In: Physics Share Facebook 2 Answers Voted Bbykttn626 Added an answer on July 17, 2019 at 7:17 am Grass is a another theory. Since I live in tornado alley (Oklahoma), I can say that it’s not the craziest thing to believe either. The winds can be brutal and it will pick up anything and everything it can. I’ve seen trampolines flung over fences, birds knocked out of the air, and a bunch of other crazy shit because of the wind alone. And that’s not even during a tornado. Those are worse. So with the grass being so light, it gets pretty high up there and there’s so much that it causes a green tint. Again, it’s just a theory but I think it’s definitely a high possibility. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Whatawaist Added an answer on July 17, 2019 at 1:51 am Tornadoes typically happen around very tall storm clouds, which scatter light and make the sky mostly blue, and they typically happen later in the day with the sky tinted yellow/red from the sunset. You mix the deep blue with the yellow red and you get a greenish sky 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse What is the capital of UK?
