Believe it or not, 99.9% of the species on Earth have gone extinct. Now, not all of these were caused by Humans, some were caused by MAJOR cataclysmic events such as the extinction of dinosaurs or other prehistoric animals that make up a large amount of the species on Earth.

Hope this helps, if not, comment below please!!!
“Remember, we are ultimately trying to explain how hailstorms form. We now know the air is colder higher up in the atmosphere than it is near the ground, which helps us understand where it might be cold enough for hailstones to form.
Our next step is to figure out why the air up high is colder. Based on what we have figured out from the weather balloon data, if we gathered more data by moving closer to the ground, what do you think we would see in that data?
In addition, if we looked at weather balloon data taken at 12:00 noon instead of 12:00 midnight, what do you think we would see in that data?
Do you think we would see the same patterns? Why or why not?” Hope this helps if not write in the comments maybe I will be able to find other answers that might help you. If helped mark me the brainiest!! THESE ARE QUOTES DO NOT COPY ITS IS PLAGIARISM!!
