Understanding Global Warming and Climate Change

What is the primary difference between global warming and climate change?

• Global warming is a short-term phenomenon, while climate change is a long-term trend.

• Global warming affects only the polar regions, while climate change affects the entire planet.

• Global warming is caused by natural factors, while climate change is entirely human-induced.

• Global warming refers to the Earth's temperature increase, while climate change includes broader changes in weather patterns.

How does the Earth's atmosphere help maintain a stable temperature?

• By reflecting all sunlight back into space.

• By absorbing and re-emitting heat energy, keeping it close to the Earth's surface.

• By allowing all heat to escape into space.

• By blocking all forms of radiation from reaching the Earth.

Why is the greenhouse effect essential for life on Earth?

• It blocks harmful cosmic rays from reaching the Earth.

• It keeps the Earth's temperature stable and suitable for life.

• It prevents all sunlight from reaching the Earth's surface.

• It allows all heat to escape into space.

Which gases are primarily responsible for the greenhouse effect?

• Oxygen and nitrogen

• Argon and krypton

• Carbon dioxide and methane

• Helium and neon

What has been the trend in Earth's temperature over the past 100 years?

• It has fluctuated without any clear trend.

• It has increased by almost a whole degree.

• It has remained constant.

• It has decreased by several degrees.

What is one major consequence of global warming on weather patterns?

• A decrease in the frequency of hurricanes

• An increase in rare weather events like droughts and floods

• A stabilization of global temperatures

• A reduction in sea levels

What are two reasons for rising sea levels due to global warming?

• Melting ice and thermal expansion of seawater

• Increased rainfall and river flow

• Increased volcanic activity and tectonic shifts

• Decreased evaporation and increased cloud cover

How might climate change affect species that are well-adapted to their current environments?

• They will remain unaffected by climate change.

• They will thrive and expand their habitats.

• They may struggle to survive or need to migrate.

• They will become more resistant to diseases.

What is a potential impact of climate change on biodiversity?

• An increase in genetic diversity within species

• An increase in the number of species worldwide

• A stabilization of ecosystems

• A decrease in biodiversity due to species extinction

What is one way species are responding to changing temperatures due to climate change?

• By hibernating for longer periods

• By becoming nocturnal

• By migrating towards the poles

• By moving towards the equator
