| 1. | The dip angle, forming a ridge that appears at the Eiger and south of the Jungfrau mountain.
|
| 2. | The unconformity consists of a polymictite breccia that varies in both thickness and dip angle depending on location.
|
| 3. | Along converging plate margins, the dip angle of the rupture plane is very shallow, typically about 10 degrees.
|
| 4. | He then stood at the highest point of the mountain, where he measured the dip angle using an astrolabe.
|
| 5. | Here, the Pacific Plate is being subducted under the North American Plate at a dip angle of nearly 45?
|
| 6. | Georg Hartmann first discovered dip angle in 1544, when he noticed the needle on a compass dipped towards the north hemisphere.
|
| 7. | However, Robert Norman around 1576 investigated dip angle further and in 1581 described in print a device to measure this phenomenon.
|
| 8. | For example, the orientation in space of a normal to that plane, or by using the strike and dip angles.
|
| 9. | The geometry of a slab window depends primarily on the angle the ridge intersects the subduction zone and the dip angle of the down-going plate.
|
| 10. | Linear features are measured with very similar methods, where " plunge " is the dip angle and " trend " is analogous to the dip direction value.
