I am teaching a secondary school course on my state's local history. The textbook begins with the history of the first humans, yet I think it is unfair not to start back much earlier, introducing the geologic history.
Students finished a lesson on the slow changes that took place over the past 4.5 billion years on Earth, gradually leading to the formation of our state. I want the students to understand these changes haven't stopped, just we maybe can't see everything happening, as it happens slowly.
A later lesson will focus on human changes, but I want to first cover natural changes:
- Earth's magnetic pole is moving.
- Moon slowly getting further away.
- Days are slowly getting longer.
- Tectonic plate slowly moving 1 inch west-southwest.
- Wind and rain slowly shaping landscape.
Without having a geology background, I'm quite concerned I overlooked some important changes. There are some locally specific features I identified (such as a slowly-splitting rift valley), but are there any other major changes I ought to include?
