Earth's Changing Climate: Chapter 1 Quiz

What role do trees play in climate regulation?

• They release carbon dioxide into the atmosphere.

• They absorb carbon dioxide, a greenhouse gas, helping to mitigate climate change.

• They provide shade and reduce temperature.

• They have no significant impact on climate.

What is global warming?

• The long-term increase in Earth's average surface temperature due to human activities, primarily the burning of fossil fuels.

• A temporary increase in temperature due to seasonal changes.

• The cooling of the Earth's surface due to volcanic activity.

• A natural phenomenon that occurs every few decades.

What is climate variability?

• Natural fluctuations in climate patterns over short periods, such as seasons or years.

• Consistent and predictable changes in climate over long periods.

• The impact of human activities on climate change.

• A sudden and extreme weather event that disrupts normal climate patterns.

What is an ecosystem?

• A community of living organisms and their physical environment interacting as a system.

• A collection of random species living in isolation.

• A group of organisms that do not interact with their environment.

• A network of artificial habitats created by humans.

What does the term 'trend' refer to in data analysis?

• A sudden spike in data points

• A random fluctuation in data

• Overall tendency (for example, a consistent increase) in a set of data over time.

• An isolated data point that does not fit the pattern

What is a carbon footprint?

• The total amount of carbon emissions produced by a vehicle.

• The total amount of greenhouse gases emitted directly or indirectly by an individual, organization, event, or product.

• The measure of how much carbon is stored in trees and plants.

• The total amount of carbon dioxide absorbed by the ocean.

What is climate change?

• Changes in climate over a long period of time that can be caused by natural events or human activities.

• Short-term variations in weather patterns.

• The increase in global temperatures due to urbanization.

• Seasonal changes in temperature and precipitation.

What is the atmosphere?

• The layer of gases surrounding the Earth, crucial for weather and climate.

• A type of weather phenomenon that occurs in the sky.

• The solid outer layer of the Earth that supports life.

• A region of space beyond the Earth's atmosphere.

What are fossil fuels?

• Natural substances like coal, oil, and natural gas that release energy when burned, contributing to climate change.

• Renewable energy sources such as wind and solar power.

• Synthetic materials created from petroleum that do not release energy.

• Minerals found in the earth's crust that are used for construction.

What trend are we seeing in Earth's surface ice?

• Increase

• No change

• Decrease

• Fluctuation
