Viscosity is the resistance to flow (opposite of fluidity). Viscosity depends on primarily on the composition of the magma, and temperature. Higher SiO2 (silica) content magmas have higher viscosity than lower SiO2 content magmas (viscosity increases with increasing SiO2 concentration in the magma). Lower temperature magmas have higher viscosity than higher temperature magmas (viscosity decreases with increasing temperature of the magma).
Google does not specifically recommend either DirectX or OpenGL for Google Earth. You can configure Google Earth to operate in either DirectX or OpenGL rendering modes.If your system crashes or performs poorly in one mode, Google recommends you switch to the other mode.penGL Overview. OpenGL is a platform-neutral, open API for rendering graphic images. Although the API is different, OpenGL provides Google Earth with the same graphics performance enhancements as DirectX. OpenGL was originally developed by Silicon Graphics Incorporated.
Yes, you can use the Google Maps V3 to switch between Google Maps and the Google Earth Plug-in. The google-maps-utility-library-v3 can be used to make this easier. You can see a working example here.Alternatively you can simulate a reasonable map view buy just turning of the terrain and photo imagery and turning on the borders and roads layers in the Earth Plug-in. am developing a web page which uses the Google Earth plugin. I would like to display the map like in the first image with the Earth and Satellite/Map view options like you can in Google Maps, or at least be able to just show the map in Satellite/Map view:
