QCM : Global Warming Effects (6 questions)

Questions et réponses du QCM

1. Which change in the Earth's climate is identified as an effect of global warming?

The Earth's sea level is decreasing.
The Earth's temperature is decreasing.
The Earth's temperature is increasing.
The Earth's temperature is stable.

The Earth's temperature is increasing.

Explication

Global warming is associated with an increase in the Earth's temperature. A decrease reverses the stated trend, a stable temperature removes the change, and falling sea level confuses two different effects.

2. What is happening to the ice at the North Pole as the climate warms?

It is melting.
It is rising.
It is moving.
It is freezing.

It is melting.

Explication

The stated effect is that ice in the North Pole is melting. Freezing reverses this process, movement is not the identified change, and rising refers to sea levels.

3. Which trend in sea levels is associated with global warming?

They are decreasing.
They are increasing.
They are staying constant.
They are melting.

They are increasing.

Explication

Sea levels are increasing as an effect of global warming. Decreasing reverses the trend, staying constant denies a change, and melting describes ice rather than sea levels.

4. A report links danger to a community with harmful human activities. Which relationship does this illustrate?

Sea-level rise puts populations in danger.
Extreme weather puts human activities in danger.
Populations put human activities in danger.
Human activities put populations in danger.

Human activities put populations in danger.

Explication

The stated relationship is that populations are in danger because of human activities. Natural causes and extreme weather are different explanations, while reversing the relationship makes populations the cause.

5. A region experiences unusually severe weather as global warming progresses. What link does this illustrate?

Global warming causes extreme weather.
Global warming causes drought alone.
Population danger causes extreme weather.
Extreme weather causes global warming.

Global warming causes extreme weather.

Explication

Global warming is identified as a cause of extreme weather. Reversing the causal direction, narrowing the effect to drought, or substituting population danger changes the stated relationship.

6. A coastal town finds that rising sea levels are making its freshwater unsafe to drink. Which consequence best explains the change?

The freshwater is becoming scarce from drought.
The freshwater is becoming drinkable.
The freshwater is becoming undrinkable.
The town's homes are being flooded.

The freshwater is becoming undrinkable.

Explication

Rising sea levels are linked to freshwater becoming undrinkable. Making water drinkable reverses the consequence; drought-related scarcity and flooded homes are distinct risks.
