Water never disappears — it travels!
The water in your glass today is the same water the dinosaurs drank. How is that possible? Because Earth keeps its water moving in a big circle called the water cycle.
The Sun is the engine of this circle. It warms the sea, and the water rises into the sky as invisible water vapor. High up, the air is cold, so the vapor turns back into tiny drops that make clouds. When the drops grow heavy, they fall as rain or snow. The water runs back to the sea… and the journey starts again.
The four steps of the cycle
- The Sun warms the water in the sea and the water rises as invisible vapor (evaporation).
- The vapor cools high in the sky and turns into tiny drops that form clouds (condensation).
- The drops grow heavy and fall as rain or snow (precipitation).
- The water runs into rivers and back to the sea, where it waits to travel again (collection).
What is the name of the step when the Sun turns lake water into invisible vapor?
Most of the water on Earth is salty water in the oceans.
Put the steps in order: the Sun heats the water and it rises as vapor, this is . The vapor cools and makes clouds, this is . Water falls as rain or snow, this is .
A cloud is made of very small drops of liquid water. Which step of the cycle builds a cloud?
