1. What is the hydrological cycle? Key Theme: Rivers Precipitation Condensation Surface Runoff Transpiration Infiltration Throughflow Evaporation Groundwater Flow

2. What is the river system? Key Theme: Rivers Are these inputs, stores, transfers or outputs? Precipitation Transpiration Sea Interception Evaporation Lake Surface Runoff Infiltration Throughflow Groundwater storage Soil moisture storage

3. What is a drainage basin? Watershed: Watershed: The higher outer boundary between two drainage basin Mouth: Mouth: where the river enters the sea Tributary: Tributary: a smaller stream or river that flows into a larger stream or river Confluence: Confluence: where two or more steams or rivers meet Floodplain: Floodplain: a flat area either side of the river that floods Source: Source: the point where a river begins Estuary: Estuary: an area of tidal water just before the mouth Key Theme: Rivers

4. Catchment The area from which water drains into a particular drainage basin. Tributary A river which joins a larger river. Confluence The point at which two rivers join. Watershed The boundary dividing one drainage basin from another- a ridge of high land. Source The upland area where the river begins. Mouth Where the river flows into the sea, or sometimes a lake. Key Theme: Rivers

5. Mark and locate on the map: watershed, confluence, source, tributary AND add a key. Key Theme: Rivers

6. Which three processes shape a river? Erosion Abrasion Attrition Hydraulic Action Solution Key Theme: Rivers Sheer force of the water forcing cracks in the banks open Chemical reactions cause the rocks to break down Fragments of rock hit the bed and banks and cause it to wear away Pebbles and rocks collide with each other causing them to reduce in size

7. Which three processes shape a river? Transportation Traction Suspension Solution Saltation Key Theme: Rivers Minerals dissolved in the water Big boulders and stones rolled along the river bed Small stones and pebbles bounced along the river bed Very small particles are carried along suspended in the river

8. What fluvial landforms have we studied? Key Theme: Rivers
