 "process paragraph : : During evaporation the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam. The water vapor or steam leaves the river, lake or ocean and goes into the air. Water vapor in the air gets cold and changes back into liquid, forming clouds, which is called condensation. Precipitation occurs when so much water has condensed that the air cannot hold it anymore. Water falls back to the earth in the form of rain, hail, sleet or snow. When water ends up on land, it will either soak into the earth and become part of the "ground water" for animals or plants to drink. It may also run into the oceans, lakes, or rivers where the cycle starts again. ", "event : The water vapor or steam leaves the river, lake or ocean and goes into the air.", "entity : water"
