2.1. Coastal Systems

• A coastal system refers to the interconnected components that make up a coastal environment, including the land, sea, and atmosphere
• Match the coastal process with its description:

  Erosion ↔️ Wearing away of coastal landforms

  Transportation ↔️ Moving eroded material along the coast

  Deposition ↔️ Accumulation of sediment to build landforms
• What is the primary factor influencing deposition in coastal systems?

  Wave energy
• Coastal systems include interconnected components such as land, sea, and atmosphere.

  True
• Erosion refers to the wearing away of coastal landforms due to wave action, weathering, and biological activity
• Order the key processes involved in coastal system dynamics:

  1️⃣ Erosion

  2️⃣ Transportation

  3️⃣ Deposition
• The energy level in erosional coastal systems is high
• What type of erosion involves waves using sediments to grind down rock surfaces?

  Abrasion
• Key components of a coastal system include the land, sea, and atmosphere
• Longshore drift is a type of transportation that moves sediment parallel to the shoreline.


  True
• Erosional coastal systems are characterized by high-energy environments and dominant erosion processes.


  True
• What is the dominant process in depositional coastal systems?

  Deposition
• Solution is the process of waves dissolving soluble minerals in coastal rocks.

  True
• Order the processes in a depositional coastal system:

  1️⃣ Sediment transport

  2️⃣ Sediment accumulation

  3️⃣ Formation of beaches and sand dunes
• What is an extended ridge of sand attached to the mainland called?

  Spit
• What role does sediment supply play in coastal systems?

  Builds coastal landforms
• Changes in one component of a coastal system affect the others.


  True
• Weather patterns in the atmosphere affect coastal climate and erosion rates.

  True
• What is the term for waves compressing air in cracks to fracture rocks?

  Hydraulic action
• The movement of sediment parallel to the shoreline is called longshore drift
• Decreasing wave energy allows sediment to settle
• Match the coastal process with its description:

  Erosion ↔️ Wearing away of coastal landforms

  Transportation ↔️ Moving eroded material

  Deposition ↔️ Accumulation of sediment
• Longshore drift is the movement of sediment parallel to the shoreline
• Match the coastal process with its key factor:

  Erosion ↔️ Hydraulic action

  Transportation ↔️ Tidal currents

  Deposition ↔️ Sediment supply
• What type of coastal system has low energy and builds landforms with sediment?

  Depositional
• What are two causes of coastal flooding in coastal systems?

  Storm surges and rising sea levels
• The availability of sediment in the ocean affects coastal deposition.


  True
• The energy of waves is influenced by the coastal morphology
• Order the following human activities based on their increasing impact on coastal systems:

  1️⃣ Coastal Tourism

  2️⃣ Overfishing

  3️⃣ Pollution

  4️⃣ Coastal Development
• Discharge of oil spills contaminates coastal waters, harming marine ecosystems and biodiversity
• Match the coastal management strategy with its description:

  ICZM ↔️ Balances environmental, economic, and social needs.

  Protected Areas ↔️ Conserves biodiversity and fragile ecosystems.

  Engineering Solutions ↔️ Protects infrastructure from erosion using structures like seawalls.
• What three factors must effective coastal management balance?

  Conservation, economy, social equity
• Match the coastal system feature with its type:

  High energy level ↔️ Erosional

  Low energy level ↔️ Depositional
• Hydraulic action involves waves compressing air in cracks
• Steep rock faces carved by wave erosion are called cliffs
• Accumulations of sand along the shoreline are called beaches
• The energy of waves is influenced by the coastal morphology
• Rising sea levels and storm surges can lead to coastal flooding
• Landforms such as cliffs, beaches, and dunes are key components of the land
• Match the coastal system component with its role:

  Land ↔️ Shapes the coastline

  Sea ↔️ Drives wave action

  Atmosphere ↔️ Affects storms and erosion
