Ppt Oceans Powerpoint Presentation Free Download Id 514229 Researchers think that the oceans formed as a result of a process known as “degassing.”. when the earth was first formed, its temperature was well above the boiling point for water. because of this, there was no liquid water on earth. instead, all water was in the form of a gas. a side note: this water was believed to be squeezed out of the. Learn how the ocean evolved from a waterless planet to a vital source of life and climate regulation. discover how tectonic plates, volcanoes, comets and climate change have shaped the ocean over billions of years.
Ppt Aquatic Biomes Powerpoint Presentation Id 528098 Ocean formation after earth began to form about 4.6 billion years ago, it gradually separated into layers of lighter and heavier rock. the lighter rock rose and formed earth’s crust. the heavier rock sank and formed earth’s core and mantle. the ocean’s water came from rocks inside the newly forming earth. "hence, the best model for the source of the oceans at the moment is a combination of water derived from comets and water that was caught up in the rocky body of the earth as it formed. this. The exact timing of the formation of the oceans is still debated among geologists, but most scientists believe that they formed around 4 billion years ago, shortly after the formation of the earth. the most widely accepted theory for the formation of the oceans is that they were created by volcanic activity that released water vapor into the. According to the most recent scientific studies, an ancient ocean likely covered the entire planet 150 million years after the formation of earth, about 4.4 billion years ago. scientists know this through the discovery of ancient zircon crystals that were dated around this time.

Creation and collection of water. when the earth was formed 4.6 billion years ago, it would never have been called the blue planet. there were no oceans, there was no oxygen in the atmosphere, and no life. but there were violent collisions, explosions, and eruptions. in fact, the earth in its earliest stage was molten. Learn how the oceans formed from volcanic activity, outgassing, and water delivery by comets or meteorites. explore the hydrological cycle and the salinity of the oceans.
