1What are the outputs from a drainage basin system?
- ARiver mouth
- BEvaporation
- CTranspiration
- DRiver flow
- ERainfall
2[blank_start]Infiltration[blank_end] - the process by which water enters the soil
[blank_start]Percolation[blank_end] - when water moves vertically down through soil and rock
[blank_start]Throughflow[blank_end] - water in the soil flows downhill
[blank_start]Groundwater flow[blank_end] - water in rock flows downhill
[blank_start]Surface runoff[blank_end] - water flows overground
[blank_start]Channel flow[blank_end] - flow of water in a river
[blank_start]Channel storage[blank_end] - water held in a river
[blank_start]Groundwater storage[blank_end] - water stored underground in rocks and soil
[blank_start]Water table[blank_end] - upper surface of groundwater
[blank_start]Interception[blank_end] - precipitation trapped or stored temporarily on vegetation
[blank_start]Surface storage[blank_end] - precipitation stored above the ground, such as puddles, lakes and resevoirs- AInfiltration

- HGroundwater storage
- IWater table

3[blank_start]Freeze thaw[blank_end] weathering is the type of mechanical weathering that happens in [blank_start]drainage basins[blank_end].
It happens when the temperature alternates above or below [blank_start]0c[blank_end]. Water gets into the cracks in rocks, which [blank_start]expands[blank_end] when frozen, [blank_start]creating[blank_end] pressure, but [blank_start]contracts[blank_end] when thawing, [blank_start]releasing[blank_end] pressure. After repeats of this process, the cracks [blank_start]widen[blank_end] and the rocks break up.- AFreeze thaw
- BCarbonation
- CBiological
- Ddrainage basins
- Ethe sea
- F0c
- G10c
- Hexpands
- Ishrinks
- Jcreating
- Kreleasing
- Lcontracts
- Mexpands
- Nreleasing
- Ocreating
- Pwiden
- Qshrink
4Biological weathering is the breakdown of rocks by erosion
- AVerdadero
- BFalso
5What type of weathering occurs when weak carbonic acid reacts with rock that contains calcium carbonate to dissolve the rocks?
- AChemical weathering
- BBiological weathering
- CMechanical weathering
6A river's long profile shows the path of the river as it flows downhill, following a course
- AVerdadero
- BFalso
7Label the diagram
- AUpper Course
- BSteep sided, thin channel
- CMid-Course
- DDeveloping valley floor, wider channel
- ELower course
- FWide flood plains, deep channel
8Label the diagram of transportation processes
- ASuspension
- BSolution
- CTraction
- DSaltation
9Deposition occurs when the [blank_start]volume[blank_end] of water in the river falls, the river reaches it's [blank_start]mouth[blank_end], the amount of eroded material [blank_start]increases[blank_end] and the water is [blank_start]shallower[blank_end].
- Avolume
- Bmouth
- Cshallower
- Dincreases
10Waterfalls form when a river flows over an area of [blank_start]hard rock[blank_end] followed by an area of [blank_start]softer rock[blank_end]. The softer rock is eroded more, so forms a [blank_start]step[blank_end] in the river, eventually forming a waterfall. The hard rock is eventually [blank_start]undercut[blank_end] by erosion as it becomes [blank_start]unsupported[blank_end] and collapses. The collapsed rock swirls around at the bottom creating a [blank_start]plunge pool[blank_end]. As more undercutting occurs, the waterfall [blank_start]retreats[blank_end], creating a [blank_start]gorge[blank_end].
- Ahard rock

- Ddrop
- Eundercut

- GThe hills interlock
- HThe hills are individual
12Characteristics of a flood plain?
- Awide valley floor
- Bsteep sides
- Cmeanders across the land
- Dtravels in a straight direction
- Edeposition occurs
13Where is erosion more likely to occur in a river?
- AOutside of a bend
- BInside of a bend
14What is formed when erosion breaks through a river to follow the shortest course?
- AOx-Bow lake
- BDelta
- CGorge
15Label the different types of river deltas

16Levees are natural embankments along the edges of rivers

17Label the storm hydrograph

- CLag time
- DBase Flow
- EStorm Run-off
- FFalling Limb
- GPeak discharge
- HRainfall (mm)
- IRunoff / Discharge (cumecs)
18River discharge is affected by different factors. [blank_start]High rainfall[blank_end] and [blank_start]intense[blank_end] rainfall causes more runoff and a [blank_start]shorter lag[blank_end] time. [blank_start]Impermeable rock[blank_end] and previous wet conditions mean water can't [blank_start]infiltrate[blank_end] to saturated soil, so there's more [blank_start]runoff[blank_end] and shorter lag time. Low and light rainfall causes [blank_start]less[blank_end] runoff and a [blank_start]longer[blank_end] lag time, as well as [blank_start]gentle slopes[blank_end]. More vegetation means more water is [blank_start]interpreted[blank_end] and evaporates, so less water reaches the channel. [blank_start]Throughflow[blank_end] is also slowed by roots, so there's a longer lag time.
Urban areas have lots of impermeable rock, [blank_start]increasing[blank_end] discharge.
Rural areas have more vegetation, [blank_start]decreasing[blank_end] discharge.- AHigh rainfall
- Bintense
- Cshorter lag
- DImpermeable rock
- Einfiltrate

- Hlonger
- Ishorter
- Jgentle slopes
