Planet Earth is the result of years of evolution. And for us to be able to live and interact with other human beings, animals and other species, it was necessary that the living conditions were sustainable on the earth's surface.
This means that the air had to go through several transformations to receive the quality of “breathable air” or air that provides life for all inhabitants of the planet. After all, in the early days of Earth, the air was not composed of a very important gas.
Over the years, atmospheric air has acquired greater complexity, due to the presence of some gases that, combined, make our existence possible.
And today, your challenge is to discover which gases are fundamental for life on planet Earth. In the image below, you can see a hangman game and some letters are already filled in, to give you a hint on how to get started.
So now it's time to get your hands dirty and respond. The ideal is to play with someone else, so they can see the answer and help you fill in the doll on the gallows, if applicable.
Challenge: There are 3 words on the gallows
In the game of hangman, the ideal is that the dummy of the hangman is not filled. If it is fully drawn, it means you misspelled the word. Today, its mission is to fill in which gases are responsible for maintaining life on Earth.
Below you can see some more tips, so if you still need a boost, drag the screen down a little.
Two of them are present in great abundance and are the main gases. Their proportions are at 78% and 21%. The other, with lesser participation, but still essential for balance, is responsible for only 0.09% of atmospheric air.
If you still don't know what these gases are, you can check the answers below. The tip is: Look only after trying to answer all the words.
