Salt domes result when: 1. inland seas dry 2.the pressure of overlying rock forces the salt to rise 3. a layer of sedimentary sa
Ilia_Sergeevich [38]

Answer:

Salt domes result when <u><em>the pressure of overlying rock forces the salt to rise. (Option 2)</em></u>

Explanation:

In geology it is called the gently wavy and rounded relief dome.

Salt has some special properties like rock:

  • Salt has a lower specific gravity in relation to a common mineral.
  • Salts deform plastically and are very mobile.
  • Salts have a high water solubility.

These properties allow, if the pressure is very high, that the salt layers move upwards (due to their lower density). That is, the internal forces produce the elevation of the strata by means of the pressure they exert towards a higher point, generating that the salt looks for its way towards the surface [that is, the salt ascends through the sedimentary layers of the earth's crust, crossing them and deforming them] and causing the bulging structure. The oldest strata are located in the central area of the dome, while the most modern are distributed in the farthest radius. The structure is called salt or diapiro dome, the phenomenon by which it is formed is called diapirism.

Finally, you can say that <u><em>Salt domes result when the pressure of overlying rock forces the salt to rise.</em></u>

Carbon has four valence electrons. true false
8090 [49]
The answer is true. One neutral atom of carbon has four valence electrons.
 
An easy way of finding out is to check out the periodic table and look at which main number group the element is in. Carbon is in group number four, which would mean it has four valence electrons.

Hope I was able to help!
