Water Cycle Questionnaire

WATER CYCLE QUESTIONNAIRE

1. What does the water cycle do to the Earth?

1. EVAPORATION

2. TRANSPIRATION

3. CONDENSATION

4. INFILTRATION

5. SURFACE RUNOFF

2. What’s the name of the zone where the sunlight doesn’t reach?

Aphotic Zone.

3. Where does the Humboldt Current come from?

The Humbolt Current starts at the top of the Southern Central Zone of our country (central zone of Chile).Pacific Ocean in front of Chile.

4. Why is the water at the beach liquid and the water on the mountains solid? Name 2 environmental conditions.

Because the water in the mountains is at high altitude, with low temperatures that freeze the water make it solid.

Examples of environmental conditions: snow or frost.

The sea water is at lower altitude with higher temperatures and sea salt prevents the freezing.

5. What do we call the tide when it reaches its maximum level?

High Tide.

6. What do we call the tide when it reaches its minimum level?

Low Tide

7. The photic and aphotic zones are defined according to its…?

About arrive or don´t arrive the sunlight…

Sunlight reaches = Photic Zone

No sunlight reaches =Aphotic Zone

8. Explain condensation:

Water in its gaseous state cools and forms clouds. It returns to Earth in the form of rain, snow or hail.

9. Explain evaporation:

The sun heats the surface of Earth and the water in the rivers, seas and oceans. The water turns to gas and passes to the air.

10. Explain accumulation:

The water from condensation and precipitation accumulates in oceans, rivers and lakes. After that, the accumulated water will evaporate. A portion of the accumulated water is in the ground to allow the existence of trees and plants.

11. Explain the cleaning process of the water cycle:

The water is cleaned in the process of water cycle, because the water in the 3 states: liquid, solid and gaseous is recycled. The contact with de sun, wind and ground allows the natural balance and clean the water.

12. What positive actions can you take to prevent water waste and contamination? 2 examples.

• I can dispose of used oil in a bottle rather than throw it in the sewer. 1 liter of waste oil contaminates 100 liters of water.

• I can put a bottle in the toilet tank to save water.

13. Why do lakes get easily polluted?

Human building near of lakes contaminated its. Because many toxic industrial wastes reach
