Q: Process:  -Sunlight shines on plants -Cells with chlorophyll in them capture the light energy -Plants absorb carbon dioxide through their stoma -Plants absorb water through their roots and other parts of themselves -Plants absorb minerals through their roots -Plants convert these inputs into sugars -Sugars can be used as energy sources -Oxygen and water are also produced -Excess water and oxygen are released through stoma and other parts of the plant.
 Question: What is the effect of more conversion into sugars on more sugar and oxygen being produced.?

A: for

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 rocks are in a climate that does not usuallly experience freezing weather on less or slower erosion of rocks.?

A:
for
