Flashcards in Physical Key Words Deck (54):
1

Destructive Plate Boundary

oceanic and continental move towards each other - oceanic falls below continental

2

Constructive Plate Boundary

two continental plates move apart - volcano through middle

3

Collision Plate Boundary

two continental plates moving towards each other - fold up making mountain

4

Conservative Plate Boundary

oceanic and continental move past each other - oceanic quicker

5

Economic

how it affects the economy

6

Social

how it affects people

7

Environmental

how it affects the environment

8

Preparation

being ready for something - e.g. training

9

Mitigation

reducing the impact

10

Air masses

how different weather is created

11

Convectional

convectional thunderstorm

12

Ecosystem

natural system of plants, animals and the environment

13

Biome

large collection of ecosystems e.g. rainforest

14

Nutrient cycle

less trees = less nutrients as less leaves decomposing

15

Permafrost

permanently frozen ground

16

Sustainability

benefit the present but don’t affect future needs

17

Biodiversity

variety of life in an area

18

Producers

organisms that absorb energy from plants through photosynthesis

19

Consumers

eat producers

20

Constructive Wave

swash stronger than backwash - beaches

21

Destructive Wave

backwash stronger than swash - erosion

22

Fetch

distance over which the wind has blown

23

Moraine

large rock material transported than deposited by ice

Recessional, Terminal , Lateral, Ground, Medial

24

Drumlin

egg shaped hill - shaped by moving ice

25

Erratic

boulder in middle of nowhere

26

Suspension

particles suspended in water (2)

27

Traction

large pebbles roll along seabed (4)

28

Saltation

hopping motion of particles too heavy to be suspended (3)

29

Solution

dissolved chemicals in water (1)

30

Rotational Slip

soil particles expand and contract causing movement

31

Rockfall

rock falls away from freeze-thaw

32

Landslide

heavy rock slides downhill quickly

33

Mudflow

not enough vegetation so soil is loose and breaks away

34

Hydraulic Power

sheer power of wave forces air into cracks, breaking rock

35

Attrition

rocks grind against each other - smaller and more rounded

36

Abrasion

sandpaper effect of pebbles grinding over surface - smooth

37

Solution

dissolved chemicals dissolve surface

38

Corrasion

hurling rocks at cliff

39

Arête

sharp mountain ridge

40

Ribbon Lake

lake found at bottom of glacier - trough

41

Corrie

hole in mountain

43

Till

material left behind

44

Plucking

jagged rocky surface from glacier moving on top

45

Spit

caused from LSD moving sediment up the beach

46

Tropical storm

area of low pressure with temperatures of over 27*c

47

Commercial farming

farming to sell produce for profit

48

Biodiversity

variety of life in an area

49

Bar

when a spit grows across the bay, enclosing it

50

Beach nourishment

addition of material to beach

51

Dune regeneration

replanting of grass to strengthen dune

52

Gabion

steel wire cage filled with boulders

53

Types of glacial erosion

Abrasion
