THE GREENHOUSE EFFECT
DO NOW TASK
MAKE ANY IMPROVEMENTS IN PURPLE
WHY IS OUR ATMOSPHERE IMPORTANT?
• It helps to maintain a consistent temperature
• Without the atmosphere it would be about -118C all the time!
• It acts as a shield, protecting the Earth from harmful radiation
• It provides the correct environment for the
water cycle
• Water exists on Earth in all 3 states
• It enables our weather systems and provides
for all our ecosystems
OUR ATMOSPHERE
THE GREENHOUSE EFFECT
These 3 conditions are needed to maintain life on Earth.
They create the ‘Greenhouse effect’.
ANSWER THE QUESTIONS IN YOUR
BOOK
HOW DID YOU DO?
WHAT CAUSES THE GREENHOUSE
EFFECT?
• https://youtu.be/SN5DnOHQmE
• Watch the video
• Draw the diagram in your
book
• The sun gives out all forms of radiation.
• Some are stopped by the atmosphere and some are
allowed through to the Earth.
• Earth absorbs energy from the sun.
• Earth re-emits radiation as heat.
• A small amount passes back through the atmosphere
but a lot gets trapped by the atmosphere and
reflected.
• This trapped infrared radiation has a warming effect
