Construct scientific arguments to support claims that the physical conditions of Earth enable the planet to support carbon-based life.
- Earth’s Paleobiosphere
The student will demonstrate an understanding of the dynamic relationship between Earth’s conditions over geologic time and the diversity of organisms.
Living things have changed the makeup of Earth’s geosphere, hydrosphere, and atmosphere over geological time. Organisms ranging from bacteria to human beings may contribute to the global carbon cycle. They may influence the global climate by modifying the chemical makeup of the atmosphere. As Earth changes, life on Earth adapts and evolves to those changes. Just as life influences components of the Earth System, changes in the Earth System influences life.
