This podcast focuses on understanding how Earth systems function, including the composition of air and the various spheres of the Earth: the ecosphere, hydrosphere, lithosphere, biosphere, and atmosphere. It explores different cycles of matter such as the carbon, oxygen, hydrogen, nitrogen, and phosphorous cycles. Additionally, the podcast examines human activities and their impact on atmospheric changes over time. Finally, it discusses the types of tectonic plate movements and their effects, considering the extent to which science can be harnessed to prevent or mitigate natural disasters.
