coast

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

  It receives inputs from the lithosphere, atmosphere, hydrosphere, biosphere, and cryosphere
• In what context can the coast be viewed as a closed system?

  When examining a specific sediment cell during research and coastline management
• What are examples of feedback mechanisms at the coast?

  • Positive feedback: Waves erode cliffs, releasing material that further erodes the cliff.
  • Negative feedback: Erosion widens the wave cut platform, absorbing wave energy and reducing cliff impact.
• What happens to the cliff as waves erode it?

  Material is released, which abrades the cliff and causes more erosion
• How does the wave cut platform affect cliff erosion?

  It absorbs wave energy and reduces the impact at the base of the cliff
• How are coastal systems linked to other natural systems?

  They are closely linked to human and physical systems like atmospheric weather and agricultural systems
• How does the climate system relate to coastal systems?

  Global sea levels during cold glacial periods affect coastal landforms and processes
• What occurred during the last ice age regarding the UK and France?

  The UK was connected to France by a land bridge due to low sea levels
• How do current changes in the global carbon cycle affect coastal regions?

  They lead to faster erosion and greater risk of coastal flooding
• What role do coastal systems play in the wider landscape?

  They are where the land mass meets the sea and interact with other systems
• What are some distinctive landforms found at the coast?

  Landforms created partly by wind or rivers
• What does the interaction of coastal landforms with other geographical systems illustrate?

  • Coastal landforms are influenced by wind and rivers.
  • They demonstrate the interconnectedness of natural systems.
  • They highlight the complexity of coastal landscapes.
