The Sun
  • In this chapter we will talk about
  • The Role of the Sun
  • Effect on Weather
  • The snug Earth
  • Solar Power
  • Why do we have temperature
  • How do we measure air temperature?

The Suns Role
  • The Sun is the ultimate source of heat energy of
    the earth.
  • All the Earths heat and light comes from the Sun.

Life Support
  • The Sun keeps the temperature of most of the
    Earths surface at 51 to 49 degrees Celsius.
  • For most living things can only survive at 0 to
    49 degrees Celsius.
  • If the amount of sunlight reaching the Earth was
    cut by one tenth, the oceans would turn to ice
    and like on Earth would die.

Effect on Weather
  • The Sun is the key to the worlds weather.
  • Its rays filter through the atmosphere and warm
    the Earths surface which heats the air above.
    This makes the air move because warm air rises.
  • The movement of air causes winds which lead to
    weather changes.

The Snug Earth
  • The Earth absorbs sunlight and then releases it
    into the air again as heat.
  • The heat is trapped by water vapour and clouds in
    the atmosphere and reflected back to Earth.
  • The atmosphere acts like an enormous blanket
    around the Earth, keeping the warmth.

Solar Power
  • Solar panels are used to collect the Suns heat.
  • Water in them absorbs the heat and is used to
    warm homes. Electricity can also be made from

Why do we have air temperature?
  • Air temperature tells us how hot or how cold the
    air is.
  • This greatly affects the weather.
  • It is important to us because we need to wear
    different clothes for different temperature.

How do we measure air temperature?
  • Thermometers are used to measure air temperature.
  • They are placed in the shade, 1.5m off the
  • That is because in direct sunshine and on the
    ground, temperature recorded maybe much higher
    than that off the ground.
  • Air temperature is measured in degrees Celsius
    (C) or degrees Fahrenheit (F)
