organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
