What is climate change?

 

a sudden change in conditions including temperature and precipitation

 

a change in global temperatures and weather patterns over many years

 

an extreme weather event such as a hurricane or drought

ANSWER: a change in global temperatures and weather patterns over many years

Climate change is happening right now. Over the past 100 years, global temperatures are slowly rising. Weather patterns are changing too. Changes to Earth's oceans, atmosphere, land, and ice all affect the global climate.

An unexpected thunderstorm is an example of:

 

weather

ANSWER: weather

Weather describes the conditions outside in a certain place and time, like what's happening today, this week, or this season. Climate is the typical weather in an area over a long period of time (many years).

What does the atmosphere contain that keeps Earth's surface warm?

 

water vapor and carbon dioxide

 

methane and nitrous oxide

 

carbon dioxide, methane, nitrous oxide, and water vapor

Nope. Try again!
You got it!

ANSWER: carbon dioxide, methane, nitrous oxide, and water vapor

These are all greenhouse gases. They allow sunshine to pass through the atmosphere. But they absorb and hold the heat that radiates back from Earth's surface. This process, called the greenhouse effect, keeps Earth warm.

What is one way that scientists measure global climate?

 

they collect weather data from places with tropical climates

 

they collect weather data from places with extreme climates

 

they collect and average data from weather stations around the world

Nope. Try again!
You got it!

ANSWER: they collect and average data from weather stations around the world

To understand global climate, scientists also measure the temperature and chemistry of the ocean. They gather this data from ships, satellites above Earth, and buoys spread across the oceans.

Where do scientists find evidence that Earth's climate has changed in the past?

 

tree rings

 

glacial ice

 

glacial ice and tree rings

Nope. Try again!
You got it!

ANSWER: glacial ice and tree rings

Tree rings and samples of ancient ice are clues from Earth. They hold important information about what the atmosphere was like in the past, such as temperatures and carbon dioxide concentrations. From this evidence, scientists know that today's warming is different. Temperatures are rising higher and faster than anytime in human history.

Which human actions are causing Earth's climate to warm?

 

building "green" houses that use less energy

 

burning fossil fuels that release greenhouse gases

 

using solar power that relies on energy from the Sun

Nope. Try again!
You got it!

ANSWER: burning fossil fuels that release greenhouse gases

Cars, computers, and other modern machines use  energy. The energy comes from burning  fossil fuels. This releases greenhouse gases into the atmosphere that cause Earth to warm.

NEXT QUESTION
Coastal flooding and drought
7

How does climate change affect people?

 

rising sea levels can flood coastal homes and communities

 

hotter, longer droughts can threaten crops

 

both of these and more

Nope. Try again!
You got it!

ANSWER: both of these and more

And people aren't the only ones affected by changing weather patterns and rising temperatures. Plant and animal habitats, from the Arctic to the tropical oceans, are threatened.

What is the advantage of "clean" energy sources like wind and solar?

 

they produce few or no greenhouse gases

 

they are always less expensive than fossil fuels

 

they rely on non-renewable resources

Nope. Try again!
You got it!

ANSWER: they produce few or no greenhouse gases

"Clean" energy sources like solar, wind, water, and geothermal are renewable. Their supply won't run out. Nuclear energy, natural gas, and carbon capture and storage are other solutions for cutting down greenhouse emissions.

What is the best way to reduce the effects of climate change?

 

conserve energy by using less electricity and fuel

 

switch to "clean" energy sources

 

combine many efforts like these on a worldwide scale

Nope. Try again!
You got it!

ANSWER: combine many efforts like these on a worldwide scale

There is no single solution to address climate change. Instead, it will take a combination of efforts to reduce our carbon dioxide emissions, from individual actions to a government commitment to "clean" energy sources like solar and wind.

10

Which of the following actions can you do to help lessen climate change?

 

walk instead of drive

 

buy less stuff

 

both of these and more

Nope. Try again!
You got it!

ANSWER: both of these and more

Anytime you use less energy, like walking instead of riding in a car, you're putting fewer carbon dioxide emissions into the atmosphere. You can also consume less. In other words, reduce, reuse, and recycle whenever you can.
