What is Venus mostly made out of?

Answer 1

Made out of a centural iron core and a rocky mantle.
The atmosphere of Venus is incredibly dense and cloud covered. The clouds are made of sulfuric acid droplets and sulfur dioxide (instead of water). If you were on the surface of the planet, the air above you is like being 1km under the ocean (or over 90 times heavier than the Earth's atmosphere). This is like what a submarine experiences at 3000 ft below the surface of the Earth's ocean. The atmosphere is composed mainly of carbon dioxide (96%), 3.5% nitrogen, and less than 1% is made up of carbon monoxide, argon, sulfur dioxide, and water vapor. The intense surface of Venus with the pressure and cloud cover can cause Venus to be incredibly hot - hotter than even Mercury at around 740K.

All this carbon dioxide in the air has produced at strong greenhouse effect, which traps heat in the atmosphere. A small amount of sunlight can penetrate the planet's thick cloud layer (about 2%) without being reflected by the sulfuric acid clouds or absorbed by the atmosphere. Whatever sunlight does make it through heats the surface, and is re-emitted in the infrared. But virtually all energy emitted by the planet in the infrared (heat radiation) is absorbed by the carbon dioxide rich air. The result is unusually high surface temperatures of about 460C (860F).

Why should Venus and not the Earth have a hot and thick atmosphere? Some scientists call it the Goldilocks phenomenon.

Measurements made by probes which travelled through the atmosphere have shown that temperature varies no more than a few degrees from the equator to the poles, and that the atmospheric temperature remains nearly constant through the long dark night. Thus there are no significant daily, seasonal, or latitudinal temperature gradients in the atmosphere.

Answer 2

Venus is similar in composition to Earth. It has a crust and mantle composed mostly of silicate minerals and a core of iron and nickel.

Answer 3

The planet Venus is made up of a small rocky planet blanketed in a thick layer of yellow clouds.

Answer 4

People think it is similar to Earth's mantle: an iron core about 3000 km in radius, maybe molten rock.

Answer 5

It is probably made of peridotite, much like Earth's mantle.

Answer 6

liguid and gas mostly gas

Answer 7

butts and bugs

Answer 8

It's compose of dense rock.

Answer 9

Carbon dioxide.

Answer 10

core of the earth
