Weather Review

The mixture of gases that surrounds Earth and make it suitable for living things is called its____________. 

• condensation
• anemometer
• evaporation
• atmosphere

The diagram shows the layers of Earth's atmosphere. In which layer would water vapor be found? 

• mesosphere
• stratosphere
• troposphere
• thermosphere

Earth's atmosphere is composed of several different gasses. Which statement about these gasses is correct? 

• Earth's atmosphere is mostly made of carbon dioxide. 
• Earth's atmosphere is mostly made of nitrogen.
• Earth's atmosphere is mostly made of oxygen. 
• Earth's atmosphere is made of equal parts of nitrogen, oxygen, and other gases. 

You notice a puddle on the side of the road. The next day the puddle is smaller and by the third day, the water has disappeared. Which phase of the water cycle did you observe? 

• condensation
• evaporation 
• precipitation
• runoff

Liquid water is heated by the sun and becomes water vapor before it rises into the air. What could you observe to show evidence of the next phase of the water cycle? 

• clouds
• rain
• humidity 
• flowers blooming

Runoff is the process of: 

• water cooling and turning into droplets
• water falling from clouds
• water heating and turning into vapor
• water returning to the oceans or lakes

What causes precipitation to fall as either rain or snow? 

• The air temperature
• The amount of clouds in the sky
• The amount of water that evaporated before the storm
• The thickness of the cloud layer

Study the diagram of the water cycle. Which phase of the water cycle is not labeled? 

• run off
• condensation
• evaporation
• precipitation

A student saw this advertisement in a magazine. How is this advertisement inaccurate in describing the water cycle? 

• Precipitation does not come from clouds.
• A cloud is not made up of water droplets. 
• Heat changes liquid into vapor, not vapor into liquid. 
• None of the other answer choices.
