Climate Change Quiz

What is climate change?

• D. A change in the ocean currents

• C. A change in the atmospheric pressure

• B. A change in the weather for a short period of time

• A. A change in the average conditions in a region over a long period of time

Answer explanation

Climate change refers to a change in the average conditions in a region over a long period of time, not just short-term weather variations.

What is the difference between weather and climate?

• A. Weather is the long-term conditions in a region, while climate is the short-term conditions

• D. Weather and climate are the same thing

• B. Weather describes the conditions outside right now, while climate describes the expected weather over a long period of time

• C. Weather is only about temperature, while climate includes rainfall

Answer explanation

Weather describes the conditions outside right now, while climate describes the expected weather over a long period of time. Therefore, the correct choice is B.

What does global climate change refer to?

• A. Changes in the weather for a specific year

• D. Changes in the ocean currents

• C. Changes in the atmospheric composition

• B. Changes in the average long-term conditions over the entire Earth

Answer explanation

Global climate change refers to changes in the average long-term conditions over the entire Earth, making option B the correct choice.

What is the greenhouse effect?

• D. Effect of volcanic eruptions on climate

• C. Effect of the ocean currents on climate

• B. Warming effect of the Earth's atmosphere

• A. Cooling effect of the Earth's atmosphere

Answer explanation

The greenhouse effect refers to the warming effect of the Earth's atmosphere by trapping heat from the sun, leading to an increase in temperature.

What causes Earth's climate to warm?

• A. Natural cooling cycles

• D. Increase in volcanic activity

• B. Human activities changing the greenhouse effect

• C. Decrease in solar radiation

Answer explanation

Human activities changing the greenhouse effect is the primary cause of Earth's climate warming due to increased emissions of greenhouse gases.

Why is it important to understand Earth's climate as a system?

• C. To study the effects of earthquakes

• B. To understand the impact of human activities on climate

• D. To explore outer space

• A. To predict daily weather accurately

Answer explanation

To understand the impact of human activities on climate, it is important to study Earth's climate as a system to assess the changes caused by human actions.

What are the effects of Earth's warming climate?

• D. Decrease in global temperatures

• A. Decrease in hurricanes and heat waves

• C. Increase in intensity of storms and heat waves

• B. Increase in snowfall and ice cover

Answer explanation

The correct choice is C. Increase in intensity of storms and heat waves due to Earth's warming climate.

What do greenhouse gases do in Earth's atmosphere?

• B. Trap heat and warm the Earth

• A. Cool down the Earth

• C. Increase cloud cover

• D. Decrease rainfall

Answer explanation

Greenhouse gases trap heat in Earth's atmosphere, leading to warming of the planet. This process is known as the greenhouse effect.

How do scientists know that Earth's climate is changing?

• A. By observing changes in the moon's orbit

• D. By measuring ocean salinity

• B. By studying ancient fossils

• C. By analyzing temperature data over many years

Answer explanation

Scientists know that Earth's climate is changing by analyzing temperature data over many years, which shows trends and patterns indicating a shift in climate.

What is a possible consequence of the melting ice caps due to Earth's warming climate?

• A. Increase in sea levels

• B. Expansion of polar bear habitats

• C. Decrease in global temperatures

• D. Growth of coral reefs

Answer explanation

Melting ice caps lead to an increase in sea levels due to the release of stored water, impacting coastal areas.
