What is an open system?
An area where the hydrological systems drains into a main river
The water found in the cracks and spaces in soil
A system that has inputs, processes and outputs
The movement of water into the soil surface.
What are closed systems?
A continual circulation, there is a definite amount of water in the system and that this amount does not change.
Water lost from the drainage basin system
Downhill movement of water in rivers
The water found in the cracks and spaces in soil, sand and rock. It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers.
Inputs is...
A freshwater stream that feeds into a larger stream, river or other body of water
The place where the river enters the ocean
Circulation of water over the land or under the grounds surface that make water move within the river basin
Water that enters a drainage basin system
Outputs are...
The movement of water into the soil surface
Water lost from the drainage basin system
The combined loss of evaporation and transpiration
The upper layer of water stored underground
What is a River Drainage Basin System?
All rivers receive a water supply from a drainage basin system
Downhill movement of water in rivers
The upper layer of water stored underground
When the river is divided and separated into different river flows
What is a River´s Source?
A watershed
Water that enters a drainage basin system
The place where a river starts
A store
River´s mouth?
The part of a river that connects/intercepts with the ocean
Where the river separates into three.
A supply of water
An aquifer
What is a tributarie?
A process of the hydrological cycle
A part of streamflow that has infiltrated the ground
A freshwater stream that feeds into a larger stream, river or other body of water.
When the river is divided and separated into different river flows.
What happen´s in a CONFLUENCE river?
When the river is divided and separated into different river flows.
Downhill movement of water in rivers.
When the river floods
The water is lost from the drainage basin system
What is an overland flow (surface runoff)?
A huge amount of water in a specific area
The water that stays in the soil
The movement of water over the land, downslope toward a surface water body.
Water that infiltrates into the soil
Channel flow referrs to...
An area where the hydrological systems occur
The movement of water into the soil
A downhill movement of water in rivers
A part of steamflow that has infiltrated in the ground
What is the groundwater?
Water from rain
The precipitation that is collected and stored by vegetation
The upper layer of water stored underground
The water found in the cracks and spaces in soil, sand and rock
What is Groundwater flow?
Continual circulation, this means that there is a definite amount of water in the system and that this amount does not change
A part of streamflow that has infiltrated the ground, and has been discharge into a stream channel, or springs and seepage water
Higher ridge of land, the boundary between one drainage basin and another
When the river is divided and separated into different river flows
The movement of water that is found in the subsurface of the soil
Precipitation
Percolation
Infiltration
Evaporation
The precipitation that is collected and stored by vegetation
Evaporation
Water Table
Interception
Percolation
When water is heated by the sun (in the case of the water cycle), it turns into vapour
Infiltration
Evapotranspiration
Transpiration
Evaporation
The combined loss of evaporation and transpiration
Evaporation
Transpiration
Evapotranspiration
Evatranspiration
Which of the following is a river landform found in the lower course?

Abrasion
Attrition
Solution
Hydraulic action
In which section of the river do waterfalls form?
Upper course
Middle course
Lower course
Every course
For a waterfall to form there needs to be two layers of rock. Which way round must they be?
Soft rock on top of hard rock
Hard rock on top of soft rock
Below are listed the 4 types of erosion. Which two are important in the formation of waterfalls?
Hydraulic action
Abrasion
Attrition
Solution
What is this man standing in?
Undercut
Overhang
Plunge pool
Gorge
Over time the top rock sticks out over the bottom rock. It is unsupported and so eventually (a) into the plunge pool
Waterfalls are landforms created by....
Erosion
Deposition
The waterfall retreats (moves back) upstream towards the rivers source over thousands of years leaving behind a steep sided (a)
When the roots of plants grow in the cracks of a rock and splits it, we call it...

deposition
attrition
abrasion (sandpaper action)
heavy material is rolled along the river bed
Suspension
Traction
Deposition
Solution
the movement of material downstream. The bigger the material the more energy the river needs to carry it
