coasts as a system

• What are the main components of a geographical system?

  Inputs, stores, transfers, and outputs
• What does a geographical system strive to achieve?

  A state of dynamic equilibrium
• How can the coast be classified in terms of systems?

  As both an open and closed system
• Why is the coast considered an open system?

  It receives inputs from various spheres
• In what context can the coast be seen as a closed system?

  When examining a specific sediment cell
• What happens as waves erode the cliff?

  Material is released, leading to more erosion
• How does the wave cut platform affect erosion?

  It absorbs wave energy, reducing cliff impact
• How are coastal systems linked to other systems?

  They are connected to human and physical systems
• What effect do cold glacial periods have on coastal systems?

  They lower global sea levels, affecting landforms
• What historical connection existed between the UK and France during the last ice age?

  A land bridge allowed crossing
• How do current changes in the global carbon cycle affect coastal regions?

  They increase erosion and flood risk
• What role do biotic and atmospheric systems play at the coast?

  They occur alongside coastal systems
• What are some distinctive landforms found at the coast?

  Cliffs, beaches, and wave-cut platforms
• How are coastal landforms created?

  By wind and river processes
• How do geographical systems interact within coastal landscapes?

  • Coastal systems meet land and sea
  • Interactions with biotic and atmospheric systems
  • Influence of wind and river processes on landforms
