- Hadean (Wikipedia)
The Hadean (IPA: /heɪˈdiːən, ˈheɪdiən/ hay-DEE-ən, HAY-dee-ən) is the first and oldest of the four known geologic eons of Earth’s history. The Hadean eon started with the planet’s formation about 4.54 Bya, now defined as (4567.30 ± 0.16) Mya set by the age of the oldest solid material in the Solar System found in some meteorites about 4.567 billion years old. The proposed interplanetary collision that created the Moon occurred early in this eon, and the Late Heavy Bombardment is hypothesized to have occurred at the end of the eon. The Hadean ended 4.031 billion years ago, and was succeeded by the Archean eon.
- Cytisus scoparius has been introduced into several other countries and continents, outside of its native range, and is commonly classified as a noxious invasive species in western North America, mainly in British Columbia (including on Vancouver Island), California, Oregon, Washington (west of the Cascades), the Sierra Nevada range, fragmented areas of North America’s eastern seaboard, as well as Australia (where it is a declared weed), New Zealand, and in India.
