Coastal Landscapes - OCR A-Level Chapters 1-3

What is a system in the context of coastal landscapes?

• A collection of unrelated processes

• A set of interrelated objects comprising stores and processes

• A single process causing erosion

• A closed loop of sediment storage

What types of energy are involved in coastal landscape systems?

• Kinetic, thermal, and chemical

• Potential, thermal, and kinetic

• Nuclear, thermal, and gravitational

• Electrical, potential, and kinetic

What is the main material found in coastal landscape systems?

• Clay deposited in deep sea trenches

• Sediment found on beaches, in estuaries, and nearshore zones

• Rocks eroded from mountains

• Sand transported through the atmosphere

What defines an 'open system' in coastal landscapes?

• Energy and material are constantly transferred across system boundaries

• No external energy or material is transferred

• The system stores energy but does not release it

• The system operates within a fixed time scale

Which geomorphic process primarily influences coastal landscape systems?

• Deposition and wind erosion

• Fluvial erosion only

• Natural geomorphic processes

• Chemical weathering exclusively

How long can processes in coastal systems take to occur?

• Days to millennia

• Seconds to minutes

• Years to centuries only

• Hours to decades

Where is sediment predominantly found in coastal systems?

• On riverbeds and floodplains

• In the nearshore zone, beaches, and estuaries

• On mountain slopes and plateaus

• In caves and underground rivers

Which of the following is NOT a component of a coastal open system?

• Inputs

• Outputs

• Stores

• Electrical energy

What is the primary energy source driving coastal systems?

• Thermal energy from the Sun

• Wind-generated kinetic energy

• Tectonic energy from Earth’s core

• Gravitational energy from the Moon

What happens in an open coastal system when energy decreases?

• More sediment is transferred

• The system's ability to perform work decreases

• Waves erode cliffs faster

• The sediment input rises
