SC200 Unit 5 Discussion Equilibrium in Natural Systems
Topic 1: Equilibrium in Natural Systems
When pressures and temperatures become unbalanced in Earth’s atmosphere, it can produce some dramatic effects as the system tries to rebalance itself or re-equilibrate (reach equilibrium). Many of these changes are things that are witnessed every day on a small scale in the form of weather, such as wind, rain, snow, fog, etc.
Sometimes, however, Earth’s atmosphere experiences very large imbalances which can cause massive and very disruptive change. The extreme weather events of the past decade are good examples of extreme changes that required re-balancing (equilibration). Not only did they have environmental impacts, but also disastrous consequences for the hundreds and thousands of people in their wake.
Review the Discussion resources.
Then, during the week, discuss with your classmates:
- What kinds of natural imbalances might affect your region? What makes your region particularly vulnerable to these imbalances?
- Provide a specific example of a weather incident/natural disaster that occurred in your area in the past and discuss how the incident was handled by local residents and town/state officials.
- What can people in your area do to prepare for a similar incident? Consider what can be done prior to, during, and after the disaster (be sure to include specific details using information from the CDC and/or FEMA).
- Compare your area to that of a classmate. What environmental features do you have in common to produce similar natural disasters OR what features vary, leading to completely different disasters? Would rescue efforts differ as well?
- What predictions are being made for how climate change will impact either the frequency or intensity of future natural disasters in your area? (Hint: refer to the extreme weather and hurricane resources provided above to find information to support your ideas).
Review the Discussion guidelines.

SC200 Unit 5 Discussion Equilibrium in Natural Systems Answer
The three types of natural disaster that South Carolina is most likely to be impacted by are earthquakes, hurricanes, and tornados. The effects of these disasters are floods, fire, dam failures and severe thunderstorms (SCEMD). The reason that Greenville is particularly vulnerable to these imbalances are due to the warmth from the hot summers and short winter storms that move in from the coastline and moist air moving north from the Gulf of Mexico (GCTH). The Upstate Carolina is extremely close to the Atlantic Coastal Plain and receives a lot of the aftermath when hurricanes and tornadoes hit shorelines…….
