Entire Workbook Flashcards
what are the basic components of a system
inputs, outputs, processes/transfers, stores
what are some examples of inputs at the coast
energy from waves, wind, tides, currents
sediment
sea level change
what are some examples of transfers/processes
erosional processes, wind and water transport
what are some stores at the coast
erosional landforms and landscaped
depositional landforms and landscaped
what are some outputs at the coast
dissipation of wave energy
sediment removed beyond the sediment cell
what is our example of a low energy coastline
Chichester Harbour
what is a closed system
where energy is transferred across the system boundary but no matter is transferred
is the carbon cycle an open or closed system and why
closed, because all elements circulate so no matter passes out or in the system
is the global water cycle open and closed and why
closed because the planet doesn’t loose or gain water
is a river drainage system open or closed and why
open, because it has inputs and outputs of precipitation and outputs of water at the river mouth
what three kinds of properties do we find within the boundary of a system
elements
attributes
relationships
what are elements
the parts that make up a system
what are attributes
characteristics of the elements, for example quantity, size or volume etc
what are relationships
the associations that occur between elements and attributes
which system occurs on a larger scale usually
closes systems
define the atmosphere
a mixture of transparent gases held to the earth by gravitational forces
define the hydrosphere
a continuous layer of water at or near the earths surface which includes all liquids and frozen surface water etc
define the lithosphere
the crust and the upper most mantle, consisting of the hard and ridgid outer layer of the earth
define the biosphere
the total sum of all living matter, the biological components of the earths systems
what are the links between the lithosphere and the coastal system
tectonic plates moving may cause tsunamis or larger breaking waves
could create landforms
rock types and permeability
what are the links between the hydrosphere and the coastal system
water on the surface transports sediment like fluvial sediment from rivers etc
the seas and their tides
describe the links between the coast and the atmosphere
impacts weather and climate which impacts:
precipitation impacts how much weathering
wind impacts wave height etc
temperature can affect chemical weathering and physical etc
what are the four subsystems on earth
atmosphere
biosphere
lithosphere
hydrosphere
what links is there between the coast and the biosphere
plants- pioneer species grow on sand dunes and salt marshes etc
