What would happen if there isn't hydroshpere?

Without the hydrosphere, Earth would be drastically different, as it encompasses all water sources, including oceans, rivers, and groundwater. The absence of water would eliminate ecosystems, disrupt climate regulation, and make the planet inhospitable for most forms of life. Agriculture would collapse, leading to food shortages, while temperatures would soar due to the lack of water's moderating effects. Overall, the absence of the hydrosphere would result in a barren, lifeless planet.
