In a closed chamber (such as the lungs), as the volume of a gas increases the pressure decreases

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?

i believe the answer is snake.

the  different  of  these  two  are  that  they  differently  handle  their  team.

an  expressive  leader  focuses  on  the  task  at  hand  and  make  sures  that  their  goal  is  achieved.  they  accurately  finish  the  task.  an  instrumental  leader  on  the  other  hand  works  on  the  unity  of  the  group,  they  care  more  about  their  employees.  all  the  while  creating  a  good  environment.
