Why is the earth capable of substaining all three forms of water?

Earth can sustain all three forms of water—solid (ice), liquid (water), and gas (water vapor)—due to its unique distance from the Sun, which allows for a suitable range of temperatures. This range enables water to exist in different states depending on environmental conditions. Additionally, the presence of atmospheric pressure plays a crucial role in determining the state of water, allowing it to transition between ice, liquid, and vapor. The planet's diverse ecosystems and climates further contribute to these varying states of water.
