On the Earth, how does plate velocity vary with distance from the pole of rotation?
Mnenie [13.5K]

Answer:

Yes, the length of plate widening started from the poles and extends towards the other poles

Explanation:

  • As the aspects of spherical geometry, the relative plate motion is affected by the rotation of the earth on its axis and not all are located at the geographic poles. As an example of mid-oceanic ridges that have a spreading value of 37-40 mm/year in southern Atlantic.
  • Hene rotation of the poles can be determined by the accuracy an orientation of the mid-Atlantic ridges. Another example is of the African plate is moving to the east and the northern plate is moving to the west as template rotation is anticlockwise and paleomagnetism pole is and evident to this phenomenon.
  • Spreading and splitting of the supercontinent like Pangaea created a major displacement in the orient rock and thus led by the rotation of the earth, this phenomenon also called the Euler pole and rotation angle based on the earth's orbit around the sun.

The __________ is the layer of the atmosphere where satellites and the space shuttle orbit the Earth.
Lady_Fox [76]
The answer is D. Exosphere

Exosphere is the outermost Layer of the Atmosphere that goes out about 500 - 10,000 Km in altitude.

It's the place where satellites and the space shuttle orbit the earth. Because it's difficult to define the boundary between exosphere and the outer space, exosphere may be considered as a part of outer space
