Your task is to watch a video about the greenhouse effect and global warming and to do exercises that are prepared on the basis of the video. You have to clik on the task and watch the video then answer the questions below:

  1. What do you associate the greenhouse effect and global warming with? Write down your ideas.
  2. Watch the video agian and decide whether the sentences are TRUE (T) or FALSE (F).

  1. Why is the Earth getting warmer?

  2. What is the main reason why the climate is changing?

  3. One effect of Global Climate change is increased temperature, how much will the temperature rise?

  4. Why is the changing of temperature a big deal? (even if it just changes a little bit)What are five changes to the planet that are most likely to happen because of the change in global climate?

CONCLUSION

Well done! Now that you have made all the exercises, you are aware of what the greenhouse effect and the global warming consist in and why they are so dangerous for our Planet.This knowledge will help you think about how you can contribute to stopping these processes and become a real hero who will save our home, the Earth, from danger.
