Venus is the second planet of the solar system. Similar to earth in its size and material it is made of. It is closer to the earth such that it is the closest planet to earth. Still, Venus is a hellish planet to be habitable. It is called earth's twin.
Venus has more than 90% of carbon dioxide in its atmosphere. Its atmospheric pressure is 90 times that of Earth. Its surface has not cooled down although it was formed at the same time as the earth was formed.
Venus the hellish planet
It is well-known fact that the solar system was created 5 billion years ago. Earth started its formation 4.5 billion years ago and during the same time, Venus was formed. Earth took away a totally different journey and become the only habitable planet in the solar system. Venus instead of being made of the same material, same size, and composition has become a hellish planet. It is the most inhabitable Planet of the solar system. Its Rock has not been formed yet. Its surface is only a 2.5million years old.
How could have Venus renewed its surface?
It is another interesting fact to be discussed about Venus. Venus is a planet as old as our Earth. It is still not cooled down. Its surface is totally different from our Earth. During its evolution, 4.5 billion years ago, Venus was surrounded by thick clouds of CO2. Its surface was molten.
Like that of Earth, its atmosphere mostly consists of carbon dioxide. Its atmosphere was thicker than that of Earth. Its rotation is slower than its revolution. That its day (DAY+ NIGHT) is 243 Earth days long. Venus is closer to Sun so, it receives more radiation than Earth.
THE RUNAWAY GREENHOUSE EFFECT
(The runaway greenhouse effect occurs on Venus. because venus has a very high concentration of CO2 in its atmosphere, it receives more sunlight being closer to Sun, its day is 117earth days long. This has boiled its surface water, the water vapor escape to the atmosphere, converted into H2 and oxygen. This water never returned to Venus. This effect is called RUNAWAY GREENHOUSE EFFECT)
Moreover, carbon dioxide in its atmosphere does not allow the longwave radiation to pass out from its atmosphere and radiate the excessive heat it receives from Sun. that has heated away all its water.
The water is converted into water vapors when reached its atmosphere, where water is broken down into hydrogen and oxygen. The hydrogen is being light has escaped from its atmosphere. So, no water remains on its surface, this runaway or vaporization of all of Venus water is known as a runaway greenhouse effect.
ROCK FORMATION ON VENUS: THE RESURFACING OF VENUS
Being highly concentrated in carbon dioxide with no water on its surface, Venus has become hot to hell. It is the hottest planet in the solar system. It does not allow the heat to escape from its surface. Thus, it is behaving like a furnace.
Its runaway Greenhouse effect has made its condition totally different from that of Earth. Its surface has never cooled down, and its crust could develop into lighter silicate rocks as that is present on earth. Its core could not condense and become solid, like that of Earth. Due to a lack of cooling down, Venus could never form rocks and could never develop the plate tectonics that is present on earth.
Plate tectonics and folding and faulting are the processes that have resulted cooling down of Earth's crust that has resulted in the formation of mountain valleys and other landforms on earth. This has resulted in basalt Rocks sinking below the sea, the continent is made of granite.
However, basalt Rocks are present on the upper surface of Venus's crust. Volcanism still occurs on Venus All these facts Venus rocks are newer in age. Rocks are not cooled down to become and took final shape.
Its water has run away. It is surrounded by thick clouds of sulfuric acid and carbon dioxide. Whatever pores available in its atmosphere are clogged by water vapors making it a closed furnace with a high temperature reaching 475 degrees Celsius.
THE MAIN CHARACTERISTICS OF THE HELLISH VENUS
Thick clouds of CO2 on Venus have made its atmospheric pressure to be 90 times that of earth’s atmospheric pressure.
The Runaway greenhouse effect has vaporized all its water.
Longwave radiation cannot escape its atmosphere.
It is hot as a furnace.
This does not allow cooling down of its upper rocks.
Folding- faulting has not occurred, so landforms are not developed.
Internal heat circulation has not developed.
The oldest rock on Venus is only 2.5 million years old.
Its day is 117earth day long.
It smells like rotten egg.
All this has made it the most hellish planet in the solar systems.
Venus is earth's twin who took over a totally different journey after its formation.
If the concentration of CO2 keeps on increasing, the Runaway Greenhouse Effect can also be seen on Earth.
