Question 1

what are the basic components of a system

Answer 1

inputs, outputs, processes/transfers, stores

Question 2

what are some examples of inputs at the coast

Answer 2

energy from waves, wind, tides, currents
sediment
sea level change

Question 3

what are some examples of transfers/processes

Answer 3

erosional processes, wind and water transport

Question 4

what are some stores at the coast

Answer 4

erosional landforms and landscaped
depositional landforms and landscaped

Question 5

what are some outputs at the coast

Answer 5

dissipation of wave energy
sediment removed beyond the sediment cell

Question 6

what is our example of a low energy coastline

Answer 6

Chichester Harbour

Question 7

what is a closed system

Answer 7

where energy is transferred across the system boundary but no matter is transferred

Question 8

is the carbon cycle an open or closed system and why

Answer 8

closed, because all elements circulate so no matter passes out or in the system

Question 9

is the global water cycle open and closed and why

Answer 9

closed because the planet doesn’t loose or gain water

Question 10

is a river drainage system open or closed and why

Answer 10

open, because it has inputs and outputs of precipitation and outputs of water at the river mouth

Question 11

what three kinds of properties do we find within the boundary of a system

Answer 11

elements
attributes
relationships

Question 12

what are elements

Answer 12

the parts that make up a system

Question 13

what are attributes

Answer 13

characteristics of the elements, for example quantity, size or volume etc

Question 14

what are relationships

Answer 14

the associations that occur between elements and attributes

Question 15

which system occurs on a larger scale usually

Answer 15

closes systems

Question 16

define the atmosphere

Answer 16

a mixture of transparent gases held to the earth by gravitational forces

Question 17

define the hydrosphere

Answer 17

a continuous layer of water at or near the earths surface which includes all liquids and frozen surface water etc

Question 18

define the lithosphere

Answer 18

the crust and the upper most mantle, consisting of the hard and ridgid outer layer of the earth

Question 19

define the biosphere

Answer 19

the total sum of all living matter, the biological components of the earths systems

Question 20

what are the links between the lithosphere and the coastal system

Answer 20

tectonic plates moving may cause tsunamis or larger breaking waves
could create landforms
rock types and permeability

Question 21

what are the links between the hydrosphere and the coastal system

Answer 21

water on the surface transports sediment like fluvial sediment from rivers etc
the seas and their tides

Question 22

describe the links between the coast and the atmosphere

Answer 22

impacts weather and climate which impacts:
precipitation impacts how much weathering
wind impacts wave height etc
temperature can affect chemical weathering and physical etc

Question 23

what are the four subsystems on earth

Answer 23

atmosphere
biosphere
lithosphere
hydrosphere

Question 24

what links is there between the coast and the biosphere

Answer 24

plants- pioneer species grow on sand dunes and salt marshes etc

Question 25

what is dynamic equilibrium

Answer 25

when there is a balance between the inputs and outputs so the system is in equilibrium, it stays the same

Question 26

what is an example of dynamic equilibrium at the coast

Answer 26

the rate of sediment leaving the beach is the same as what’s being deposited

Question 27

define positive feedback

Answer 27

increases the effect of a change and moves the system away from balance or dynamic equilibrium

Question 28

define negative feedback

Answer 28

this helps reduce the impact of change, which brings the state closer to dynamic equilibrium

Question 29

what does coastlines being dynamic locations mean

Answer 29

they are constantly changing
