classification of coasts

• Define lithology

  rock type + characteristics
• define structure

  arrangement and characteristics of rock units including fracturing, folding and orientation
• coastal classifications with geology

  concordant, discordant, rocky, sandy, estuarine
• classification of coasts due to sea level change

  emergent, submergent
• how are the uks sea levels changing

  -scotland was 'weighed down' by ice and glaciers so after melting, scotland is lifting out of the water and EMERGING

  -midland = unchanging

  -south/wales = SUBMERGING due to climate change
• classification of coasts due to sediment gain/loss

  outbuilding, eroding due to net erosion or deposition
• what can groups of processes lead to

  advancing or retreating coasts
• short term processes

  outbuilding, eroding
• long term processes

  emergent, submergent
• classification due to energy inputs

  high/low energy coastline
