Deep-sea wood is the term for wood which sinks to the ocean floor. These wood-falls develop deep sea ecosystems. Deep-sea wood supports unique forms of deep sea community life including chemo-synthetic bacteria. Sources of carbon for these deep sea ecosystems are not limited to sunken wood, but also include kelp and the remains of whales. Much ...
Lignum vitae is hard and durable, and is also the densest wood traded (average dried density: ~79 lb/ft 3 or ~1,260 kg/m 3); [4] it will easily sink in water. On the Janka scale of hardness, which measures hardness of woods, lignum vitae ranks highest of the trade woods, with a Janka hardness of 4,390 lbf (compared with Olneya at 3,260 lbf, [5] African blackwood at 2,940 lbf, hickory at 1,820 ...
Rafting to Vancouver, British Columbia Canada (August 2006). Raftsmen in Northern Finland in the 1930s Timber rafting on the Willamette River (May 1973).. Timber rafting is a method of transporting felled tree trunks by tying them together to make rafts, which are then drifted or pulled downriver, or across a lake or other body of water.
A few Diospyros species, such as macassar and mun ebony, are dense enough to sink in water. Ebony is finely textured and has a mirror finish when polished, making it valuable as an ornamental wood. [1] It is often cited as one of the most expensive woods in the world.
After this occurs and once the tubes are securely in place, a hookah compressor and a low-pressure hose re-inflates them so that they form a tight grip around the floating logs. This process gives the logs more buoyancy and gives loggers easier access points to harvest them. As many tubes that are needed are used to float the logs. [4]
Jan. 23—Q: We're always wondering, why does wood burn in squares? You sit around any kind of a wood fire, you notice the wood always burns in squares. We're always wondering why.
Earthquakes are common on the West Coast, with multiple plate boundaries like the San Andreas fault making geologic activity more likely. They are rarer on the East Coast, but they do happen ...
The Guinness Book of World Records lists this tree as the world's heaviest wood, with a specific gravity of 1.49, similar to that of anthracite or dry earth. [8] It is known for its tendency to sink in water, unlike other wood materials. It is also one of the world's hardest woods according to the Janka hardness test. The timber has a good ...
