Introduction
Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the water cycle, is driven by energy from the sun. The water cycle is crucial to the existence of life on our planet.
The Water Cycle
During part of the water cycle, the sun heats up liquid water and changes it to a gas by the process of evaporation. Water that evaporates from Earth's oceans, lakes, rivers and moist soil rises up into the atmosphere.
The process of evaporation from plants is called transpiration. (In other words, it's like plants sweating.)
As water (in the form of gas) rises higher in the atmosphere, it starts to cool and become a liquid again. This process is called condensation. When a large amount of water vapor condenses, it results in the formation of clouds.
When the water in the clouds gets too heavy, the water falls back to the earth. This is called precipitation.
When rain falls on the land, some of the water is absorbed into the ground forming pockets of water called groundwater. Most groundwater eventually returns to the ocean. Other precipitation runs directly into streams or rivers. Water that collects in rivers, streams and oceans is called runoff.
Task
You will need to present another example of a water cycle presentation bases on what we have discuss in the introduction.
Process
Discuss and elaborate your example of water cycle presentation in a detailed manner ways.
