Google Earth uses a Simple Cylindrical projection with a WGS84 datum for its imagery base.
Google Maps does not cover the area around the north and south pole. This is due to the use of standard map projection. Google Earth is used to cover these areas.
Equal-Area projection
the relationship is complicated.. you should use google to find it
One uses Google Earth to get directions as Google Earth provides geographical information about places on the Earth. Google Earth was released twelve years ago in 2001.
The Earth is a sphere. Maps are almost always flat. The method you decide to use in order to represent the highlights of a curved surface on a flat drawing is called the 'projection'.

Google Earth uses a "Simple Cylindrical projection," which is also known as Plate Carrée, with a World Geodetic System of 1984 (WGS84) datum.This is a simple map projection where the meridians and parallels are equidistant, straight lines, with the two sets crossing at right angles.Google Maps uses the Mercator projection also with the WGS84 dataum.The vertical component (altitude) is measured from the vertical datum, which is the Earth Gravitational Model 1996 (EGM96) Geoid. Altitudes are measured in meters.
No. Google Earth can only be downloaded from google's website. There is a free version and a Pro version for business use.
In order to use Google Earth you need to download the application. There are versions of Google earth for all sorts of mobile devices available for download.
