Venus, Earth and Mars: Atmosphere and the Myth the Habitable Zone

[LeDavidBeasley]

hmmm idiots

[rainbowhiker]

I have read where life couldn't exist on earth without the moon. If this has any truth, and let's assume for the sake of this questiong that it is, what would be the effects of a tidal-effect inducing moon, mathematically sized and distanced from Mars and Venus, on those two other planets? Thanks.

This is simple, venus and mars have no protective magnetic field. The only reason venus has an atmosphere and the type it does is from constant surface renewal. These facts are 100% correct and extremely simplistic in nature.

Then why didn't the parachute melt on Venus?

DEAR VIEWERS, FOR ASTONISHING FACTS ABOUT PLANETS, JUST TYPE IN THE SEARCHING BOX:

SEVEN PARTS! YOU MUST LIKE THEM!

Venus is too hot because of a runaway greenhouse effect, not because its too close to the sun. And Mars is too cold, because it dosen't have anything holding in heat like Venus and the Earth.

[barbm001]

the problem with venus is that it has way to many volcanoes that caused its global warming(greenhouse). plus for unknown reasons venus spins backwards. venus= a failed earth. if venus didnt have so much volcanoes. the atmosphere would be different.

[kaboose1994]

@barbm001 so there might be a chance to control it, by somehow destroying volcanoes? i'd like dat

[barbm001]

@kaboose1994 i also think that it has the same problem as jupiter's moon IO. and to destroy the volcanoes, you must destroy the planet's core. might aswell leave venus the way it is :)

[kaboose1994]

@barbm001 yeah we should just go plant trees and sunflowers on mars and then we will have an awesome neighbor planet with hippies

[4lyfesports]

@barbm001 they say that venus was once alot like earth in almost every way, so really if you think bout it when you look at venus your really looking at the future of what our planet might be ... and mars will become earth and the cycle continues .. brilliant we just got to jump planets not to hard

[TheMrSpam]

if we smack, mars and venus onto eachother in 1000 years when technology is ready. we will form,

EARTH 2.0

Please make notice here that CARBON IS NOT A GREENHOUSE GAS. Venus is a prime example of how that is an insane claim.

[RestleStudiosTV]

@Batta0909 carbon isnt a greenhouse gas BUT carbon dioxide IS .......

[EarthianLifeForm]

Luna's gained distance from Earth caused tidle forces to weaken too much in which it could not sustain volcanic activity to produce and sustain an atmosphere. For Mars, if it had one or more moons it could have slowed the cooling down enough for Mars to still have volcanic activity which would have sustained a dense atmosphere to trap enough heat to keep water in liquid state, if the moons stay close to Mars to sustain warmth, they could have sustained a dense atmosphere and give birth to life.

[EarthianLifeForm]

Venus, Earth, Earth's one single moon "Luna" in it's Earthian moon system, and Mars, are all in the habital temperature zone. It's sad that only one body out of 4 ended up with the proper characteristics to give birth to life. I think Venus formed a rotatation speed that's to slow (about 58 Earth days just to go from sunrise to sunset) and got too hot on the daytime side causing it's water to turn to gas faster than it turns back to liquid through precipitation.

good! video

[eepruls]

Great video! Seriously, good job. I like the voice of the narrator. He sounds like the actor that played a young Jean-Luc Picard in Star Trek:TNG's "Rascals"!

[CrownChanel]

@eepruls it's a he?

[eepruls]

@CrownChanel Yes, the narrator is male.

[lenovoservice1]

Venus and Mars is also in habitable zone.Venus is very hot but the sun is not causing to venus to heat up.The planet Venus heat up by itself beacuse lot of CO2 escaped from the mauntain.Mars need more CO2 to heat up. have enough CO2 then mars can support life.If Venus can dump some CO2 and Mars can have some more CO2 then both of the planet can be like a earth like planet that support life.

[Agogaraxis]

if mars had a better magnetic field set up and atmosphere it might be in the "habitable zone"

[1968DodgePolara]

that can be true Mars lacks the magnetic field and the atmosphere but the rotation is alot like earth 26 hour days Mars has. Most of the factors there but just falling short Now I do beleave plants can grow on Mars if man can build green houses on Mars adding water and regulate the temps in the houses useing the CO2 from Mars atmophere to let the plants breath in return Oxegen will be let out from the plants.Mars is close enought too the Sun too feed the plants .

[Agogaraxis]

the sun could feed the plants.

i remember there was a biosphere containment experiment on earth but it failed if i remember correctly. If i remember right, it was because some bad bacteria was destroying the plants inside the closed off environment.

[1968DodgePolara]

well that might work on Mars a biosphere containment with no bacteria on Mars a start with clean water and seeds nothing harmful too wipe out the plans growing except a malfuction in the biosphere.

[brundukas]

but the moon does not have any atmosphera

[tinygirl505]

another problem with the idea of a 'habitable zone' is that the Earth's moon also lies perfectly in that zone, yet is 'uninhabitable'

[jeannshi]

Good point that lead me to believe, it's not a chance we are here

[1968DodgePolara]

the Moon is too small alot less gravity too hold an atmosphere plus the rotation speed is alot slower than Earth even if Earth rotation speed is slower than what it is now days will be too hot and nights too cold alot of factors has to be in place befor a planet can be called "habitable zone" too support life like us
