Exploring the Hydrosphere

The video tutorial introduces Earth's hydrosphere, comparing it with the geosphere and atmosphere. It explains the distribution of water on Earth, highlighting that 97% is salty ocean water, while only 3% is freshwater. The tutorial discusses the sources of freshwater, emphasizing groundwater's importance. It also covers the use of reference tables to understand the chemical composition of Earth's layers, providing insights into the hydrosphere, geosphere, and troposphere.
