The Earth is the 3rd planet of our own Solar System and logically the one which at the moment we lived. Its dimension is something superior for the one of Venus and comprises of the terraqueous planets Mars and Ceres along with. It includes a period of transfering round the Sun of 365.24 days and one inclination of his axis of twenty threeº what the year throughout entails modify of stations every 90 days to us with variable temperatures.
Its nitrogen atmosphere and I oxygenate for which the existence has been able to be shaped and to be developed, phenomenon that has at the moment not been capable of repeat in any satellite or planet of the Solar System, even though are indications of possible stable situation of life or possibility that there is it in the Titan Saturn moon, moon Io de Jupiter or the satellite Triton of Neptune. However in Mars, one presumes that it could have had a few indication of life from the geologic images however is not had absolutely to the certainty of it, absolutely, carries on being a pretty hypothesis.
The Earth surface temperature is actually 14° C. That is 57.2° F or 287 kelvin. As you probably understand, that number is only an average. The Earth’s temperature could be much higher or less than this temperature. In the hottest areas of the planet, in the deserts close to the equator, the temperature on Earth can easily get up to 57.7° C. And next in the coldest place, at the south pole in Antarctica, the temperature can dip down to -89° C.
The reason the typical temperature on planet is really high is due to the atmosphere. This works like a blanket, trapping infrared radiation near to the planet and warming it up. With no atmosphere, the temperature on planet would be more like the Moon, which increases to 116° C in the day after which dips down to -173° C during the night.
The magnetic field of our planet is pretty weak on the surface. In the end, the planet Earth is nearly 8,000 miles in diameter, therefore the magnetic field needs to travel a long distance to affect the compass. That's the reason a compass must have a lightweight magnet plus a frictionless bearing. Or else, there just is not enough power in the earth magnetic field to turn the needle.
The large bar magnet buried in the central analogy operates to explain why the planet has a magnetic field, however obviously that is not what exactly is really happening. So what is really happening?
Nobody knows for sure, however there is a functional theory presently making the rounds. The Earth's central is thought to comprise largely of molten iron. But at the very central, the pressure is really great that this superhot iron crystallizes to a solid. Convection due to heat radiating through the core, together with the rotation of the planet, causes the liquid iron to go in a rotational pattern. It is thought that these rotational forces in the liquid iron layer result in weak magnetic forces round the axis of spin.
