  • Weather and Climate
    • Rainfall
      • Relief
        • Warm, moist air travels over the sea caused by evaporation
        • Air meets a hill and rises
        • Air cools and condenses forming clouds
        • Rain falls, leaving a rain shadow on the other side of the hill where less rain falls
      • Frontal
        • A warm front and a cold front meet
        • The cold air undercuts the warm air, causing the warm air to rise
        • The warm air cools and condenses and rain falls
        • Frontal rain is the most common rain in Britain
      • Convectional
        • The sun heats water on the ground
        • The water evaporates and rises
        • The air cools and condense, clouds are formed
        • Rain falls
    • Weather is the day-to-day state of the atmosphere
      • Climate is the average weather over a long period of time in a particular place
    • Climate is the average weather over a long period of time in a particular place
    • Water Cycle
      • 1. The sun evaporates water from large masses of water
        • Water evaporated from trees is called transpiration
      • 2. Water vapour rises and cools and condenses to from clouds
      • 3. Precipitation falls as rain, snow, sleet or hail
        • Trees can intercept water
      • 4. Some water flows above ground as surface-flow
      • 5. Water may infiltrate into the ground a travel as through-flow
      • 6. Some water percolates even deeper through permeable rocks
    • Measuring weather
      • Thermometer
        • Measures temperature
      • Barometer
        • Measures air pressur
      • Anemometer
        • Measures wind speed
      • Weather vane
        • Measure wind direction
