What observations and inferences from fossils might have been used to build the computer model

when scientists figure out what is in a fossil dinosaur dropping, they can then make inferences about what the dinosaur ate when it was alive. They are not observing the dinosaur eating—they are using evidence to make an inference.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
