Question: 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 more rocks break apart on less or slower erosion of rocks.?

Answer: against


Question: Process:  -Solar radiation reaches Earth's atmosphere -Some is reflected back into space -The rest of the energy is absorbed by land and oceans, heating the Earth -Heat radiates from Earth to space -Some of this heat is trapped by greenhouse gases in the atmosphere -Human activities such as burning fuel are increasing the amount of greenhouses gases -This causes more heat radiation to stay trapped in our atmosphere -The Earth's temperature rises -
 Question: What is the effect of Bread is sealed away from the elements on a greater greenhouse effect.?

Answer: none
