There are two schools of thought as to how Earth's oceans were formed. The first says that volcanic gases emitted steam as the crust cooled and overtime oceans were formed. The second states that an ateriod laden with ice crashed into Earth giving it its oceans. The resulting dust and debris that ricocheted into space after the impact was drawn back into earth'sgravitaional field and condensed into the moon. This makes much more sense because when when you compare Mars to Earth we have oceans and a different type of moon even though we're closely sized planets.
What else can I help you with?
Did earth first oceans form?
It was about 4 billion years ago, that the Earths oceans formed
What is the source of most water that evaporates from earth surface?
The main source is formed by sea and oceans.
What happened to water vapor when earth formed and cooled?
When the Earth formed and cooled, water vapor condensed into liquid water and fell as rain, filling the forming oceans. This process, known as the "water cycle," involved continuous evaporation and precipitation of water, contributing to the formation of the Earth's oceans and atmosphere.
How do scientists think that Earth's oceans formed?
Scientists believe that Earth's oceans formed about 4 billion years ago through a process called "outgassing," where water vapor and other gases were released from the Earth's interior through volcanic activity. As the Earth cooled, the water vapor condensed and fell as rain, filling the low-lying areas to create the oceans.
The oceans were formed when precipitation filled low areas on earth called what?
I think its Basin
Did oceans form as soon as the earth formed?
No, when the Earth first formed it was molten, it had to cool before liquid water could collect in its surface. There is also a thought that Earth's water may not have formed form the initial materials making up the Earth but been delivered to the Earth by comet or asteroids impacting the Earth later.
How long did it rain to form the oceans?
The oceans formed over millions of years as rainwater accumulated in low-lying areas on Earth's surface.
What were the characteristics of Earth before the oceans formed?
Before the oceans formed, Earth was a hot and volatile planet with a thick atmosphere of mainly carbon dioxide and water vapor. The surface was mostly covered in molten rock due to intense volcanic activity. As Earth cooled over millions of years, water vapor condensed to form the oceans.
Why are the continents older than the oceans?
because they formed first along with the layers inside the earth
According to scientific hypothesis how were earths oceans formed?
One scientific hypothesis suggests that Earth's oceans formed through the outgassing of water vapor from the planet's interior during volcanic activity. This water vapor eventually condensed and fell as rain, filling the low-lying areas on the Earth's surface and forming oceans.
How are mountains and oceans formed?
Mountains are formed by the movement of tectonic plates, where plates collide and push against each other, causing the Earth's crust to fold and uplift. Oceans are formed from depressions in the Earth's crust that fill with water over time, often due to the shifting of tectonic plates or volcanic activity.
When the earth cooled oceans formed as water vapor?
As the Earth cooled, water vapor in the atmosphere condensed into liquid water, forming oceans. The process of water vapor condensing also released heat, contributing to the cooling of the Earth's surface. This eventually led to the formation of the oceans we have today.
