9.
The way water moves from the clouds to the earth and back to the clouds again is called ____.
Correct Answer
B. The water cycle
Explanation
The water cycle refers to the continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, and runoff. Water evaporates from bodies of water, forms clouds, and then returns to the Earth as precipitation. This process is essential for the distribution of water resources and the maintenance of ecosystems.
10.
When water changes from a liquid into a gas, it _____.
Correct Answer
D. Evaporates
Explanation
When water changes from a liquid into a gas, it evaporates. Evaporation is the process by which water molecules gain enough energy to break free from the liquid phase and become a gas. This occurs when the temperature of the water increases, causing the water molecules to move faster and eventually escape as water vapor. Evaporation is an important part of the water cycle and contributes to the formation of clouds and precipitation.
11.
When water changes from a gas to a liquid, it _____.
Correct Answer
B. Condenses
Explanation
When water changes from a gas to a liquid, it condenses. This is because condensation occurs when water vapor cools down and loses energy, causing the water molecules to come closer together and form a liquid. This process is commonly observed when warm, moist air comes into contact with a cool surface, such as when water droplets form on the outside of a cold glass.
12.
What measure temperature?
Correct Answer
A. Thermometer
Explanation
A thermometer is a device used to measure temperature. It consists of a long, narrow glass tube filled with a liquid, usually mercury or alcohol, that expands or contracts with changes in temperature. The liquid rises or falls in the tube, providing a numerical value that indicates the temperature. This makes the thermometer an appropriate tool for measuring temperature accurately. Anemometer measures wind speed, tornadoes are violent windstorms, and spring is a season, none of which directly measure temperature.
13.
What measures how fast the wind is blowing?
Correct Answer
C. Anemometer
Explanation
An anemometer is a device that measures the speed or velocity of wind. It typically consists of cups that rotate when the wind blows, and the rotation is then converted into a measurement of wind speed. Therefore, an anemometer is the correct instrument for measuring how fast the wind is blowing.
14.
What happens to water when it evaporates?
Correct Answer
C. It goes from a liquid to a gas
Explanation
When water evaporates, it undergoes a phase change from a liquid to a gas. This process occurs when the water molecules gain enough energy to overcome the forces of attraction between them and escape into the air as water vapor. Evaporation is a natural process that happens at the surface of water bodies, such as oceans, lakes, and even puddles. It is an essential part of the water cycle and plays a crucial role in the Earth's climate system.
15.
What happens to water when it condenses?
Correct Answer
A. It goes from a gas to a liquid
Explanation
When water condenses, it changes from a gas state to a liquid state. This process occurs when water vapor cools down and loses energy, causing the water molecules to come closer together and form liquid droplets. Condensation commonly happens when warm, moist air comes into contact with a cold surface or when the air temperature decreases.
