¿De Dónde Vino el Agua de la Tierra?

The video explores the mystery of Earth's water, which covers 70% of its surface. Despite the solar system's formation from a dust and gas cloud, the inner solar system was too hot for water to form with Earth. Comets, initially considered as water sources, were ruled out due to their heavy hydrogen content. Instead, coal chondrites, a type of meteorite, are identified as the likely source of Earth's water, as they contain water with similar heavy hydrogen levels to terrestrial water.

What type of meteorite is suggested to be the most likely source of water on Earth?

How did the water that turned Earth into a blue marble arrive?
