Answer 3

The Earth's crust is called the crust because it is the outermost layer of the Earth, similar to the crust of a pie. It is the thinnest and coolest layer of the Earth, making up the solid surface where we live.

Answer 4

The word "Earth" is Old English and German in origin, related to the Old Saxon 'ertha', the Dutch 'aerde', and the German 'erda'.

I'm not really an expert on words and word origins, but it seems likely that people used Earth to mean 'land' and then it was the natural thing to refer to all the land and the planet.

Even the Oxford English Dictionary (online) admits:

"Men's notions of the shape and position of the earth have so greatly changed since Old Teutonic times, while the language of the older notions has long outlived them, that it is very difficult to arrange the senses and applications of the word in any historical order."

Answer 5

Various names have been proposed, including Terra and Tellus, which are other words that mean "dirt". The planet Earth never really needed a formal name, because back when people were inventing such names, Earth was the only world we knew about. And you don't need a proper name for something if it's the only one like it.
