Dry Earth (āĻļā§āĻāĻžāĻ¨ āĻĒā§āĻĨāĻŋā§ąā§)
If all water disappeared from Earth, the planet would become completely dry and lifeless. Rivers, lakes, seas, and oceans would disappear, and the water cycle would stop because there would be no evaporation or rainfall.
Plants, animals, and humans cannot survive without water, so all living things would be greatly affected. Without clouds and rain, the atmosphere would become hotter and the climate would turn extreme. Earth would lose its natural balance and life would become impossible.

What If All Water Disappeared from Earth ?
If all water disappeared from Earth, the planet would become completely dry. Rivers, lakes, and oceans would vanish, and the water cycle would stop. Since all living organisms depend on water, plants, animals, and humans would not survive. The atmosphere would change, with no clouds and rising temperatures, making the climate extreme. Thus, life on Earth would become impossible.
