A: The warm updraft heats air molecules to extreme temp
B: Positive and Negative ions build up and need to discharge
C: High pressure storms condense air into a high energy state

The snorkeling guide made one fact very clear- these colonies of tiny organisms would not last. In fact, wed be lucky if they lasted 5 more years. She cared about the safety of these coral reefs more than she has cared about anything for a long, long time. She had to do something for the fragile, endangered habitat with its fish, mollusks, worms, crustaceans and many more.So, she used her money to create a lab at her aunts house. She worked tirelesslyendlesslysleeping only when she had to. Its what mom and dad would have done, she thought.Her best friend Sam, would hang out with her everydayeating pizza, fries, and whatever else he could get his hands on, keeping her company with his humor while Sophie worked on her experiments. And now, she has a biological solution in her hands. She hesitated at the door to the labs. Nervously, she shifted her lab report from one hand to the other. I know that have an innovative approach to solving the coral reef issue and I know I can help, she said to no one. The image of being ridiculed by these professors, delayed her entry. She stood outside the door, wanting to run back- wanting to hide- glued to the icy spot.Hey, Sophie! She turned at the unexpected sound of Sams voice. Ive been trying to catch up with you, he panted- out of breath. Lets go in and show them what youve got. Sophie tilted her head, smiled at Sam and opened the door.
