People and Planet

Earth is a changing and complex system of spheres; the biosphere (living things), hydrosphere (water), geosphere (land), and atmosphere (air) interact with each other to form the places and processes found on Earth. As Earthlings, we play a significant role in Earth's interactions as we both influence and are influenced by Earth's spheres; we depend on Earth's resources and are impacted by natural hazards.

This unit explores the interactions between people and the planet. How does the Earth affect you and your family? How do you and your family affect the Earth? Knowing about Earth's interactions empowers you to make informed, intelligent decisions. Knowledge is power so.....POWER ON!
