Magnetic dip causes the compass to dip upward or downward depending on the latitude. Illustration of magnetic dip from Norman's book, The Newe Attractive. Magnetic dip, dip angle, or magnetic inclination is the angle made with the horizontal by Earth's magnetic field lines. This angle varies at different points on Earth's surface.
A feature's orientation can also be represented by dip and dip direction, using the azimuth of the dip rather than the strike value. Linear features are similarly measured with trend and plunge, where "trend" is analogous to dip direction and "plunge" is the dip angle. [3] Strike and dip are measured using a compass and a clinometer. A compass ...
Dip angle may refer to: Magnetic dip, the angle of the Earth's magnetic field lines relative to the horizontal; Dip (geology), the angle of a planar geological feature relative to the horizontal; Dip angle, the angle between the apparent and the astronomical horizons
Reason: The dip angle is designated here as the angle between the dipe line of the „real“ (i.e. the red/pink) plane and the East direction. Since the real plane does not strike in N-S direction, there has to be a dip direction line within the horizontal plane which is oriented 90° to the strike line and not identical to the East direction.
A dip circle by P. Gruber, Vienna, from before 1900. Dip circles (also dip needles) are used to measure the angle between the horizon and the Earth's magnetic field (the dip angle). They were used in surveying, mining and prospecting as well as for the demonstration and study of magnetism.
English: The Earth's magnetic field runs parallel to its surface only at the Magnetic Equator, which is the point halfway between the Magnetic North and South Poles. As you move away from the Magnetic Equator towards the magnetic poles, the angle created by the vertical pull of the Earth's magnetic field in relation to the Earth’s surface increases gradually.
The user may choose to replace the inclination angle by its complement, the elevation angle (or altitude angle), measured upward between the reference plane and the radial line—i.e., from the reference plane upward (towards to the positive z-axis) to the radial line. The depression angle is the negative of the elevation angle.
A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. [1] [2]Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space.
