• Negative feedback is a cyclical sequence of events that neutralises the effect of a system, promoting stability
• Dynamic equilibrium represents a state of balance within a constanconstantly changing sytem
• Positive feedback loops exacerbates the outputs of a system, driving it in one direction and promoting environmental instability
• Sublimation is the transfer from a solid state to a gaseous state and vice versa
• Percolation is when water soakes into rocks
• Overland flow transfers of water over the land surface
• ITCZ is the inter tropical convergence zone
