It begins: The water on Earth is used again and again in a never-ending journey called the water cycle. --- [Mova](https://md.mova.elamur.ai/free/en/) · [this page in HTML](https://mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/) [home](https://md.mova.elamur.ai/free/en/) / [corpora](https://md.mova.elamur.ai/free/en/corpora/) / [school](https://md.mova.elamur.ai/free/en/corpora/school/) / [World](https://md.mova.elamur.ai/free/en/corpora/school/world/) / The water cycle # The water cycle Lesson 14 of the world course of Mova's primary school: 17 sentences, each with its syntax tree and pragmatics.

How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/world/14-the-water-cycle/). - [0](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/0/) — The water on Earth is used again and again in a never-ending journey called the water cycle. - [1](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/1/) — The Sun warms seas, lakes, rivers and soil, and water evaporates into the air as invisible vapour; plants also give off water vapour from their leaves. - [2](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/2/) — As the moist air rises it cools, and the vapour condenses on tiny specks of dust, smoke and sea salt into droplets that make clouds. - [3](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/3/) — When the droplets join together and grow heavy, they fall as rain, snow or hail: this is called precipitation. - [4](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/4/) — The water runs over the land in streams and rivers or soaks into the ground, flows back to the sea; this gathering of water back into rivers, lakes and seas is called collection, and the journey starts again. - [5](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/5/) — For example, a raindrop that lands on you today may once have been in an ocean, in a cloud over another continent, or even drunk by a dinosaur. - [6](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/6/) — The heat of the Sun drives the water cycle. - [7](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/7/) — Evaporation lifts water from seas, lakes and soil into the air. - [8](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/8/) — Plants give off water vapour from their leaves; this is called transpiration. - [9](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/9/) — Air cools as it rises, so water vapour condenses high up into clouds. - [10](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/10/) — A cloud is made of millions of tiny water drops, or of tiny ice crystals where it is very cold. - [11](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/11/) — Rain, snow, sleet and hail are all called precipitation. - [12](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/12/) — Some rainwater soaks into the ground and becomes groundwater, which feeds wells and springs. - [13](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/13/) — When seawater evaporates the salt stays behind, so rain is fresh water. - [14](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/14/) — Most of Earth's water is salty water in the oceans; only a small part is fresh. - [15](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/15/) — Much of Earth's fresh water is frozen in ice sheets, huge sheets of ice covering land, and glaciers, slow rivers of ice. - [16](https://md.mova.elamur.ai/free/en/corpora/school/world/14-the-water-cycle/16/) — The amount of water on Earth stays about the same; it just keeps moving around. - ← previous: [Evaporation and condensation](https://md.mova.elamur.ai/free/en/corpora/school/world/13-evaporation-condensation/) - next →: [Weather: pressure, wind, clouds and storms](https://md.mova.elamur.ai/free/en/corpora/school/world/15-weather/) - ↑ back to [World](https://md.mova.elamur.ai/free/en/corpora/school/world/)
