Earth Science Concepts and Principles

The video introduces Earth Science, covering its main disciplines: geology, oceanography, meteorology, and astronomy. It explains the scientific method, emphasizing hypothesis testing and theory development. The video discusses Earth's scale, time, and the nebular theory of solar system formation. It highlights the interaction of Earth's spheres—atmosphere, hydrosphere, biosphere, and geosphere—and the importance of viewing Earth as a system. The impact of natural processes on humans, such as natural disasters and climate change, is also explored.
