The atmosphere of the Earth is held in place by its gravity, and its a good thing for us that it is. All of the planets in our solar system have an atmosphere of some kind, though Earth is the only planet that has free oxygen in the atmosphere....
The atmosphere around a planet or moon is held in place by the gravity of this central body. For this reason, the smaller and lighter planets and moons do not have atmospheres, while the heavier ones do.Answer and Explanation: The Kuiper belt is a large and cold region of space, not a...
“自然”温室效back into space at longer wave lengths. Greenhouse应指的是来自太阳的gases in the atmosphere, such as methane and热量进入大气层,并carbon dioxide, trap some of the heat, keeping以短波辐射的形式使Earth's climate warm and habitable [6]. Without地球表面变暖。 热量this process, Earth...
So yes, Virginia, outer space does have a temperature, and it is a very cold one. But even if that temperature was 0 K (in which case one might metaphysically ask whether zero absolute temperature actually means no temperature), the practical result would be the same: the thermal radiation...
根据“radiation from the sun is blocked by the greenhouse gases and not reflected back into space”可知,太阳辐射被温室气体阻挡,不会反射回太空,这让大气中保留了更多的热量。atmosphere“大气”,符合语境。故填atmosphere。 ⑤考查动词短语。句意:这是怎么发生的?此处询问这件事情是如何发生的。come about“...
At that time Mars would have been much warmer and wetter than it is today with an atmosphere composed mainly of carbon dioxide just like that of the earth at the time. Under these conditions it is highly probable that life may have arisen on Mars as well.But even if life did not arise...
Their theory about the nature of the atmosphere was that nothing was holding it down. So, if, if you can understand that way of thinking, then clearly, if the Earth, was moving at a great speed, we should have lost all our atmosphere a long time ago. You know, it would be, like,...
They have even been found on Venus, which lacks a magnetic field; there they have formed from transient fields created by solar wind barreling into the planet’s atmosphere. 自此以来,科学家们已经在太阳系中几乎所有拥有磁场的行星上发现了合唱波,包括水星、火星、木星、土星、天王星和海王星。甚至在...
We have to dig them up or drill a well to release them. And this is carbon that was in the atmosphere millions of years ago. So what happens is: when we burn this carbon, ok, it doesn't really release a whole lot compared to the amount that's already there in the atmosphere, but...
NASA's Cassini spacecraftidentified an unknown chemical in Titan's hazy atmospherethatNASA laboratory experimentson Earth determined was a molecule containing nitrogen, methane and benzene and belonging to a family of molecules called polycyclic aromatic nitrogen heterocycles (PANHs). In particular, it'...
