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.
Developer of GIS applications and advanced geospatial visualization including Google Earth and KML. The only real difference is that opening in  OpenGL  GE is using the memory that is dedicated on your graphics card, not your system resources.If you have a graphics card installed in your computer that is capable of handling the memory requirements of the GE program, you open with  OpenGL .If you computers graphic card has to use your systems memory (RAM) then you would open using DirectX.This is Microsoft's way of letting you enjoy the 3D effects of many programs. When you first install and run GE for the first time, it should tell you which mode to open in and then set it as your default.oogle is the name for the company and product. Googleplex is the nickname for the location where Google headquarters is in California. Edit.
