Oceans began to form much earlier in Earth's history, not just near the end of any geologic period. The formation of oceans is believed to have started over 4 billion years ago, shortly after the planet itself cooled enough for water to exist in liquid form. This early ocean formation occurred during the Hadean and Archean eons, laying the foundation for the development of life and the evolution of the Earth's atmosphere.

How many years is the concept of geologic time?
The Earth has existed in roughly its present form for about 4.5x109 years.
What is the main source of energy for convection in the atmosphere and the oceans?
The Sun is the main source of energy for convection in the atmosphere and the oceans. The Sun, heat radiated form the Sun is the main source of energy driving convection in the atmosphere and oceans. There is also a small input form geothermal energy.
Where does ocean get salt?
- salt is dissolved from the earth (also as ions Na+ and Cl-) and transported in oceans by rivers - chlorine from volcanic activity in oceans and sodium from the earth form NaCl
How did the Sierra Nevada form?
The earliest granite was formed in the Triassic period. Toward the end of that period, and into the Jurassic period, the Nevadan orogeny occurred. Later, during the Cretaceous period, the subduction of the ancient Farallon Plate caused magma to rise, creating the Sierra Nevada batholith. A mere 32 to 50 million years later, this 'proto-range' became eroded down to low rolling mountains, just a few thousand feet high. Then, about twenty million years ago, extensive volcanismoccurred. About four million years ago, the range as we know it began to form when a large block of the Earth's crust began to tilt toward the west. Deep canyons began to be cut on both sides of the range by the erosive action of rivers. The overall climate of the Earth began to cool, and ice ages began, around 2.5 million years ago. Glaciers cut away the classic U-shaped canyons throughout the range. River and glacier erosion subsequently exposed the remnant of metamorphic rock that remains atop some of the peaks today. Uplift continues, causing large earthquakes.For more information, see the Related Link listed below:

What is a Paleogene?
The Paleogene was a geologic time period, the first of two periods of the Cenozoic era. It began 65.5 million years ago following the end of the Cretaceous Period, the last period of the Mesozoic Era. It ended 23 million years ago and was followed by the Neogene, the current period. During this time, Earth recovered from the mass exinction event that wiped out the dinosaurs and mammals became the dominant land animals. India collided with mainland Asia, forming the Himalayas, and ice sheets began to form in Antarctica.
When did earths atmosphere oceans and continents begin to form?
Earth's atmosphere, oceans, and continents began to form around 4.6 billion years ago during the planet's early stages of formation. The atmosphere likely evolved from gases released during volcanic activity, while the oceans formed from water vapor that condensed as the Earth cooled. The continents began to form through the process of plate tectonics, with land masses emerging and colliding over millions of years.
What is the possessive form of oceans?
The possessive form of the plural noun oceans is oceans'. Example: The oceans' currents north of the equator are a clockwise rotation.
What do the current landforms of the Cambrian period look like?
In the Cambrian period, the world's oceans were beginning to form because the glaciers were melting. Most of the world's land was in the Southern Hemisphere.
Earth and atmosphere oceans and continents began to form during the first several hundred million years of?
Earth's formation began around 4.6 billion years ago, with the planet gradually cooling and solidifying. During the first several hundred million years, volcanic activity released gases, forming the early atmosphere, while water vapor condensed to create oceans. Simultaneously, continental crust began to form through processes like plate tectonics and volcanic activity, leading to the development of distinct landmasses. This period set the stage for the diverse environments that would eventually support life.
Where can you find oceans?
The oceans form most of the surface of the World.
What is the plural form of ocean?
The plural of ocean is oceans.
In which geologic period did pangaea form?
Pangaea, the supercontinent, formed during the late Paleozoic era, specifically during the Permian period, around 335 million years ago. The process of Pangaea's formation is known as the "assembly" phase of the supercontinent cycle.
