A fossil is a traces or remainings of plants and animals that lived in the past. The fossil record provides evidence of a common ancestor to many species is the option that best describes the fossil record.

Resistivity :

Resistivity is a measure of the resistance to the flow of electrons. 

Conductivity :

Conductivity is just the inverse of resistivity, σ = 1/ρ, where σ is conductivity and ρ is resistivity.

Example:

Think of a pipe and water, the bigger the pipe, the easier water can flow and thus the lower the resistance. 

All of the factors that contribute to global winds are 

1) Uneven warming of the earth by the sun
2) Coriolis Effect
3) Convection Cells
