2.2C Geological structure and cliff profiles

• Cliff profile = influenced by geology, especially the resistance (to erosion) of the rock, and the dip of rock strata in relation to the coastline. 
• Joint = fractures in rocks created without displacement

  -> occur in most rocks, often in regular patterns, dividing rock strata up into blocks with a regular shape

  
• Faults = major fractures in rock created by tectonic forces, with displacement of rocks either side of the fault line

  
• Folds = bends in rocks produced by sedimentary rock layers being squeezed together by tectonic forces

  
• Dip = Angle of inclination of the rock strata from the horizontal
