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.
Google Earth is for exploring. For the explorer in all of us, Google Earth is worth having around. Even though Google Maps offers a basic satellite view, if you want to really look around and see what things are like, you need to open Earth instead.oogle Maps contains all of the navigation, lightweight mapping power and points of interest with just a small hint of satellite imagery, while Google Earth has complete 3D satellite data and just a small subset of information on places, without any point-to-point navigation.
