Nature continues to increase its wide array of wonders by showing us a black iceberg, something most people wouldn’t even think could possibly exist.
According to the Canadian Encyclopedia, a black iceberg isn’t rare but it is also rarely seen.
Apparently, a lot of icebergs have either a black, green or brown shade on their bottom section that usually lies below the water. The ”black iceberg” is seen when water and wind pressure forces one of these icebergs to simply roll over.
The encyclopedia explains:
“These (colored) icebergs have usually rolled over, exposing basal ice, or have emerged from below water level. The various colorations are caused by differences in density, air-bubble content and impurities. For example, black ice is of high density and bubble free; dark layers indicate the presence of rock materials derived from the base of the parent glacier.
Occasionally, rocks may be found on the original upper surface of the iceberg. As the iceberg melts, these materials precipitate into marine or lake sediments.”
