Dynamic Earth


The rocks and landscape around us appear unchanging and permanent, but careful observation can detect the effects of weathering and erosion on exposed rocks,and the laying down of sedimentsthat in the right conditions can be changed into new rock.Longer term processes transform rocks deep underground and bring fresh rock to the surface.Understanding the dynamic Earth helps us to identify and utilise resources it contains and to find ways to build a sustainable and environmentally stable future.
