I have been told that there are other women besides my wife. They say that some are much more slender than her and they are also always in good humor, caring for you, caress you hair all the time while you get grapes ... It must be wonderful to share life with those women. But I guess that also must be worse than my wife (we, I say). So how should women be in reality? I guess like everything must be very difficult to generalize.
But it is inevitable that one will get an idea of \u200b\u200bwhat they are looking at the examples of things around it. That is, the woman I know best is the one which lives with me. With my wife I think a general idea of \u200b\u200bhow women are. As it is not the only woman in the universe, from time to time I talk to someone else and find that not all women think alike on everything. So my idea of \u200b\u200bwhat a woman I add these details (there are more lean, the more unfriendly, there are a lot like buying them, others do not like, some are very jealous, others love football , ...). But of course, the fuller picture what is a woman gives me the closest example I know best.
Similarly, if you want to know how are the planets of the Solar System'd better put me first to see what the world I live with every day and then, when she meets the other planets, compare with the case I know best to begin to get an idea of \u200b\u200bwhat (or how) the planets.
Well, before we turn our spacecraft to other planets, let's take a moment to look at Earth. The Voyager 1 spacecraft in 1991, did just that: to photograph the Earth from the vicinity of Neptune. Earth from afar It looks like a pale blue dot in the sky.
Earth from Neptune looks like a pale blue dot in the sky.
Since so far no one would say that the Earth has many things on its surface. To get a bit closer to the Earth we see that there is only blue. He has brown areas (continents), blue (sea of \u200b\u200bliquid water) and white (clouds). The oceans cover about 3 / 4 parts of the Earth's surface and the remaining continents.
Earth's surface is blue areas (oceans and seas) Brown (continents) and
white (clouds) from Neptune looks like a pale blue dot in the sky.
Although at times the separation between sea and land is unclear. For example, in the Ebro delta land seems to invade the sea. And the inhabitants of the Canary Islands are well aware of how many you want to take away the land of the hegemony of the sea, because occasionally they come through the air a lot of Saharan dust darkening the skies even in daylight.

The interior of the Earth is geologically active. This means that inside the Earth there is enough pressure and latent heat to melt the material and only the outer part has been cool going to be solid. This solid layer slips over the molten material causing earthquakes to rupture. From time to time also, the liquid material (lava) on the inside comes out by volcanoes.

Earth is covered with a gaseous atmosphere composed of nitrogen, oxygen, water vapor. This vapor waters from the oceans and sometimes brings rain storms and even hurricanes with strong winds.

The image of Earth from Voyager 1 is difficult to know whether the Earth's living beings. But one could ever know. Do you know how? Well, thanks to sales of cattle. It turns out that the Earth's atmosphere has a lot of methane. Methane breaks down very easily with sunlight and can only be permanently in the atmosphere if there is a constant production mechanism. It is true that volcanoes emit too much methane, but if we consider that the Earth's atmosphere plenty of oxygen (produced by plants), we see that an atmosphere has many numbers to belong to an inhabited planet.
The presence of oxygen or methane alone will not mean anything, but the fact that they are the two together is very suspicious. If we saw a planet with the atmosphere we may suspect that this is an inhabited planet. So the next time I take my wife to throw me a fart anger I will say that I am sending signals to the aliens so they know that there is life on Earth. To see if school. If I promise to give up school slender silhouettes.
