Question

1. Which sentence best shows a cause-and-effect relationship about climate change?

A. The ocean is large and full of life.

B. Factories release greenhouse gases, so global temperatures rise.

C. Many birds migrate every year.

D. Trees provide shade and homes for animals.



2. Which effect is most directly caused by rising global temperatures?

A. Increased snowfall in all regions.

B. Melting of polar ice and glaciers.

C. More volcanic eruptions worldwide

D. Decrease in Earth's gravity



3. Which pair correctly matches a human cause of climate change with its effect?

A. Planting trees → higher sea levels.

B. Burning fossil fuels → stronger greenhouse effect

C. Recycling paper → more carbon dioxide in the air

D. Switching to renewable energy → more plastic pollution



4. Read this short explanation: "When greenhouse gases trap more heat, ocean water warms. Warmer water expands and ice melts." Which sequence shows the correct cause → effect order from that explanation?

A. Ice melts → greenhouse gases increase → ocean warms

B. Greenhouse gases trap heat → ocean warms → sea level rises

C. Ocean cools → ice forms → temperatures drop

D. Sea level rises → greenhouse gases decrease → oceans warm



5. Which statement is an effect of increased carbon dioxide in the atmosphere?

A. Plants stop using sunlight

B. Global average temperatures tend to increase

C. The moon moves farther from Earth

D. Rivers flow uphill



6. Which of the following is a valid cause that can lead to more extreme weather events?

A. Decrease in sunlight reaching Earth

B. Increase in atmospheric energy from higher temperatures

C. Earth rotating faster on its axis

D. Plants producing less oxygen at night



7. Which explanation most clearly uses cause-and-effect to argue for action to reduce climate change?

A. "We should act because many people like sunny weather."

B. "If we reduce emissions now, we can slow warming and protect coastal communities from flooding."

C. "Rising temperatures are funny and unpredictable."

D. "More cars on the road always mean better roads."



8. An author organizes a passage by first describing human activities that add greenhouse gases, then showing how those gases change climate patterns, and finally describing impacts on ecosystems. Which text structure is the author using?

A. Compare and contrast

B. Problem and solution

C. Cause and effect

D. Sequence of instructions



9. Which sentence would be the best topic sentence for a paragraph that explains causes and effects of climate change?

A. "Climate change causes a variety of environmental effects, such as stronger storms and changing habitats."

B. "Many people enjoy visiting beaches in the summer."

C. "The solar system has eight planets that orbit the Sun."

D. "Reading books helps students learn new information."



10. Which sentence best shows a cause-and-effect relationship about climate change?

A. "Forest habitats are important places where many animals live."

B. "Rising temperatures can melt polar ice, so sea levels may rise."

C. "Many scientists study weather and collect data each year."

D. "Trees provide shade and make parks cooler."

Answer 1

1. B — Factories release greenhouse gases, so global temperatures rise. (cause → effect)

2. B — Melting of polar ice and glaciers. (direct result of warming)

3. B — Burning fossil fuels → stronger greenhouse effect. (human cause → effect)

4. B — Greenhouse gases trap heat → ocean warms → sea level rises. (correct cause→effect order)

5. B — Global average temperatures tend to increase. (effect of more CO2)

6. B — Increase in atmospheric energy from higher temperatures. (leads to more extreme weather)

7. B — "If we reduce emissions now, we can slow warming and protect coastal communities from flooding." (clear cause → effect argument)

8. C — Cause and effect. (describes causes, effects, then impacts)

9. A — "Climate change causes a variety of environmental effects, such as stronger storms and changing habitats." (good topic sentence)

10. B — "Rising temperatures can melt polar ice, so sea levels may rise." (cause → effect)
