Explain a process that affects people regularly in the Bay Area and across the U.S.

Discuss anything focused on the Earth Sciences as part of this assignment. However, be aware that pure biological science posts that do not have an Earth Science focus, including marine biology posts and COVID-19 posts are considered off-topic and will not count for credit. This is because you are taking a physical science and not a biological science course. A good rule of thumb is if you are tempted to title your discussion something regarding a life form or a virus, it’s probably not going to get credit for you in the discussion. However, you can always check with me before posting if you want to make sure your new topic will count for credit. Also note that replies to off-topic posts will also not count for credit regardless of focus, so be sure to avoid these threads if they are present.What criteria is used to grade this assignment?Please click the link below:”Discussion Guidelines & Rubric”Note that I recommend posting at least three times during the week in such a way that follows the rubric document above. There is no minimum or maximum word count, BUT your post should be thoughtful enough that I can grade you adequately on the physical science content of your post. See rubric document above for details.This weeks topic will cover a process that affects us regularly here in the Bay Area and across the U.S. The weather changes that you watch your local weatherperson forecast for any given week on the news is largely due to weather fronts. In the winter, these fronts (especially cold fronts) affect California by bringing rain to the region when the air is moist enough. In the Summer, the changes from warm patterns to cooler patterns are what signify that a front has moved through. This week, you will learn much of the details surrounding these changes. Please write two kinds of writing each page( two topics)
