| The sand seas or ergs cover thousands of square kilometres, and in places the sand cover may be hundreds of metres thick. |
|
| The reef is fairly small and has four tiny ergs, one with a hole right through it, in the east side of which a sea fan grows. |
|
| There are no ergs, joules, electron-volts, calories, or foot-pounds of New Age energy. |
|
| One rad equals 100 ergs of absorbed energy per gram of target matter. |
|
| The navigation will be a key element, as it will be necessary to find the the best passes to get over some difficult ergs, through breathtaking landscapes. |
|
| Competitors face a technical track never previously used in the Dakar that requires careful navigation through breathtaking passes and over unavoidable ergs. |
|
| One supernova, in 1054, was thought by many to herald the biblical Day of Judgment. We have reached an energy level of 10 quindecillion ergs, or 1049 ergs. |
