Over a few hundred million years, the planet began to cool and the oceans initially formed. kwilliams28_15 https://padlet.com/kwilliams28_15/ste0houyse8kj5rt/wish/2982010409 2024-05-06 17:45:24 UTC https://padlet.com/kwilliams28_15/ste0houyse8kj5rt/wish/2982010409 "Collisions between these cosmic bodies [asteriods] likely deposited much of the water on Earth's surface. Our planet lies in what is known as the Goldilocks zone, a region surrounding a star that is close enough for liquid water to exist on a planet's surface, with water neither freezing nor evaporating. Many scientists think that being in this zone, and the presence of liquid water, plays a key role in the existence of life." kwilliams28_15 https://padlet.com/kwilliams28_15/ste0houyse8kj5rt/wish/2982026007 2024-05-06 17:58:20 UTC https://padlet.com/kwilliams28_15/ste0houyse8kj5rt/wish/2982026007 The Sun and the planets formed together around 4.6 billion years ago. It formed from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion likely started the formation of the solar system. kwilliams28_15 https://padlet.com/kwilliams28_15/ste0houyse8kj5rt/wish/2982034131 https://www.amnh.org/exhibitions/permanent/the-universe/planets/formation-of-our-solar-system

Some synonyms include the Eozoic, the Cryptozoic, etc.
