A high-pressure weather system. Average sealevel pressure at the centre of the system is usually above 1000 mbar. It brings stable weather

Question 5

Aquifer

Answer 5

And underground lake, that will still water. The water found here can be abstracted from the rock by drilling boreholes

Question 6

Attrition

Answer 6

When the pebbles that are transported by a river or along the coast knocked together and become smaller, more rounded and smoother. Like when you play conkers at primary school

Question 7

Backwash

Answer 7

The movement of material back of a beach

Question 8

Bankfull stage

Answer 8

The discharge above which the river will be on able to hold all of the water so it floods

Question 9

Base flow

Answer 9

The normal level of water within a river

Question 10

Beach nourishment

Answer 10

A coastal management technique, whereby pebbles (sediment) are moved into areas that need nourishing, due to loss of pebbles (sediment) by Longshore drift

Question 11

Channelisation

Answer 11

Strengthening of the river’s bands to make the river flow move quicker through the area and reduce the risk of flooding

Question 12

Channel (river)

Answer 12

The area in which a river travels in

Question 13

Climate

Answer 13

The average weather conditions measured over a 30 year period

Question 14

Climatic region

Answer 14

A large area which experience is the same or similar climatic conditions

Question 15

Closed system

Answer 15

A system which does not have any input or output and is closed to its surroundings

Question 16

Condensation

Answer 16

The process by which water turns from a gas to a liquid form

Question 17

Dumbs

Answer 17

Large scale hard engineering management features seen in rivers

Question 18

Deforestation

Answer 18

Theremoval of trees in an area

Question 19

Deposition

Answer 19

The dropping of material in a river or at the coast

Question 20

Depression

Answer 20

A low pressure weather system found in the mid latitudes of the northern hemisphere where tropical warm air mass pushes into an Arctic cold air mass. Warm air rises to give low-pressure; this is usually less than 1000 mbar. Brings on stable weather

Question 21

Discharge

Answer 21

The volume of water flowing down a river at any given time, measured in cubic metres per second-CUMECS

Question 22

Drainage basin/catchment area

Answer 22

An area of land which a river collects all of its water from

Question 23

Drought

Answer 23

I prolonged period of whether, when you receive less than the average rainfall

Question 24

Erosion

Answer 24

The breaking down of material in a river or at the coast

Question 25

Evaporation

Answer 25

The process by which water tones from a liquid into a gas

Question 26

Falling limb

Answer 26

The decrease in discharge line, shown on a flood hydrograph

Question 27

Flood

Answer 27

When a river has more than average amount of precipitation, causing water to flow over an area that is usually dry

Question 28

Flood plain

Answer 28

The stretch of relatively flat land on the sides of the river. It is usually covered by fertile flood deposits called alluvium

Question 29

Flow

Answer 29

The transfer of water between stores this could be in the same state or involve a change in state

Question 30

Front

Answer 30

The Boundry at which hot and cold air meet

Question 31

Gabions

Answer 31

A coastal management technique, whereby pebbles are put into wire mesh cages to slow the rate the rate of erosion

Question 32

Geology

Answer 32

The rock type of an area

Question 33

Global hydrological cycle

Answer 33

A closed system, where water is continuously moved around the worlds lithosphere; hydrosphere and atmosphere

Question 34

Global warming

Answer 34

A geographical theory that simply says that the Earth's average surface temperature is getting warmer

Question 35

Ground flow water

Answer 35

Water that is stored and flows on the ground in permeable rocks

Question 36

Groynes

Answer 36

A coastal management technique, whereby man-made barriers are built to slow the rate of longshore drift

Question 37

Hard engineering

Answer 37

When a coastal management technique is made from concrete or man-made materials

Question 38

Hydraulic action

Answer 38

The. The water hits the bed and banks of the river or coastline causing sections to break away. Like a jet washer being used to clean mud off of a car

Question 39

Hydroelectric power

Answer 39

Electricity generated by water flowing through turbines

Question 40

Hydrological cycle

Answer 40

An open system, where water is recycled through the land; sea and air. It can go into the system and out of the system at any time

Question 41

Hydrosphere

Answer 41

All the stores and flows of water and it's gas; liquid and solid states

Question 42

Infiltration

Answer 42

The movement of water from surface down into the soil

Question 43

Impermeable

Answer 43

Rocks that do not allow water to pass through them. The opposite of permeable which are rocks that do allow water to pass through them

Question 44

Input

Answer 44

Material which is putting all taken into a system. Water as precipitation is the input to a drainage basin

Question 45

Interception

Answer 45

When water is prevented from falling directly to the ground

Question 46

International

Answer 46

When something occurs across a country's national boundaries

Question 47

Abrasion/corrasion

Answer 47

Where pebbles that are carried along a river or coastline scrape the bank and bed wearing it down. Like when you use sandpaper to rubdown a piece of wood in design and technology
