The rubbing creates a negative charge that is carried by electrons. The electrons can build up t produce static electricity.

Neither plate subducts because the crust have approximately the same density. Instead, the rocks are smashed together causing them to recrystallize due to the intense heat and pressure from the colliding plates.
Matter is everything around you, atoms and molecules are all composed of matter.
Answer:
Tetrahedral
Trigonal pyramidal
less than 109.5°
Explanation:
If a molecule has a hybridization of sp3 it must have four electron domains which corresponds to a tetrahedral geometry.
Now we were told that the molecule also has one lone pair. It means that one out of the four electron domains is composed of a lone pair. Thus the molecular geometry will be trigonal pyramidal (e.g NH3).
Recall that lone pairs usually decrease the bond angle to a value less than the expected value for that particular electron domain geometry.
The expected bond angle for a tetrahedral geometry is 109.5° but that of the trigonal planar geometry is less than this.
