Earth's Systems and Their Interactions

The video tutorial discusses Earth's systems: atmosphere, biosphere, geosphere, and hydrosphere. It explains their components and how they interact and depend on each other. Examples include tornadoes affecting the biosphere, pollution from factories impacting the atmosphere, and mudslides caused by rain altering the geosphere. The Grand Canyon is highlighted as a result of hydrosphere-geosphere interaction. The video also covers biosphere interactions, such as deforestation increasing CO2 levels, contributing to global warming. The tutorial emphasizes the interdependence of these systems.

Which of the following is NOT a component of the geosphere?
