Climate Change Impacts Questions

Multiple choice

Which of the following is NOT a way that oceans influence Earth's ecosystems?

  1. they transfer heat around the world

  2. they provide renewable energy resources

  3. they provide a barrier to erosion

  4. they play a key role in the carbon cycle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

While oceans provide many services, they do not act as a physical barrier to erosion; in fact, wave action is a primary cause of coastal erosion.

Multiple choice

What is climate change?

  1. The change of global temperature

  2. The general climate change patterns of a particular area

  3. It is global warming
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Climate change refers to long-term shifts in temperatures and weather patterns, often used to describe the changing climate of specific regions or the planet as a whole.

Multiple choice

What is the problem with global warming?

  1. Sea levels are rising and covering land

  2. Permafrost is melting and buildings will sink

  3. The temperatures will be too hot to survive in

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Global warming causes a variety of environmental issues, including rising sea levels, melting permafrost, and extreme temperature increases. Therefore, all listed options are correct.

Multiple choice

Effects of global warming include:

  1. rising sea levels

  2. melting of permafrost

  3. melting glaciers

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Global warming leads to the melting of glaciers and permafrost, which in turn contributes to rising sea levels. All these phenomena are interconnected effects of a warming climate.

Multiple choice

What is global warming?

  1. ice caps melting

  2. sea levels rising

  3. the gradual warming of the globe

  4. more deserts
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Global warming refers specifically to the long-term, gradual increase in the Earth's average surface temperature. The other options are symptoms or consequences of this process.

Multiple choice

Will climate change impacts be the same in all locations on Earth?

  1. The results are the same across the globe

  2. There is no scientific evidence to support an answer

  3. The impacts will vary

  4. All answer choices are accurate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Climate change affects different regions in diverse ways due to local geography and atmospheric patterns. For example, some areas will experience severe droughts and heatwaves, while others may face increased flooding and heavier rainfall.

Multiple choice

These observations inform us that Earth's average temperature is increasing, except:

  1. The 20 warmest years on record have all occurred since 1995

  2. Rising temperatures are melting ice on land, lakes, & sea

  3. Animals are increasing in diversity in the wild.

  4. Winter storms increased in frequency & intensity since 1950
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

While rising temperatures, melting ice, and changing storm patterns are direct physical indicators of global warming, an increase in wild animal diversity is not a standard observation used to measure global temperature rise. In fact, climate change often threatens biodiversity.

Multiple choice

A primary reason we know that human activity is causing global warming is:

  1. CO2 has decreased in the atmosphere over the past ten years

  2. Earth's atmosphere is getting thinner

  3. We can correlate the rise of CO2 with human activities

  4. All answer choices are accurate
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Scientists can trace the rise of atmospheric carbon dioxide directly to human activities, such as burning fossil fuels, through isotopic analysis and historical emissions data. This correlation, along with physical models, confirms that human actions are driving modern global warming.

Multiple choice

What happens when CO2 & other greenhouse gases increase in our atmosphere?

  1. Average global temperatures decrease

  2. Average global temperatures increase

  3. The Earth's magnetic field changes direction
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Greenhouse gases trap heat radiating from the Earth's surface that would otherwise escape into space. When the concentration of these gases increases, more heat is retained, leading to an increase in average global temperatures.

Multiple choice

Hotter summer temperatures are caused by:

  1. being closer to the Sun.

  2. more direct sunlight and longer days.

  3. less direct sunlight and shorter days.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Summer heat is caused by the tilt of the Earth towards the Sun, which results in more direct solar radiation and longer daylight hours. The distance from the Sun actually varies very little and is not the cause of seasonal temperature changes.

Multiple choice

How has climate change impacted the environment?

  1. It has increased the amount of trash in the ocean.

  2. It has lowered the average sea level by 1.2 meters (4 feet).

  3. It has increased the size of the Arctic.

  4. It has decreased the size and number of glaciers.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Rising global temperatures caused by climate change lead to the melting of glaciers and ice sheets worldwide. This melting directly reduces the size and number of glaciers and contributes to rising sea levels.

Multiple choice

Why is the Antarctic Circumpolar Current important to the world’s climate?

  1. It redistributes temperature & salt throughout the ocean

  2. All answer choices are accurate

  3. It drives CO2 gas exchange with the atmosphere

  4. Density differences make it the "mixer of the deep oceans"
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Antarctic Circumpolar Current is a critical driver of global climate, influencing heat distribution, carbon exchange, and deep ocean mixing.
