How primordial oceans are formed, simply, thanks

The ocean** expands on the seafloor. There is more and more water vapor in the primordial atmosphere, and global precipitation intensifies. With the separation of continents, the seafloor magma upwells, gradually forming a sea basin landform, and the water accumulates to form the ocean.

The internal and external geology of the earth.

The formation of the oceans began at the beginning of the formation of the earth.

About 4.6 billion years ago, a part of the dust in the universe accumulated together to form the Earth, which was just formed at a very high temperature and full of erupting volcanoes. Volcanoes in addition to spewing magma.

In addition, a large amount of water vapor is emitted.

and other gases.

Later, the water vapor on the earth accumulated, and they became clouds when they were cold in the air. As the ground cools slowly, small droplets of water in the clouds turn into rain and fall. The large amount of rainwater that falls to the ground and finally collects in low-lying places, forming a primeval ocean.

The pristine ocean water is not salty, but acidic and hypoxic. The primordial seawater evaporated and fell, dissolving the salt of the land and the rocks on the seabed, and converging over hundreds of millions of years to form the ocean that is now formed.

1. The reason for the formation of the ocean is: a layer of crust located on the surface of the earth, in the process of cooling and condensation, is constantly impacted and squeezed by the violent movement of the earth's interior, so it becomes folded and uneven, and sometimes it is squeezed out, forming ** and volcanic eruptions, spewing out magma and hot gas.

2. For a long period of time, the water vapor in the sky and the atmosphere coexisted, and the sky was dense with dense clouds. As the earth's crust cools and the temperature of the atmosphere slowly decreases, the water vapor condenses with dust and ash and becomes water droplets. Due to uneven cooling, the air convection is violent, forming thunder and lightning winds, torrential rain and turbidity, and the rain is getting heavier and heavier, and it has been raining for hundreds of years.

The surging floods, through thousands of rivers, converge into a huge body of water, which is the primordial ocean.

3. In the primitive ocean, the sea water is not salty, but acidic and hypoxic. The water evaporates and repeatedly forms clouds and rain, which fall back to the ground, dissolving the salt from the rocks on land and the seabed and collecting them in the seawater. After hundreds of millions of years of accumulation and fusion, it has become a roughly uniform salty water.

01 Due to the thin crust of the earth and the continuous bombardment of the earth's surface by small celestial bodies, magma is constantly spewing out, so the earth is a sea of firewater accumulation. The magma is accompanied by a large amount of gas and dust, which rises into the air and forms clouds. Small droplets of water in the clouds turn into rain.

After a long period of rainfall, a large amount of rainwater gradually accumulated in the low-lying areas of the original crust, forming an ocean.

The vast interconnected waters of the Earth make up a unified marine world. Before scientists reach the bottom of the sea, it is all so mysterious and so fascinating. Humans with a spirit of exploration have marched to the ocean again and again to unveil the seabed.

The ocean is a general term for a vast and continuous body of saltwater on Earth. It has a total area of about 100 million square kilometers, which is about 71% of the Earth's surface area. If you look back at the earth from far away, you will feel that the earth is called"Water polo"Seems more appropriate.

The central main part of the ocean is called the ocean, and the peripheral part is called the sea. The sea and the ocean are connected to each other and together form a unified ocean of the world. So how did the ocean form in the first place?

The earth's crust is uplifted by the upwelling of internal materials and stretched to both sides under tension, resulting in local ruptures and the formation of a series of rifts and lakes. Later, the continental crust was eventually pulled off, and magma swelled up along the cracks, condensing into the continental crust, and a new ocean was born.

So where does the sea water come from? Water on Earth comes mostly from the atmosphere. At the beginning of the earth's existence, the internal matter differentiated at high temperatures to produce gases, forming a primitive atmosphere that included a large amount of water vapor.

Water vapor emitted by volcanoes is important for water on Earth**. When lava cools and crystallizes, it also releases large amounts of water. At the end of the day, both water and the atmosphere come from the Earth's interior.

These waters converge in the lower parts of the earth's crust to form lakes and oceans.
