The water for Earth’s oceans originally came from ____.
Water vapor from valcanos
Water vapor from volcanoes
To find out where the water for Earth's oceans originally came from, we need to delve into theories on the origin of water on our planet. There are several hypotheses that scientists have proposed.
One prominent theory is that the water on Earth came from comets. Comets are celestial bodies composed of ice and other volatile compounds, and they have been present in the early solar system. As these icy bodies collided with the young Earth, they may have released water, contributing to the formation of Earth's oceans.
Another theory suggests that water was already present in the materials that formed our planet. During the early stages of Earth's formation, when gravity caused particles to come together, gases and water vapor might have been trapped within the planet's core. It is believed that over time, as the Earth's crust cooled down and solidified, water vapor was released and condensed into liquid form.
Additionally, volcanic activity played a role in releasing water into our atmosphere. Volcanoes release water vapor, carbon dioxide, and other gases during eruptions. This released water vapor could have condensed and accumulated over time to form the Earth's oceans.
It's important to note that these theories are still being researched, and the exact origin of Earth's water is still not fully understood. However, ongoing studies and missions, such as the analysis of comets and meteorites, continue to provide valuable insights into this intriguing question.
