As rocks move through the rock cycle, their mineral compositions and physical structures change to reflect the processes under which they are formed. Which of the following provides the driving force for changes on Earth's surface, Earth's layers, and the rock cycle?

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
