Climate Change Assessment

Climate change refers to significant changes in global …………………………and ………………………….. patterns

• temperature / weather

• precipitation / climate

Answer explanation

Climate change involves significant alterations in global temperature and weather patterns. The correct choice highlights how temperature affects weather, making 'temperature / weather' the appropriate answer.

Although climate change is a ………………………….…, human activities have a great impact in these changes.

• artificial phenomenon

• reaction to

• natural phenomenon

Answer explanation

The correct choice is 'natural phenomenon' because climate change primarily results from natural processes, although human activities significantly influence its pace and effects.

Many species are struggling to adapt due to shifting environmental conditions . They are also having difficulties in finding ………………..………………….. and …………………………..……………..… to thrive.

• food / climate

• food / habitat

• habitat / water

Answer explanation

The correct choice is 'food / habitat' because species need both adequate food sources and suitable habitats to thrive. While climate and water are important, the context emphasizes the need for food and habitat specifically.

Extreme weather events, such as ……………………………and ……………………………., are becoming more and more frequent and intense.

• hurricanes / droughts

• droughts / deforestation

Answer explanation

Extreme weather events like hurricanes and droughts are increasingly frequent and intense due to climate change. Deforestation, while impactful, does not fit as a weather event, making hurricanes and droughts the correct choice.

Renewable energy sources like ……………………… and ……………………..may help to reduce greenhouse gas emissions.

• solar power

• wind energy

• both are correct

Answer explanation

Both solar power and wind energy are renewable sources that can significantly reduce greenhouse gas emissions, making 'both are correct' the right choice.

What is one major consequence of climate change on biodiversity, as discussed in the text?

• Decline in certain animal populations

• Improvement in global dietary habits

• Enhanced growth of urban areas

Answer explanation

One major consequence of climate change on biodiversity is the decline in certain animal populations, as changing climates disrupt habitats and food sources, leading to reduced survival rates.

According to the text, which action can help reduce greenhouse gas emissions?

• Increasing waste production

• Utilizing more coal and oil

• Emphasizing wind and solar power.

Answer explanation

Emphasizing wind and solar power is a key action to reduce greenhouse gas emissions, as these renewable energy sources produce little to no emissions compared to fossil fuels like coal and oil.

How do human activities contribute to climate change as mentioned in the text?

• By releasing greenhouse gases from fossil fuels

• Through the natural cycle of the earth

• Through the re-forestation of urban areas

Answer explanation

Human activities, particularly the burning of fossil fuels, release greenhouse gases like CO2 into the atmosphere. This accumulation of gases traps heat, leading to climate change, making this the correct choice.

What impact does the melting of polar ice caps have on Earth's geography?

• Forms new mountain ranges

• Reduces sea levels worldwide

• A threat to coastal communities due to rising sea levels.

Answer explanation

The melting of polar ice caps leads to rising sea levels, posing a significant threat to coastal communities through increased flooding and erosion, making this the correct choice.

What is a significant effect of deforestation on climate change?

• Increased biodiversity

• Loss of biodiversity

• Improved air quality
