Which characteristic is shared by extrusions, intrusions, and faults? All are cracks.
All are igneous rocks.
All cause gaps in the geologic record.
All are younger than surrounding rocks.

the temperature and the pressure affect solubility. temperature affects by changing the properties of the solvent. the increase in pressure increases solubility, the decrease in pressure decreases solubility.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
