# Gizmo Water Cycle Answers

Posted on

Water Cycle is one of the science materials on Gizmo that allows you to discover the different paths water takes when it moves from Earth’s surface to the atmosphere and back. Water Cycle here means the motion form repeating circuit where Water on Earth is always in motion.

On Gizmo, you will be required to take the Water Cycle test, after learning about it. If you are accidentally looking for Gizmo Water Cycle answers, you do not have to worry since this post will show you the answers of the Gizmo Water Cycle. Okay, let’s check the answers out!

Gizmo Water Cycle Answers

In this post, we will show you the Water Cycle answers on Gizmo from signnow.com. The test about Water Cycle consists of two sections: Warming up and Activity. The correct answers are highlighted in bold font.

It’s important to note, before using the Gizmo, you will have to answer the question. Well, the aim of this question is to activate prior knowledge and get students thinking. Students are not expected to know the answers to the Prior Knowledge Question.

• Example question: The water that comes out of your faucet at home used to be in the ocean. How did water get from the ocean to your water faucet?
• Sample answer: Water in the oceans was evaporated by the Sun, and then the water condensed to form clouds. The clouds moved over land, where they rained. Some of this rain fell into streams and rivers which led to a reservoir. The water was then pumped to my house.

Warming Up

There are some warming up questions you should answer before you take the activity. Here are they:

1. Click Oceans. What percentage of Earth’s water is found in the oceans? 97.25%
2. Click Atmosphere. How does the Sun cause water to move from the oceans to the atmosphere? Ocean water is heated by the Sun, causing it to evaporate into the atmosphere.
3. Click Clouds. How do clouds form? Water vapor in the atmosphere cools and condenses.
4. Click Precip (rain). (Precip is short for precipitation or water falling to Earth’s surface) What causes it to rain? Rain occurs when water droplets in clouds are large enough to fall.
5. Click Oceans again and then choose the Path tab. Because it has the same beginning and end, the path is a complete cycle. How many steps does this cycle have? 5 steps

Activity – The Water Cycle

If you take this water cycle test, you can choose the ‘Simulator’ tab and then click on the ‘Reset’.

Question: What are the parts of the water cycle?

1. Collect data: Create two water cycles using the Gizmo. Each cycle should have at least four steps and should begin and end at the same location. Choose any starting point from the list on the right. When the cycle is complete, choose the PATH tab and write the steps below.
To answer this question, each student’s answer will vary. So, you need to check that each cycle has the same beginning and ending point.
Cycle 1:
Cycle 2:
2. Analyze: Use the information presented in the Gizmo to answer the following questions.
A. What percentage of Earth’s water can be found in soil? 0.005%
B. What percentage of Earth’s water is stored in ice and snow? 1.9%
C. What percentage of Earth’s freshwater is stored in ice and snow? 68.7%
D. What percentage of Earth’s water is found in lakes? 0.009%
E. What is transpiration? You can click the ‘Vegetation’ button. Plants releasing water vapor from their leaves.
F. What human activity uses the most water worldwide? Agriculture (70%)
G. What human activity uses the most water in the United States? Industry (59)
H. What organisms break down chemical wastes in a treatment plant? Bacteria
I. What is an aquifer? An aquifer stores water in the ground.
J. What is a reservoir? A body of water (often a lake) that stores water for human use.
K. In what ways can runoff be a problem? Runoff causes flooding and erosion and can also wash pollutants into rivers.
3. Define: A phase change is a change from one state to another, such as from a liquid to a gas. Based on what you have read in the Gizmo, fill the blanks with the words ‘liquid’, ‘gas’ or ‘solid’ to define each change.
Evaporation → Change from a liquid to a gas
Condensation→  Change from a gas to a liquid
Melting → Change from a solid to a liquid
Freezing → Change from a liquid to a solid
4. Practice: Fill in the process that causes each transition. Your choices are evaporation, condensation, precipitation, melting and freezing.
A. Ocean → Atmosphere: Evaporation
B. Atmosphere ↓ Clouds: Condensation
C. Cloud → Snow: Freezing
D. Glacier (river of ice) → River: Melting
E. Cloud → Soil: Precipitation
5. Practice: Fill in the two processes that cause each of the following transitions.
A. Ocean → Cloud: Evaporation, Condensation
B. Cloud → Glacier: Freezing, precipitation (or precipitation, freezing)
6. Think and Discuss: Water covers over two-thirds of Earth’s surface. Yet water shortages are a major problem for many people around the world. Why do you think this is the case?
To answer this question, you can answer varied questions, since there are many acceptable answers to this question.
Here’s the sample answer:
Over 97% of Earth’s water is salt water, which is not useful for people. Most of the freshwater on Earth is locked up in glaciers and ice caps, so it cannot be used either. Only about 1% of Earth’s water is available for human use. Many parts of Earth are very dry, and there is not enough water for agriculture, industry and human consumption. Some people use excessive amounts of water, leaving less for others to use.

Okay, those are the questions and answers as your reference when taking the Gizmo Water Cycle test. Of course, you can answer those questions varied, since there will be acceptable answers to those questions.
