Geography 1 - The Hydrological Cycle
- The hydrological cycle shows how water moves
around
- It has different parts - the sea, the land and the
atmosphere
- Water flows between the different parts in various ways, and is also stored on the
land
- The hydrological cycle is a closed system. This means there are no inputs or outputs - the water
just flows around the cycle

- 1. Water evaporates from the sea and the land
- Evaporation is when water is heated by the sun and turns into water vapour
- Transpiration is the evaporation of water from plants
- Evapotranspiration is both evaporation and transpiration happening together

- 2. Water vapour
- Moved inland by winds
- Moved inland by winds
- 3. Water vapour condenses
- To form clouds and then falls over the land as precipitation
- To form clouds and then falls over the land as precipitation
- 4. Water moves from one place to another in many ways (called flows or transfers)
- Infiltration - water soaks into the soil
- Percolation - water moves vertically down through the soil and rock
- Throughflow - water in the soil flows downhill
- Groundwater flow - water in rock flows downhill
- Surface runoff - water flows overground
- Channel flow - flow of water in a river
- Channel flow - flow of water in a river
- Surface runoff - water flows overground
- Groundwater flow - water in rock flows downhill
- Throughflow - water in the soil flows downhill
- Percolation - water moves vertically down through the soil and rock
- Infiltration - water soaks into the soil
- 5. Water can also be held on the land in stores
- Channel storage - water is held in a river
- Groundwater storage - water is stored underground in soil and rock. A
rock that stores water is called an aquifer, e.g. chalk
- Interception storage - water lands on things like plant leaves and doesn't hit the ground
- Surface storage - water is held in things like lakes, reservoirs and puddles

- 6. The water eventually ends up in the sea
- Where it evaporates and goes round the cycle again
- Where it evaporates and goes round the cycle again
