Cork is the outer layer of bark from cork oak trees, primarily found in the Mediterranean region. It is harvested for various applications due to its unique properties: it is lightweight, buoyant, elastic, and fire-resistant. Cork is most commonly used for making bottle stoppers, but it is also used in bulletin boards, flooring, insulation, and even fashion items. The harvesting process is sustainable, as the bark regenerates, allowing the same tree to be harvested multiple times over its lifespan. Cork’s environmental benefits and versatility make it a valuable natural resource. It is unrelated to terms like hemisphere, distant, or tight.
