Down
  1. 1. variable you want to measure your results against or variables that remain unchanged
  2. 2. The latitude that receives the most intense sunlight, which causes the ascending branches of the two Hadley cell to converge
  3. 3. where the distribution maintains similar distances away from another
  4. 4. where there is no pattern to the distribution
  5. 6. the system tries to return to its original state or decreases the rate at which the change is occurring
