Rivers and coasts 1

  1. 1. Rivers and coastsStarter activity:
  2. 2. Rivers and coasts• Learning objectives: – All to know key terms of the advanced hydrological cycle – Most to be able to separate terms into stores and flows, inputs and outputs – Some to start to link the hydrological cycle to how it might affect people and their lives• Key terms/literacy focus today: Hydrological key terms• Your starter questions?
  3. 3. The Hydrological cycle Why should we bother learning about this? Let’s see at the end of the lesson.
  4. 4. Key term Definition Key term DefinitionEvaporation Water slowly seeping Precipitation Water moves towards into the bedrock the sea through rivers and streamsGroundwater flow The movement of water Channel flow Water soaks into the soil over the surface of the layer groundPercolation Water falling from the Infiltration The very slow sky as rain, hail, sleet movement of water and snow through the bedrockEvapotranspiration Precipitation is Overland flow Water evaporates from prevented from reaching the leaves of plants back the ground by leaves into the atmosphereThroughflow Water changes state Interception Water moving through from a liquid to a gas the soil layerCondensation Water changes state With a partner, match up the from a gas to a liquid definition to the key term on your
  5. 5. The hydrological cycleIn pairs, allocate the correct key terms and definitions to each letter on your printed copy of the diagram to fully describe and explain the hydrological cycle
  6. 6. The Hydrological Cycle• Extension – colour code and label extra areas on your diagram labels to show the following: – Inputs to the hydrological cycle/system – Outputs from the hydrological cycle/system – Stores where water resides for significant amounts of time – Flows where water moves between stores
  7. 7. How could this affect humans?• Linking back to slide 3, let’s start to think about how this could affect people (and therefore why we bother studying it).• Examine your diagram. Identify areas where you think people’s lives could be affected & add an annotation to explain how this could work. Example?
