Also the second largest impact structure on Earth, the 1.85 billion years old Sudbury crater in Canada, hosts world-class mineral deposits - in this case nickel-rich minerals that were melted and concentrated by the extreme heating caused by the impact.
The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole â the meridional circumference â Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.
What is the max file size to open a KMZ* in Google Earth. Your limit is likely not the file size (though 2gb is pretty massive), but rather the image size in pixels. The maximum image size you can load into Earth for an Overlay is based on the capabilities of your computer's graphics card. If you go to Help >> About Google Earth (somewhere else on Mac), you'll see a line about Max Texture Size, which indicates this limit. Most are 4096x4096 or 8192x8192, though some are lower and some are higher.
