There are “Big Ideas” and supporting concepts that all Americans should know about Earth sciences. These are laid out in a new guide published by the Earth Science Literacy Project and the National Science Foundation.
Here's a short list of the Big Ideas, some of which challenge political agendas:
BIG IDEA 1. Earth scientists use repeatable observations and
testable ideas to understand and explain our planet.
BIG IDEA 2. Earth is 4.6 billion years old.
BIG IDEA 3. Earth is a complex system of interacting rock, water, air, and life.
BIG IDEA 4. Earth is continuously changing.
BIG IDEA 5. Earth is the water planet.
BIG IDEA 6. Life evolves on a dynamic Earth and continuously modifies Earth.
BIG IDEA 7. Humans depend on Earth for resources.
BIG IDEA 8. Natural hazards pose risks to humans.
BIG IDEA 9. Humans significantly alter the Earth.
