Why does all the water in our earth does not evaporates?

Not all the water on Earth evaporates due to a combination of factors, including temperature, atmospheric pressure, and the presence of various ecosystems that regulate moisture. The Earth's water cycle involves processes like evaporation, condensation, and precipitation, which maintain a balance. Additionally, bodies of water, soil, and vegetation help retain moisture, preventing complete evaporation. The gravitational pull of the Earth also plays a role in keeping water in its various forms on the planet.
