by storms, for example, and sometimes entire trees fall and they are carried by currents to open water areas. It can also come from damaged ships or due to other human structures, sometimes taking the ready-made wood. During stormy weather, strong winds and waves can cause a large accumulation of wood on the beach; some of them will drift into the sea if they are not collected.
There will be many things happen when wood floats, such as being exposed to bacteria, being eaten away by animals, being exposed to direct sunlight, and other things. For this reason, when on land, driftwood is often very light after drying, and it can be a great source of fuser.
Ecologically, driftwood is an important component of coastal ecosystems. From the framework of the whole tree to a small piece of driftwood, each piece of driftwood provides benefits to the coastal ecosystem. Besides being useful for the beach, this type of wood is often used by artists for various types of crafts. Some artists use wood that was previously floating as it is, while others may carve or cut it, using it to make bases for statues, picture frames, and other crafts. The wood can also be used to make furniture, sticks, and fences.
