The true statement about ‘green house effect’ is that it is a) caused by combination of many gases I saw the filled balloons tip the balance in the last science class. And the combined weight of these molecules causes a pressure pressing down on your body of 10,000 kg per square metre (10,000 kg = 22,000 lbs). Asking a human if air is heavy is like asking a fish if water is heavy. Take a plastic pop bottle and with the cap off the bottle, hold you hand above the mouth of the bottle and squeeze.Â What do you feel?Â Screw the cap on tightly and squeeze again.Â What happens when you squeeze the bottle now?Â Now, fill the bottle completely with water, replace the cap and squeeze again.Â What do you feel now?
