From course to practice: the water cycle
Fixed example prepared to discover the journey. It does not come from a Fichea generation and is not created live.
Read the source course: How does water circulate?
A circulation with several paths
The water cycle is the circulation of water between the Earth’s surface, the underground and the atmosphere. Water can stay in an ocean, a lake, a glacier or an underground aquifer. It does not always follow the same path or move at the same speed. This presentation describes five phenomena, without covering every possible exchange.
Evaporation
Evaporation is the change of liquid water into water vapor, an invisible gas. It can happen at the surface of a lake or a puddle, without the water boiling. The Sun’s energy favors evaporation. The water vapor then joins the air.
Condensation
Condensation is the change of water vapor into liquid water. When humid air cools enough, part of its vapor can form tiny droplets. Clouds are made of water droplets or ice crystals, not visible water vapor. The formation of ice crystals involves other changes of state than the liquid condensation described here.
Precipitation
Precipitation is water falling from the clouds to the ground, as rain, snow or hail. In a cloud, the droplets or ice particles can grow. They fall when air movements are no longer enough to keep them suspended. Not every droplet in a cloud therefore turns into rain right away.
Infiltration
Infiltration is water entering the soil from its surface. Some of the water is stored there temporarily; some can move deeper and help feed groundwater. The amount that infiltrates depends in particular on how permeable the soil is and how much water it already holds. So not all rainwater goes straight into an aquifer.
Runoff
Runoff is water flowing over the soil surface. Under the effect of gravity, this water can reach a stream, a river, a lake or the sea. Infiltration and runoff can happen during the same rainfall: they are not two mandatory steps that all water follows in the same order.
Read the example sheet: the key concepts
- Overview
- Water moves between the surface, the subsurface and the atmosphere, along several paths.
- Course excerpt: “The water cycle is the movement of water between the Earth’s surface, the subsurface and the atmosphere.”
- Evaporation
- Liquid water → water vapor. This change can happen without boiling.
- Course excerpt: “Evaporation is liquid water turning into water vapor, an invisible gas. It can happen at the surface of a lake or a puddle, without the water boiling.”
- Condensation
- Water vapor → liquid water.
- Course excerpt: “Condensation is water vapor turning into liquid water.”
- Precipitation
- Water falls from clouds as rain, snow or hail.
- Course excerpt: “Precipitation is water falling from clouds to the ground as rain, snow or hail.”
- Infiltration
- Water enters the soil. Some of it can then feed groundwater.
- Course excerpt: “Infiltration is water entering the soil from its surface. Some of the water is stored there temporarily; some can move deeper and help feed groundwater.”
- Runoff
- Water flows over the soil surface; it does not necessarily enter the soil.
- Course excerpt: “Runoff is water flowing over the soil surface.”

1. Which change does evaporation describe?
Answer: Liquid water becomes water vapor.
Evaporation turns liquid water into water vapor. It refers neither to water entering the soil nor to water flowing over the surface.
Course excerpt: “Evaporation is liquid water turning into water vapor, an invisible gas.”
2. Which change matches the condensation described in this course?
Answer: Water vapor becomes liquid water.
The condensation described here turns vapor into liquid. It is the opposite change to evaporation.
Course excerpt: “Condensation is water vapor turning into liquid water.”
3. Which situation is precipitation?
Answer: Snow falls from a cloud to the ground.
Snow is a form of precipitation, like rain and hail. The term is not limited to liquid water.
Course excerpt: “Precipitation is water falling from clouds to the ground as rain, snow or hail.”
4. Which movement is infiltration?
Answer: Water seeps into the soil from its surface.
Infiltration is water entering the soil. Running along a path describes surface flow instead.
Course excerpt: “Infiltration is water entering the soil from its surface.”
5. After rain, water runs over the ground toward a stream. What is this phenomenon called?
Answer: Runoff.
The water moves over the surface: that is runoff. Infiltration is water entering the soil.
Course excerpt: “Runoff is water flowing over the soil surface.”
This example simplifies the water cycle. Compare the answers with the source course; no teacher validation is attested.

Frequently asked questions
Can you create a multiple-choice quiz from a course PDF?
Yes. Import your PDF, select the courses to work on and set up a quiz in Fichea. You can also start from a sheet. Check the corrections against your sources; access and quotas depend on your plan.
Is the quiz generator free?
Fichea offers a free account with no credit card. Quiz features and quotas depend on the plan listed on the Pricing page. The public demo uses a prepared example and doesn't require an account.
Why generate a quiz from my course notes?
Because the quiz then covers the content you're actually supposed to learn, which narrows the gap with your chapter or your exam.
Is a quiz enough to learn?
It complements understanding and practice. Depending on the subject, you also need to redo exercises, write, or solve problems.
Can I use the quiz after a sheet?
Yes. The Fichea flow is designed to take you from course notes to a sheet, then to active recall.
