The Earth's Macroscopic Properties

and What They Can Tell Us


To get some very basic descriptions of the Earth we will start by describing some of the simplest of all the Earth's properties - how big, how heavy, how hot, how strong - and how they were deduced. The other world visitor would be remiss if he he did not at least provide a description of those properties. Most of them were deduced many years ago and represent some of the first specific inquiries into the nature of the planet we live on. Even these gross external properties can be used to infer quite a lot of information about the interior properties.
