35
Q

The lithosphere is the…and… which constitutes (makes up) the hard and rigid outer layer of the earth and the layer is split into a number of tectonic plates

36
Q

Systems can be described in 3 ways: …, … and…

A

Open, closed, isolated

37
Q

A domestic central heating system is an example of a… system

38
Q

A domestic water supply is an example of a… system

A

Open

(Water is input through pipe from mains water supply and is output through drains)

39
Q

A closed system is a system in which…

A

Amount of matter remains constant, but in which energy can be transferred as an input, output or flow

40
Q

An open system is a system in which…

A

Energy and matter can be transferred in, through and out of beyond the boundary of the system

(In a closed system only energy can be transferred in, through and out behind the boundary of the system but matter can only be transferred through and not in or out)

41
Q

Input of system meaning

A

Energy/ matter entering system

42
Q

Output of system meaning

A

Energy and/ or matter leaving a system

43
Q

Store/ component of system meaning

A

Section of system in which matter can remain, be added to or removed from

44
Q

Flow/ transfer of system meaning

A

Movements between stores/ components in a system

45
Q

Boundary of system meaning

A

Edge of system

46
Q

The component/ store is a section of system in which …. can remain, be added to or removed from

47
Q

Flow/ transfer is movements between …. / …. in a system

A

Stores
Components

48
Q

A closed system is a system in which the amount of…. remains constant but in which energy can be transferred as an input, output or flow

49
Q

A closed system is a system in which the amount of matter remains constant but…

A

Energy can be transferred as an input/ output/ flow

50
Q

Dynamic equilibrium is where …..are equal and the stores remain the same

A

Inputs and outputs in a system

51
Q

Dynamic equilibrium in a system is where the inputs and outputs are…and stores remain..

A

Balanced
The same

52
Q

Negative feedback definition

A

A system acts by lessening the effect of the original change and ultimately reversing it

53
Q

Positive feedback definition

A

Positive feedback occurs within a system where a change causes a further snowball effect which continues or accelerates the original change so that the effects are amplified

54
Q

True or false, when the system is in balance it causes negative/ positive feedback

A

False
It causes negative/ positive feedback when the system isn’t in balance

55
Q

8 different types of factors influencing coastal landforms

A

Tectonics
Geology
Marine factors
Biotic factors
Geomorphic factors
Climatic factors
Human factors
Subaerial factors

56
Q

Negative feedback is where the system acts by lessening the…and ultimately reversing it

A

57
Q

Positive feedback in a system is where when there is a change it causes a…effect which then …the original change and makes the …amplified

A

Snowball
