Hydrosphere: The hydrosphere is all the water on Earth, including oceans, rivers, lakes, and even the water in the air.
Biosphere: The biosphere is where all living things exist, like plants, animals, and people, and where they interact with each other and their environment.
Processes in the Hydrosphere: In the hydrosphere, processes like evaporation help turn water from oceans and lakes into vapor to form clouds, and then it falls back to Earth as rain or snow.
Processes in the Biosphere: In the biosphere, processes like photosynthesis allow plants to use sunlight to make food, which helps them grow and provides oxygen for animals and people to breathe.
