[Q]: Process:  -Coal is loaded into the firebox -The boiler produces steam under high pressure -The steam generated in the boiler flows down into a cylinder -Just ahead of the wheels, pushing a tight-fitting plunger, the piston -The piston is connected to one or more of the locomotive&#x27;s wheels through a kind of arm-elbow-shoulder joint called a crank and connecting rod -As the piston pushes, the crank and connecting rod turn the locomotive&#x27;s wheels and power the train along -An outlet valve opens and the piston pushes the steam back through the cylinder and out up the locomotive&#x27;s chimney -

[Q]: Process:  -When water freezes it becomes 10% bigger, or takes up 10% more space -As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it -The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack -Clay expends when wet like ice does -This causes rock to break apart -Some plants like mosses and lichens are capable of growing without soil on bare rock -When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks -
 Question: What is the effect of the moss is afflicted with a moss killing disease on more roots grow into rocks.?
[A]: against
